Converting a list of lists to a single list
I think that itertools may be able to do what I want but I have not been able to figure out how. I want to convert an arbitrary number of lists with an arbitrary number of elements in each list into a single list as follows. Say I have three lists: [[A0,A1,A2], [B0,B1,B2] [C0,C1,C2]] I would like to convert those to a single list that looks like this: [A0,B0,C0,C1,C2,B1,C0,C1,C2,B2,C0,C1,C2,A1,B0,C0,C1,C2,B1,C0,C1,C2,B2,C0,C1,C2,A2,B0,C0,C1,C2,B1,C0,C1,C2,B2,C0,C1,C2] An easier way to visualize the pattern I want is as a tree. A0 B0 C0 C1 C2 B1 C0 C1 C2 B2 C0 C1 C2 A1 B0 C0 C1 C2 B1 C0 C1 C2 B2 C0 C1 C2 A2 B0 C0 C1 C2 B1 C0 C1 C2 B2 C0 C1 C2 -- http://mail.python.org/mailman/listinfo/python-list

Tcl wasn't installed properly
I'm a frequent user of matplotlib on my Windows XP machine. I
recently attempted to install a program that modified my Tcl
installation, and I now get an error message when I attempt to plot
anything in matplotlib. Here is the error message:
---
Traceback (most recent call last):

This probably means that Tcl wasn't installed properly.

I attempted a complete reinstall of python (hoping it would reinstall
Tcl with correct file paths), but I get the same error. Any
suggestions would be appreciated.

That is where my installation is located too. Why is it insisting on
looking in "C:\Python25\lib\tcl8.4"? Can I change where it is looking?

I figured out the solution. The program I installed must have changed
my windows path names. I changed TCL_LIBRARY and TK_LIBRARY to the
location of my tcl installation, and it works fine now.

Trying to read from a text file to generate a graph
I am going though a struggle with this and just don't see where it fails. I am using the Dual Bar Graph.py program from https://matplotlib.org/stable/gallery/index.html website. The file from the web site works so that shows that all my installations are complete. My program, LibreGraphics 05.py program runs but the graph is all smutched up. I am pulling data from the EXCEL-FILE.txt into the program, selecting three values for each line and creating three variables formatted as is shown in the original demo file. When you run the program, choose 112 when prompted. You will see the values of the variables I want to pass to the graph section of the code. If the values are hardcoded, the graphs look good. When the variables generated by my section of the code, it does not. I am not sure what more to explain. Please help me Steve I am attaching a zip file. I hope it gets through.

The problem is due to the values of Sensors, TestStrips and SampleNumber
being strings; what you want is for them to be lists, as in the assignments
you commented out. And since the data from the file is read in as strings,
you have to cast the elements of the Sensors and TestStrips lists to
integers, since you want the numerical values. The following code does the
job:
Sensors = []
TestStrips = []
SampleNumber = []
x = 1
SensorNumber = input("Enter senaor number: ")
with open("_EXCEL-FILE.txt", 'r') as infile:
for lineEQN in infile:
if (lineEQN[0:1]== "."):
SN = lineEQN[44:48].strip()
if (SensorNumber == SN):
SN = x
SampleNumber.append(SN)
sv = lineEQN[25:29].strip()
Sensors.append(int(sv))
tv = lineEQN[32:37].strip()
TestStrips.append(int(tv))
x += 1
labels = SampleNumber
Add the rest of your code from the second half to make the desired bar
chart.

The > rest of the wave form logic is probably still of use for that. It may be that there's a fallback audio device that uses the PC speaker on systems that lack even basic audio support in their chipset. But in common practice, Beep() does not use the PC speaker. The "beep.sys" driver in Windows 7+ has no code path that starts a PC speaker beep via HalMakeBeep(frequency) and ends it after a timeout via HalMakeBeep(0), which was the old implementation of "beep.sys" that can still be seen in ReactOS [1]. The HAL (hardware abstraction layer) function HalMakeBeep() is still implemented in Windows 10, but without the connection to an IOCTL in "\Device\Beep", or some other installed device driver, there's no way for user-mode code to make a beep with the classic PC speaker. In Windows 7+, the beep device's IOCTL_BEEP_SET function is just a relay. It's implemented by searching for and completing a queued IOCTL request from a task in the user's session (i.e. an inverted callback from kernel mode to user mode). This task, which is scheduled to run at logon in every interactive session, executes the "PlaySoundSrv.dll" module in an instance of "taskhostw.exe". Upon completion of its queued IOCTL, from which it gets the beep frequency and duration, the sound server generates the requested beep waveform and plays it on the default audio output device via WinAPI PlaySound(). Notably, the "beep.sys" driver doesn't support manually starting the sound-server task in the user's session. So if one terminates the "taskhostw.exe" process that's hosting "PlaySoundSrv.dll", WinAPI Beep() will no longer work. To get it back, the "\Microsoft\Windows\Multimedia\SystemSoundsService" task has to be restarted manually. --- [1] https://github.com/reactos/reactos/blob/master/drivers/base/beep/beep.c#L295 -- https://mail.python.org/mailman/listinfo/python-list -- https://mail.python.org/mailman/listinfo/python-list

matplotlib questions
I am trying to modify the "Bar Graph Demo" at https://matplotlib.org/stable/gallery/index.html, Lines, bars, and markers but the more I experiment and change the code, the more messed up it becomes. I have the demo code working. This is my second attempt. I guess I accidentally got my first chart working but this second one, not so good.

[tkinter] question about correct use of validation
for determine the maximum number of characters in an entry
I have read several interpretations for the solution of the problem, but
I wanted to find an alternative way (for convenience of the code)
I kindly ask for an opinion on the use of validation in this way.
-
problem: limit number of characters in different entries of a form.
code:
#!/usr/bin/python
# -*- coding: utf-8 -*
from Tkinter import *
class View():
def __init__(self, parent):
self.parent = parent
self.make_ui()
def make_ui(self):
''' create user interface '''
self.id_entry = Entry(self.parent, width=6)
# take out the properties for understanding
vcmd = (self.parent.register(self.maxlength_validate), '%P', 4)
# 4 is my question
self.id_entry.configure(validate="key", validatecommand=vcmd)
self.id_entry.pack()
self.name_entry = Entry(self.parent, width=30)
# take out the properties for understanding
vcmd = (self.parent.register(self.maxlength_validate), '%P', 20)
# 20 is my question
self.name_entry.configure(validate="key", validatecommand=vcmd)
self.name_entry.pack()
def maxlength_validate(self, value, maxlength):
''' function validated for maximum number of characters '''
maxlength = int(maxlength)
if len(value) > maxlength:
value = value[:maxlength]
return (value == ' ')
return True
def run():
root = Tk()
root.title('test')
View(root)
root.mainloop()
if __name__ == "__main__":
run()
The code works well :-) but...
in vcmd i use this:
vcmd = (self.parent.register(self.maxlength_validate), '%P', 20)
# '20' argument is my question, is not default value (is max length of
char, different for each entry... very comfortable for me)
is it all right, according to you, to pass a non-default argument? (no
error from the interpreter)
Without this way I would not know how to pass the maximum number of
characters to the validation function, I can not use one variable
self.--- for each entry ... it would become aesthetically unattractive.
I would not even like to add a textvariable variable because anyway then
I should always pass the comparison value.
thank you in advance
Steve

How do I get a python program to work on my phone?
This is my first message to this forum, I am not sure how to submit it so please correct me if I am not doing this properly. === Being new to python as of a year ago December and have extensive programming experience: C++, VBasic, HTML etc... I installed Python and wrote a program that documents my blood readings enough that my A1c results went from 9.1 to 6.4 in about two months and have had low numbers since. I now want to run it on my MotoG phone. The program accepts keyed in data and will access two text files to keep data and I would like to have the program chime my phone to remind me to take the next reading.

Python program to phone?
I have written my first python program (600 lines!) to help control my blood sugar and it has been so successful that my A1c dropped form 9.3 to an impressive 6.4. It will be much more useful if I had it on my phone. (MotoG, Android) The .py file reads/writes to two txt files. About a year ago, I installed Kivy and managed to transfer the "Hello World" app to my phone and it worked. I am not on a different computer and believe that I got all the way through the installation but I do not see how to invoke it. I am sure that I can go through the tutorial again and use my program instead. How do I figure out what is wrong and might there ne a better way to get the program onto my phone? Steve P.S. Yes, I tried to post this about two weeks ago but could not seem to respond to the replies I received. I could contact one or two individuals but apparently not the masses.

Why am I asking? Today's code review included a for...else structure. I've rarely seen such a thing, and even knowing it exists, cannot recall ever using it! The coder intended to implement the scenario (above) but did not realise that the else-clause means 'execute if the loop ended without using break'. She thought it meant 'if there's nothing in the iterable, execute the else clause' (per if...then...else... ie the two clauses are mutually-exclusive*) - which one assumes is the reason why the BDfL is claimed to have said it should never have been implemented (this way).

The names all appear in a list, so the most frequent use-case is trivial: print( "And the winners are:" ) for name in list: print( name ) but, if no-one actually qualifies, a warning message is required, eg print( "Sorry, no-one is eligible" ) Possible solution: To make anything more than the trivial case readable, I think I'd put the list processing into one function, and the exception into another (except that this case is so trivial), ie if list: process_list() #the heading and for-loop, as above else: print( "Sorry... Others wanted to add a semaphore/flag inside the loop to indicate if it was executed at least once. Yes, could even use the else clause then! The ideas went (rapidly) down-hill from there...

A limit to writing to a file from a loop?
My program reads from a text file (A), modifies the data, and writes to another
file (B).
This works until I reach about 300 writes and no more lines are written to file
(B).
I had to create a Counter and increment it to 250 when it gets reset.
Upon reset, I close the file (B) being written and reopen it for append.
Then it accepts the entire list of lines of data.
Bizarre?
CycleCounter += 1
if CycleCounter > 250:
CycleCounter = 1
DateReadings.close()
DateReadings=open("Date-ReadingsAndDoses.txt", "a")
DateReadings.write("{0:15} {1:>8} {2:>8} {3:>8} {4:<2} {5:>8}

DateReading.close()
I also tried to append but that did not work either.
Interestingly enough, this is a feature that really has no real purpose in the

RE: A limit to writing to a file from a loop?
Very good points. In short, I wrote two test programs.
One to write 400 lines of data into a file.
Another to read it, modify it, and write to a new file.
With some questionable spacing in the final file, I was able to read/write 400
lines of code disproving my original suspicion. Back to the drawing board but
at least I can write all the lines using my work around in the original
program. The question is why is there a difference?. I will post again if I
find something.
The plot thickens.

Perhaps part of the transfer to email, but won't this code only output once per
250 records, cf 250 records per cycle?
Some suggestions:-
Test one: Prove that there is valid input
- is the code successfully reading more than '250' records?
Test two: Check the actual data
- is there anything strange about the '250th' record (the one that first
exhibits the problem)?
Test three: Prove that it is not some Python<->file system issue
- what happens if the first input record is written (to a 'junk file')
250+ times?
Test four: (possibly unnecessary after the above) Disprove a size issue
- what happens if you output a simple/hello world string (of the same
number of bytes) instead of the incoming data, 250+ times?
Report back. If there are still problems, please show the original code
and exception report...

New rules for scope in a function?
I have been programming for more years than I want to admit and believe that I have a good understanding when it comes to the Scope of Variables when using functions. Are the rules different when using python? It looks as if I have to pass all variables to and from the function before it works. Are variables used in the main program not also visible for use within the function? Do these variables have to be declared as global? Steve Footnote: Ultrasound Technician Asks Pregnant Woman If She’d Like To Know Baby’s Name -- https://mail.python.org/mailman/listinfo/python-list
RE: New rules for scope in a function?
OK, I wrote:
x = "A"
print("x = " + x)
def f(y):
print("x= " + x + " y= "+ y)
f(x)
and it worked, inspite of what I was seeing in my own program.
How quick I am to blame Python. (:
When I isolate my function that stumped me, I will post it.
Thanks.

Functions in Python have access to everything in the surrounding scopes,
usually a module. Any name that's ever *assigned to* in the function
(including its parameters) is local to that function, and anything that you
look up without assigning comes from the outer scope.
x = 1
def f(y):
print(x, y)
This function is happily able to see its own parameter (a local) and the
name from outside it (a global). It's also able to see the "print"
function, which comes from the builtins - that's just another scope.

Is your .py file represented with the python icon? If not then you probably have a path problem. You can check to see if python is working if you copy a .py file into the same folder where python.exe exists. If you can execute the .py file from that folder then and not elsewhere, it is probably a path problem. >From my bad experience installing Python, apparently the installation did not handle the path modification very well. I had to add the python path into the environment manually. To check this, open a CMD screen and enter "path" as a command. Check to see if the path to Python is listed. I struggled with this in my first installation of Python until I learned how to manually modify the environment path. I had to install python on a second computer but did not remember what magic I had to do to get the system to remember where the python.exe was located.

I suspect there isn't any deep reason for it, rather it's just something that fell out of the implementation, in particular the decision to optimise local variable access in functions but not other scopes. When compiling a function, the compiler needs to know which variables are local so that it can allocate slots for them in the stack frame. But when executing a class body, the locals are kept in a dict and are looked up dynamically. The compiler *could* be made to treat class bodies the same way as functions in this regard, but it would be extra work for little or no benefit. Most code in class bodies just defines new names without referring to anything else in the same scope. -- Greg -- https://mail.python.org/mailman/listinfo/python-list -- https://mail.python.org/mailman/listinfo/python-list

Dear Squeak, sorry, Dear Steve,
Back in the ?good, old days when we used to walk alongside a mainframe CPU
whilst it cogitated, we would often use the BEL character to alert us to job
completion (and meantime bunk-off to go have a coffee, cakes,
...) - more seriously, it alerted telegraph and telex operators to an incoming
message (you can still hear similar "beeps" on some emergency-worker radio
systems, NASA moon mission video-replays, etc).
In the grips of nostalgia, I tried to make it work using the REPL, and failed,
but first...

The BEL character was included in the ASCII standard as chr(7)*. Back in
those days, the rest of the world didn't exist - the "A" stands for
"American". Accordingly, the huge advance was that we would be allowed
to use lower-case letters, instead of all-caps (capital letters). Using
French accents or German umlauts (etc), anything beyond the "standard"
26-letters of "the" alphabet, would have been infra-dig to a well
brought-up, clean-cut, American boy ("truth, justice, and the American
way"*) - excepting that he wouldn't have understood the term, because
didn't know of any other language than English. This problem was
acknowledged and solved with Unicode. Viva Python 3!
Before you laugh, perhaps in disbelief that at one time computers ran
exclusively in upper-case, take a closer look at ASCII, because even
then there was no "$" or "£", only a generic currency symbol, "¤". What
were they thinking? Simple: computers worked with numbers - why
clutter-up the place by adding pesky letters, labelling 'answers', and
stuff like that?
Whilst we have protocols or understandings in Python, eg a file simply
ends, there is no need for any special indication or code; back in those
?good, old days there were a number of different ways to encode
characters AND to indicate other features of a file. Accordingly, the
"II" part of ASCII - Information Interchange.
So, it was not merely a character set in terms of an alphabet, but by
standardising some universal 'understandings' made "interchange"
possible between computer systems (without which the Internet would
never have become a possibility!). We knew these non-alpha components as
"control characters". They still exist in various forms today - I was
helping a Network Tech revise for his exams, and we ran through the
exchanges necessary to establish a computer on a network using DHCP, and
instead of "right" or "correct" I joked with him by saying "ACK" (and
later, when he made a mistake "NAK") which really made him blink!
The really 'fun' ones today (because there is a difference between Linux
and MS-Windows, ie we've lost the "standard") are "carriage return" (the
process of pushing a typewriter's "carriage" (roller holding the paper)
from the (right-hand!) end of one line all the way to the left again),
"line feed" which was the second half of the typewriter process, when
you first pulled the big handle at the top-right of the machine, it
rolled the paper upward (normally) one line - sometimes called "New
line". Thus "CR", "LF", and often "CRLF", and "NL". (why have two codes
to perform what is (now!) one action?)
"BEL" is one of those "control characters".
If you are familiar with Python's chr() and ord(), you will remember
that characters can be represented both as strings and as integers (in
the case of ASCII, one character occupied one byte; but now that Python
3 uses Unicode, the one-to-one is no longer necessarily true). Thus
control characters can be expressed in either representation*. In the
case of BEL, my elephantine memory immediately recalled it as 7! As if
that wasn't enough, Python also has its set of string literals and
escape characters*.

And if it's not clear from the subject line that it _is_ something somebody knows/cares about, then that somebody is unlikely to read the body of the message. Subject lines like "help me please" or "Python doesn't work" or "An I connected here" are likely to be ignored by most of the people who probably know how to help.

Seeking to convert a py timer app for my Moto E6
I am looking for an app for my Moto e6 android phone that will accept a number
of hours and then count down. Once the hours have been executed, it will
quietly beep every minute until I cancel the app. This is to remind me (and
keep on reminding me) when to take my insulin.
It has been written in python but I do not know how to convert it to an app. I
wonder how much of the python code will still apply. When I was into this in
the past, I installed Kivy and was able to finally generate a "Hello World" app
and managed to get it to my phone. Then life called me back to reality and I
lost track of what I was doing for a few years. )-: I doubt I can go through
that installation and learning curve again.
It works on my computer but I have projects that interfere with the alarm.
This is why I would prefer to have it on my phone.
I appreciate any assistance you can provide.
Steve
I attached the py code but wonder if it will carry with the message. It is
about 100 lines of code but that includes a few ops and whistles that are
probably not needed in the app.
There's 99 bugs in the code, in the code.
99 bugs in the code.
Take one down and patch it all around.
Now there's 117 bugs in the code.

Questions: - is the second program kept in the same directory as the first, or somewhere else? - by "call" do you mean "import", or... If the program and the data files are in the same directory, then you will have noticed that there is no need for absolute addressing, ie open( "file.in" ) not open( "/home/me/Projets/this/file.in" ) The same applies to import-s. From program_A we can import program_B in the same directory. No need for absolute paths, anywhere! That is to say, Python works happily with the concept of the "current working directory", and when no absolute-path is provided assumes 'this directory' - or if a non-absolute-path is provided (doesn't commence with "/", in the case of Posix) prefixes the path from 'this directory'. Yes, there are many caveats beyond such a simple explanation, but that should be enough to get-going. Keeping 'everything' in the single directory, and always executing from there, should enable migration. -- Regards =dn -- https://mail.python.org/mailman/listinfo/python-list -- https://mail.python.org/mailman/listinfo/python-list

RE: Updating a variable problem.
How is MSN a new variable? It is not intended to be.
If line 8 is commented out, it is printable in all three locations.
If line 8 is not commented out, then MSN in the previous line is determined to
be undeclared.
It looks as if I am not allowed to change the contents of the variable MSN.

Subject: Re: Updating a variable problem.
I don't know your exact meaning of fail. But as much as I can say there is a
new variable MSN being declared in the function that is only seen locally that
is inside the function. Now python sees this and probably says variable used
before assigning. You might try declaring a global msn in the function again.
And then changing msn after the print statement. Also this error occurred
because python first searches the variable in the local scope which is absent
earlier and so it searches for the variable in the global scope where it is
present and so no errors are raised.

Save-to-file code not quite working completely
I have a file containing specifications. My .py program can read and
manipulate the data but I cannot seem to get it to update the original file
properly.
The code is simple and works except that the original line remains in the
file after the new updated one has been added.
My code:
===
import fileinput
import sys
def ReplaceLine(file,searchExp,replaceExp):
for line in fileinput.input(file, inplace=1):
# if searchExp in line:
line = line.replace(searchExp,replaceExp) #.rstrip()
sys.stdout.write(line)
NewLine = "MSN Monitor Serial Number: 1-T4464 ##
\n "
ReplaceLine("Specifications.txt","MSN", NewLine)
print()
PauseHere = input("Paused")
=
The text file:
1 MSN Monitor Serial Number: 1-T4464 ##
Monitor Serial Number: -T4464 ##
2 TLN TestStrip Lot Number: 45001 82624 ##
3 SED Strip Expire Date: 2021-02-28 ##
4 SEC Sensor Sequence Code: 68 ##
5 SCN Sensor Code Number: F95 ##
6 SEN Sensor Serial Number: 0M000APJYWM ##
7 SDE Sensor Date to Expire: 2020-12-31 ##
8 SDN Sensor Day Number: 1 ##
9 DTD Data Time Date Fri Aug 07, 2020 21:30 ##
=
That second line shown was the original line for MSN. The replacement line
should have replaced the original line not just get added to the file. It
should have been replaced. What is in line 2, should have "1 MSN" at the
beginning but that somehow disappeared.
So close, so simple...
How do I fix this?

That's how the .replace method works. It searches for matches and replaces any
matched portion(s) with the replacement string. It leaves the rest of the
string alone.
You told it to replace all occurrences of "MSN" with something else. It did
that. It didn't make any other changes.
What do you want it to do?
If you want it to replace the line that contains "MSN" with the new line, but
retain the number, then you need to write code to do that.
Something like this:
if searchExp in line:
# Retain the number from the line.
line = line.split()[0] + ' ' + replaceExp

RE: Python Pandas split Date in day month year and hour

If you are reading it is as a line into python, then it is a tuple and can be
parsed accordingly:
Nb = YourdataLIne[0:1] #Line Number
Yr = YourDataLine[3:7]#Year
Da = YourDataLine[9:11] #Day
Mo = YourDataLine[13:14] #Month
Hr = YourDataLine[16:18] #hour
Mn = YourDataLine[20:21] #minute
Sc = YourDataLine[22:23] #second
Use
Print ("Year = " + Yr + ", Month = " + Mo + ", Day = " + Da + ", Hour =
" + Hr)
You may have to adjust the numbers depending on how the line is read.
Is that what you want?

RE: How do I use the data entered in a form?
The only thing I can add to that program as far as errors go is that "SR is
Not Defined" after the program focus is outside of any def in the last line
or two. Is there any location where I should place "return (SR)" or a
"global SR"?
I take it that "fetch" is not an inside command or reserved word. The code
is everything what was posted. Nothing was indicated in the comments that
any code or def was missing.
I commented it out because it was causing the program to dump out preventing
me from exploring the error or developing code for other purposes. Maybe I
don't need it.
Still the value for SR does not seem to be visible outside any of the def
calls. The system reports that "SR is not defined" at the end of the file.

[Always tell us how your code fails, please. If there's an exception include
it and the complete traceback in your post.]
In this case you probably get a NameError because 'entries' is a local
variable in makeform(). In the global namespace the person you copied the
code from used 'ents' -- so you have to either use ents, too,
> if __name__ == '__main__':
>root = Tk()
ents = makeform(root, fields)
...
SR = ents['Sensor_Reading'].get()
or rename it
> if __name__ == '__main__':

entries = makeform(root, fields)
...
SR = entries['Sensor_Reading'].get()
> # root.bind('', (lambda event, e = ents: fetch(e)))
> #"fetch not defined" reported here
Again, the author of the original code probably defined a fetch() function;
if you want to use it you have to copy it into your script.

Yes, the form/window now closes properly.
Removal of sys.exit() and inserting window.destroy() cleared up the exiting

RE: How do I pull the updated information from a tkinter form?
OK, I was closer than I thought.
Two weeks ago, the concept of tkinter and these forms were totally new to me
as well as, about two days ago, python list was totally new too. I somehow
thought that "window.mainloop()" was supposed to be the last entry in the
function, silly me...
I did not think of returning the list.
Thank you, now it is back for another 30 hours of continuous programming...

Ok, I think I ran into this about a year ago when this was suggested back then.
I entered “pip install pandas”

Then it tells me “Installing with “Miniconda” (huh? Huh?)
Then “Installing from PyPl which is what I used to get the same page that is
telling me all this…
ActivePython, then finally Linux which I am not using.
Ok, then I see:
Installing from source
See the contributing guide for complete instructions on building from the git

create a pandas development environment.

Audacity and pipe_test.py
I am trying to adapt this short file to be used for simple control of the
Audacity audio recording program.
I can get the following does to work:
do_command("Record1stChoice") #Creates a new track and starts
recording
do_command("AddLabel:") #Places a label in the label track
do_command("Stop") # stops the recording
But not this one:
do_command("SetLabel:Label='1' Text='Hello' ")
This is supposed to place "Hello" into the label.

RE: Audacity and pipe_test.py
I used the line you supplied but trying it again, I began to solve the
problem through a series of accidents and errors. As it is, apparently the
Pipe_Test.py has some peculiar features.
>The first is that it will not tell you anything about errors, even whether
or not there is one.
>The commands are space-delimited so Text=Hello is not the same as Text =
Hello even if you have the quotes.
>It tolerates no variables. Label=X, if you have X in a loop, will always
have the value of text X and not a changing number. As a matter of fact,
since Label has to have a numeric value, and seeing X will place the value
of label to be the default of 0.
So, yes, placing the 1 in the line and no spaces, it worked. I was able to
send text to the Label.
One thing I would really appreciate is getting the line as follows to work:
do_command("SetLabel:Label=T Text=ThisList[T] ")
which it a total violation of what I described previously. (-:
The object is to pull the text out of ThisList and increment by looping on T
to populate the labels.
Unfortunately, road bump may well put the kibosh on my project
But I can dream, can't I?

As I interpret

is identified by an integer, not a string. Try
do_command("SetLabel: Label=1 Text='Hello'")

Your line worked except that I used copy/paste to place it in the program.
I kept on getting something like "improper indentation or tab" and pointing
to the end of that line. I guess hidden characters were imbedded and when I
deleted all spaces before and after the paste, then placed them in again,
those hiddens went away.
Also, this language certainly does not like spaces at all except where IT
wants them. The values for ThisList[T] entries were two words, words with
spaces between. No go I removed spaces and replaced them with - where I
wanted them, and it is working really nicely.
My time.sleep(60) or the do_command("'Start Time'=0, 'End Time'=150") lines
do not seem to work unless they are immediately after the Record1stChoice
instruction. This means that placement of the labels happen after the track
is recorded and before the recording is stopped. I can live with that
Now I am going to see if I can name the label track and the recording

You are correct. I use the py timer to pause the commands being sent to the
pipe. There seems to be something fluky about that too. It looks as if
when I have four or more do_commands, it doesn't run as a timer. Takes more
scrutiny...
I am not sure how I lost the entire Audacity command for the Audacity time
control. Still, I need a timer in there somewhere.

them as comments to document the end of the operations. It makes it easier

Most likely your source had a series of spaces, my post had a
leading .
In Python, a is counted as EIGHT spaces, even if an editor
only moved in by four spaces.
Python uses indentation to indicate the block structure of the
language
-- you'll note there are no { } (C or Java), nor ENDIF, ENDFOR, ENDWHILE
statements.

If this is in response to my /first/ post, I forgot to include the '
'
delimiters around the string argument. That meant the command you were
sending to Audacity was seeing three or more parameters, not two. Python
didn't care at that point. If you have the ' ' in place, then Audacity is
the application that is complaining.

The first does nothing for Audacity processing -- it only blocks the
Python script itself. And you haven't provided the Audacity command
completely -- since I can't find that on the script reference page.

Takes more scrutiny... time.sleep() is not a "timer" per se. In most implementations it is a blocking call to the operating system; the OS suspends the task and gives the CPU to another task until the requested delay expires, after which the task is placed onto the "ready queue" to /eventually/ continue running. In a system with lots of high priority tasks, that "eventually" could be a long time.

The problem is that since they're comments, the compiler can't warn you when there's a mistake. After the code has been edited a few times, they will end up being wrong and misleading. If you can't see the structure of the code by looking at the code, then you're doing something wrong. Fix the code (or use a better editor). Adding comments to try to clarify the flow of poorly structured code just ends up making the problem worse later on when the comments are wrong.

Problem saving datetime to file and reading it back for a calculation
I would like to use the line: HoursDiff = int((d2-d1).total_seconds()/3600) to determine the difference in hours between two timedate entries. The variable d2 is from datetime.now() and d1 is read from a text file. I can save d2 to the file only if I convert it to string and, at a later date, it gets read back in as d1 as string. The variable d1 as string will not work in the HoursDiff statement. To me, it looks like a problem in formatting. How do I fix this? Steve -- https://mail.python.org/mailman/listinfo/python-list
RE: Problem saving datetime to file and reading it back for a calculation
Thanks for the response.
I must have spent hours looking on-line for a method to treat datetime
variables yet not one site mentioned the "pickle" module you indicatged. I
did, however solve my problem. It may be a kluge but it seems to work.
I learned that I cannot use print() to display the value of datetime but
once I saved it to a file, I could see it. If I used "d3 = d2.isoformat" it
could be sent to a file with a write statement. Apparently, it gives a
write/read format and places a T between the date and time as a separator.
In trying to read it back into the program and work the calculation, I had
to replace the T with a space and some formatting. It all worked.
#===
LBD = "LBD"
d2 = datetime.now()
d2i = d2.isoformat()
with open("TimeDate.txt", 'r') as infile:
for BottleInfo in infile: # loop to find each line in the file for that
dose
BottleInfo = BottleInfo.strip()
if ((BottleInfo[0:3]== "LBD")):
BottleData = BottleInfo[0:43].strip()
BottleDataA = BottleData[4:14].strip()
BottleDataB = BottleData[16:30].strip()
BottleDataC = BottleDataA + " " + BottleDataB
print("BottleDataC = <" + BottleDataC + ">")
# I guess I could have searched for the "T" and replaced it.
print()
d1 = BottleDataC
import datetime
dto = datetime.datetime.strptime(d1, '%Y-%m-%d %H:%M:%S.%f')
dti = dto.isoformat()
HoursDiff = int((d2-dto).total_seconds()/3600)
print("HoursDiff = " + str(HoursDiff))
print()
TimeDateInfo=open("TimeDate.txt", "a")
TimeDateInfo.write("{0:>5} {1:>25} {2:>5}\n".format (LBD, d2i, HoursDiff))
TimeDateInfo.close()
# ===
Granted, there may be other ways to do this but I actually enjoy the
exploration...
Still, I would like to see other methods.

Python's "pickle" module provides support for storing (most) objects to
files and read them back.
