Re: I wrote a free book about TDD and clean architecture in Python
Akkana, yes that is a good idea, even though I expected the LeanPub output to be already the correct one. I'll check with them. Thanks for reading the book, you actually gave me an idea: writing something about adding tests to a project *after* the code has been written. I already wrote a post on it, with a practical example, and this might be interesting. Many people discover TDD after they already wrote some code.

Re: I wrote a free book about TDD and clean architecture in Python
A couple of people asked the link to the post I mentioned, sorry I forgot to add it http://www.thedigitalcatonline.com/blog/2017/07/21/refactoring-with-test-in-python-a-practical-example/ This is just a very simple exercise in refactoring, but I believe it's a good starting point for people who never faced such a task.

What is the difference between "ws.Messagebeep(1)" and "ws.Messagebeep(-1)" ?

Timing problem?
I believe I can see what is happening here but maybe someone can explain least I run into this again. Situation 1: I am using "ws.MessageBeep(1)" to generate a tone through the speakers. I wanted two tones to separate it from other tones that might happen and placed that code a second time in the next line. Sometimes it would not beep, others just one beep. Situation 2" At the end of my program a report is generated and then it calls timer1.py to remind me when to enter the next readings from the lab. It looks as if the report generation is interrupted when timer1.py is called. If I place "time.sleep(1)" between the commands for the beep, I get two beeps one second apart reliably. If I place "time.sleep(5)" between the report generation the call for timer1.py is called then apparently there is enough time for the report to be generated. What is happening?

Re: What is the difference between "ws.Messagebeep(1)" and "ws.Messagebeep(-1)" ?
Assuming ws is winsound, MessageBeep(-1) produces a "simple beep". MessageBeep(1) doesn't seem to actually exist so it might fall back to that same "simple beep". The possible values are -1, MB_ICONASTERISK, MB_ICONEXCLAMATION, MB_ICONHAND, MB_ICONQUESTION, and MB_OK, all of which are defined in the winsound module.

RE: What is the difference between "ws.Messagebeep(1)" and "ws.Messagebeep(-1)" ?
I'm assuming by ws you mean winsound? Check the docs: https://docs.python.org/3.7/library/winsound.html winsound.MessageBeep(type=MB_OK) Call the underlying MessageBeep() function from the Platform API. This plays a sound as specified in the registry. The type argument specifies which sound to play; possible values are -1, MB_ICONASTERISK, MB_ICONEXCLAMATION, MB_ICONHAND, MB_ICONQUESTION, and MB_OK, all described below. The value -1 produces a “simple beep”; this is the final fallback if a sound cannot be played otherwise. If the system indicates an error, RuntimeError is raised. winsound.MB_ICONASTERISK Play the SystemDefault sound. winsound.MB_ICONEXCLAMATION Play the SystemExclamation sound. winsound.MB_ICONHAND Play the SystemHand sound. winsound.MB_ICONQUESTION Play the SystemQuestion sound. winsound.MB_OK Play the SystemDefault sound. -Original Message- From: Python-list [mailto:python-list-bounces+david.raymond=tomtom@python.org] On Behalf Of Steve Sent: Thursday, March 21, 2019 10:00 AM To: python-list@python.org Subject: What is the difference between "ws.Messagebeep(1)" and "ws.Messagebeep(-1)" ?

I'm currently on a shared server hosted by Hostmonster. I don't have root access, so a local install would be my only option. If local install doesn't work or is insufficient, then I would switch to a VPS. Since I'm retired and only a hobbyist in my Golden Years :), a shared server would be sufficient and cheaper, so that is my first choice. Having said that, if I have to go with a VPS (and root access) your information is very helpful. Thank you. -- Tim Johnson http://www.tj49.com -- https://mail.python.org/mailman/listinfo/python-list

If I recall the context from previous discussion, "ws.MessageBeep(1)" creates the same tone that you would get if you had a message box pop up, right? In that case, Windows is probably suppressing duplicates - if there's a tone already playing, it won't play it again. This would be a good reason to switch back to using the PC speaker, as that would actually consume as much time as the beep does. An easy way to check this: >>> t = time.time(); ws.MessageBeep(1); print(time.time() - t) >>> t = time.time(); ws.Beep(262, 250); print(time.time() - t) My prediction is that the first one will take negligible time, but the second will pause for the quarter-second that the beep is taking. Additionally, this would let you play tones of different pitches, to separate them from other tones. Alternatively, if you don't want to use ws.Beep(), it might be best to switch to explicitly calling on VLC Media Player. Something like: >>> subprocess.check_call(["vlc", "--play-and-exit", "some-file.wav"]) which should play whatever audio tone you like. Freely usable sound bites can be obtained from various places on the internet, or you might have some yourself. (If you have "American McGee's Alice", the blunderbuss firing sound makes a great alarm tone. SssBOMss.) ChrisA -- https://mail.python.org/mailman/listinfo/python-list

how to handle response data that is streaming and chunked?
Hello,
I am trying to learn how to do use response library in the least confusing
way possible. My data source is streaming.
The sample I share below looks more complicated that it needs to be. I do
not have enough experience with this to know better. Hence why I came here
for guidance and direction. Comments are very welcome as well as pointers
to reading material. I want to learn this.
I expected that I was going to be able to use the JSON methods such as load
or loads. After all, this is JSON and should be able to slurp into builtin
python objects and data structures, I'd imagine.
Does this mailing list use a paste site or is better to paste code in-line
for future?
Thanks for reading!

This seems like a tedious way to move to forward. That is why I am trying
to understand what my options are for chunked data and hopefully running
the response data through a JSON decoder ring. I want well-known data
structure objects. I believe it to be possible. I just do not know how to
get there from here.
Everybody may agree that doing it this way, and further, extracting this
data from text with regex is the cornerstone of a poor implementation. My

As far I can tell from the docs, calling '.iter_content' with
'decode_unicode=True' will make it decode, so you shouldn't be decoding
it again.
Also, string indexes start at 0, and '.find' will return -1 if the
string is not found.
As you don't need the index itself, you might as well use 'in' instead:
while '}}' in lines:
On the other hand, you're splitting the string, so maybe it would be
better to use '.partition':
before, sep, after = lines.partition('}}'):
while sep:
print(before + sep)
lines = after
before, sep, after = lines.partition('}}'):
Note that when you split or partition on '}}', you'll lose the '}}'
itself if you're not careful, hence the 'before + sep' above.

I am not sure, but have my doubts. Software Collections distributes software in RPM, with pathes hardcoded to /opt/rh/. You may be able to use "alien" to convert the RPM to a tarball that you could untar somewhere in your home directory. The scripts to "enable" a software collections module into your current path would work regardless of install point. Maybe this is faster than compiling from source?

I don't know about RPMs, but it'll most likely be equivalent to what I've done with Debian packages. Advantages include not needing to install the dev libraries for everything, not needing to worry about optimization settings on the compilation (ideally, the upstream packager will use PGO), and some verification that it should work with your libraries. Disadvantages include that there may be paths hard-coded into it (if you build from source, you can tell it to put it in ~/bin), and having to learn how to extract your platform's packages. Often worth it. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
log file
I am running a program and even though the program runs all fine, the log file is missing. I have pasted first few lines of the code. Any suggestions where I maybe going wrong? import os import csv import logging import assertion_design as asd import random #Create and configure logger logging.basicConfig(filename="test_1.log", filemode='w', format='%(asctime)s %(message)s') import os import csv import logging import assertion_design as asd import random #Create and configure logger logging.basicConfig(filename="test_1.log", filemode='w', format='%(asctime)s %(message)s') -- https://mail.python.org/mailman/listinfo/python-list

It's not getting me here, but I am running into a problem using ANTLR's visitors to deal with what kind of storage opcode to use when running into an assignment. I only roughly pondered it in my head but never really looked at the AST Python was generating for clues. But, you see, my cat is hungry and I have to, you know, ... take care of him. A lot.

Do all of these lines actually appear, or is it an accidental
copy-paste+paste?
What do you use to actually record data in the log? eg
logging.info("Informational message")
Any error message from Python?
When you say "the log file is missing" do you mean that there is no such
file, that there is an empty file, or what? Which directory do you run
the code from, and in which directory do you expect to find the log file?

I am thinking--hoping, rather--that you just kind of double pasted there.
Anyways, you needed to specify the logging level in basicConfig:
import os
import csv
import logging
import random
#Create and configure logger
# Check out level=logging.INFO
logging.basicConfig(filename="test_1.log", filemode='w', format='%(asctime)s
%(message)s', level=logging.INFO)
log = logging.getLogger()
log.info("Yay!")
