Court of King Arthur,

I’d appreciate any help you can provide.  I’m having problems passing
command line parameters from Windows 7 into a Python script (using
Python 3.4.2).  It works correctly when I call the interpreter
explicitly from the Windows command prompt, but it doesn’t work when I
enter the script name without calling the Python interpreter.

This works:
python myScript.py arg1 arg2 arg3

This doesn’t work:
myScript.py arg1 arg2 arg3

The Windows PATH environment variable contains the path to Python, as
well as the path to the Script directory.  The PATHEXT environment
variable contains the Python extension (.py).

There are other anomalies too between the two methods of invoking the
script depending on whether I include the extension (.py) along with the
script name.  For now I’m only interested in passing the arguments
without explicitly calling the Python interpreter.


Here is the script:

#! python

import sys

def getargs():
sys.stdout.write("\nHello from Python %s\n\n" % (sys.version,))
print ('Number of arguments =', len(sys.argv))
print ('Argument List =', str(sys.argv))

if __name__ == '__main__':
getargs()


Result_1 (working correctly):

C:\Python34\Scripts> python myScript.py arg1 arg2 arg3

Hello from Python 3.4.2 (v3.4.2:ab2c023a9432, Oct  6 2014, 22:15:05)
[MSC v.1600 32 bit (Intel)]

Number of arguments = 4
Argument List = ['myScript.py', 'arg1', 'arg2', 'arg3']


Result_ 2 (Fail)

C:\Python34\Scripts> myScript.py arg1 arg2 arg3

Hello from Python 3.4.2 (v3.4.2:ab2c023a9432, Oct  6 2014, 22:15:05)
[MSC v.1600 32 bit (Intel)]

Number of arguments = 1
Argument List = ['C:\\Python34\\Scripts\\myScript.py']

As a beginner I’m probably making a mistake somewhere but I can’t find
it. I don’t think the shebang does anything in Windows but I’ve tried
several variations without success.  I’ve tried writing the script using
only commands, without the accouterments of a full program (without the
def statement and without the if __name__ == ‘__main__’ …) to no avail.
I’m out of ideas.  Any suggestions?

Works fine for me with this:-

c:\Users\Mark\Documents\MyPython>assoc .py
.py=Python.File

c:\Users\Mark\Documents\MyPython>assoc .pyw
.pyw=Python.NoConFile

c:\Users\Mark\Documents\MyPython>ftype Python.File
Python.File="C:\Windows\py.exe" "%1" %*

c:\Users\Mark\Documents\MyPython>ftype Python.NoConFile
Python.NoConFile="C:\Windows\pyw.exe" "%1" %*

c:\Users\Mark\Documents\MyPython>set pathext
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.PY

This is set up by the Python Launcher for Windows, introduced in 3.3, 
see https://docs.python.org/3/using/windows.html#launcher, noting that 
shebang lines also work.

Re: Command Line Inputs from Windows

[Ken Stewart]

Chris, Dennis, James, and Mark:

SUCCESS!  Thanks for your suggestions.  It was the registry.  Kudos to 
Dennis.  The data strings for a lot of different "command" keys in the 
registry were missing the %* (percent star) characters.  Thanks Chris for 
the explanation on why the %* string is needed.


Here is a sample key:
S1-5-21-1560217580-722697556-320042093-1000-Classes
   py_auto_file
   shell
   open
   command

The corrected data for the key looks like this:

"C:\Python34\python.exe" %1 %*

I used the 'find' tool in regedit to search for python in the registry. 
There were many hits on the word python but only a handful had data fields 
similar to the one above.  Every instance was missing the %* string.  I 
modified them all.  My script didn't start working until after I'd modified 
the very last one.  Happily, my computer still boots after mucking around in 
the registry.


I haven't yet investigated the launcher suggested by Chris and Mark.  That 
may well be the proper solution.  At the moment it looks like the Python 
installer didn't create these registry entries properly in Windows 7.


Thanks again

Excellent!

Fiddling with Python's setup under Windows is unlikely ever to stop
your computer from booting. Unlike on most Linux and Mac OS systems,
there's no "system Python" that's used internally; Windows itself
doesn't make use of Python. So you should have no problems playing
around with things.

What is this thing you call "American English"? :-) 

I wouldn't want to put an exact number of distinct accents in the USA, but
it's probably in three figures. And it used to be said that a sufficiently
skilled linguist could tell what side of the street an English person was
born on, that's how fine-grained English accents used to be.

There's a joke about how people from certain parts of the US suffer
from "hat attacks" (heart attacks).

English used to include the letter Thorn too. Among others. Little known
fact: at one time, ampersand & (as in "and") used to be included as a
letter of the alphabet

"American English" is the category compassing all of those accents
common to the USA. There are certain broad similarities between it and
British English, just as there are similarities between Dutch and
German; and there are certain commonalities across all accents of
American English, allowing generalizations about the number of sounds
made by the vowel "a". :)

Yes, but it doesn't any more. Icelandic is the only modern language
I'm aware of that retains thorn and eth (eg in "það").

I used to get very confused watching the old westerns.  The child when 
talking about "more" and "paw" wasn't referring to possibly an 
adjective, noun or adverb and a part of an animal, but what we would 
refer to in the UK as "mum" and "dad" :)

Windows 7 - that's part of the story. What version of Python are you

Unable to reproduce:

Is it possible you have another pathlib installed? It's available on
PyPI, maybe you got it with pip - check 'pip freeze|grep pathlib' on
the off-chance. Is your pathlib.__file__ the same as mine?

Is your keyboard broken? There are a lot of missing characters in your
sentences. You're going to have a lot of trouble programming with a broken
keyboard.

As far as sockets, this is a Python discussion group, not Windows experts.
Try googling for more information and see if that helps:

Python 2.7 for which some widgets did not quite work properly ... but that's

But note that if you send 10 bytes into a socket, it could be received
as two chunks of 5, or other strangeness. So you should frame your

way.  There are multiple ways of dealing with this.  Here's one:

Early Americans are easy to satirize since most were
schooled at home by illiterate parents. I believe the
"redneck vernacular" substituted "mother" and "father" for
"maw" and "paw" respectively. Which is not surprising since
most uneducated folks tend to favor single syllable
simplifications of words over their multi-syllable
counterparts.

Widespread centralized free schooling did not exists until
almost the 1900's. Heck, looking back at American history,
the world *SHOULD* be in awe. To go from a rag-tag
illiterate bunch of cowboys, to the worlds most powerful and
technically advanced society (in roughly one hundred years!)
has to be the most amazing transformation in the history of
the human society.

Of course with all success stories, timing and luck had a
little to do with it, but it was undoubtedly the rebellious
and self reliant nature of Americans that made them so
successful. So before you go and spouting off about how dumb
Americans are/were, ask yourself, what greatness has *MY*
country achieved in the span of a century?

surprise - byte in set

[patrick vrijlandt]

Hello list,

Today I was trying to test for occurrence of a byte in a set ...

True
>>> b'b' in b'abc'
True
>>> 'b' in set('abc')
True
>>> b'b' in set(b'abc')
False

I was surprised by the last result. What happened?
(Examples simplified; I was planning to manipulate the set)

In the last case, the set has integers in it.

Try:
b'b'[0] in set(b'abc')

Put float number in message.

[John Culleton]

Here is my last line in a simple program that is a scribus script.
end = scribus.messageBox('Book Spine Width', 'dummy', ICON_WARNING, BUTTON_OK)

This works. Now I want to put a float number called S instead of 'dummy'.
If I just put S in the command I get an error. If I convert S to a string with
SS = str(S)
first and then 
and substitute SS for 'dummy' I get what appears to be the ASCII numbers 
representing the characters, not the characters I want. 

I am a total newbie with Python. Anyone have a suggestion? Can I use a print 
command instead?

The surprise is really that the 3rd test is True not that the fourth is 
False.


First, as should be expected, a byte string is a sequence of (small) 
ints.  So b'b' is a (short) byte string and the set set(b'abc') is 
composed of three ints.  You should not expect your inclusion test to 
return True when testing for a bytes-type object in a set of int-type 
objects.  And that explains your False result in the 4th test.


>>> type(b'abc')

>>> type(b'abc'[0])



But things are different for strings.  You might think a string is a 
sequence of characters, but Python does not have a character type. In 
fact the elements of a string are just 1 char long strings:


>>> type('abc')

>>> type('abc'[0])


You would not logically expect to find a string 'b' in a set of 
characters in, say C++,  where the two types are different.  But that's 
not the Python way.  In Python a set of characters set('abc') is really 
a set of (short) strings, and the character 'b' is really a (short) 
string, so the inclusion test works.


Python's way of returning a 1-byte string when indexing a string 
(instead of returning an element of type character) allows this 
surprising result.


>>> 'abc'[0]
'a'
>>> 'abc'[0][0]
'a'
>>> 'abc'[0][0][0]
'a'
>>> 'abc'[0][0][0][0]
'a'
...


I've never considered this a problem, but a infinitely indexable object 
*is* a bit of an oddity.

apostrophe not considered with tkinter's wordstart and wordend

[ravas]

When I place my mouse over a word (and I press something) 
I want the program to analyze the word.
Tkinter almost provides the perfect option:
self.text.get('current wordstart', 'current wordend')

Unfortunately apostrophes are not considered using wordstart and wordend.
http://infohost.nmt.edu/tcc/help/pubs/tkinter/
Says: 
"For the purposes of this operation, a word is either 
a string of consecutive letter, digit, or underbar (_) characters, 
or a single character that is none of these types."

The easy work around is to highlight the word and use:
self.text.get('sel.first', 'sel.last')

However, it seems like it could be an easy improvement 
if we could include the apostrophe in the list of word characters.
Is it possible that this could be added in an upcoming version of Python -- 
or is this a Tk issue?

I think you just want some string formatting so (untested) either

end = scribus.messageBox('Book Spine Width', '{}'.format(S), 
ICON_WARNING, BUTTON_OK)


or

end = scribus.messageBox('Book Spine Width', '%f' % S, ICON_WARNING, 
BUTTON_OK)


For all the formatting options see 
https://docs.python.org/3/library/string.html#string-formatting or 
https://docs.python.org/3/library/stdtypes.html#old-string-formatting 
respectively.

I think it is.

 does not mention a way to 
configure the set of word chars either:

"""
?submodifier? wordstart
Adjust the index to refer to the first character of the word containing the 
current index. A word consists of any number of adjacent characters that are 
letters, digits, or underscores, or a single character that is not one of 
these. If the display submodifier is given, this only examines non-elided 
characters, otherwise all characters (elided or not) are examined.

list comparison vs integer comparison, which is more efficient?

[austin aigbe]

Hi,

I am currently implementing the LTE physical layer in Python (ver 2.7.7).
For the qpsk, 16qam and 64qam modulation I would like to know which is more 
efficient to use, between an integer comparison and a list comparison:

Integer comparison: bit_pair as an integer value before comparison

# QPSK - TS 36.211 V12.2.0, section 7.1.2, Table 7.1.2-1
def mp_qpsk(self):
r = []
for i in range(self.nbits/2):
bit_pair = (self.sbits[i*2] << 1) | self.sbits[i*2+1] 
if bit_pair == 0:
r.append(complex(1/math.sqrt(2),1/math.sqrt(2)))
elif bit_pair == 1:
r.append(complex(1/math.sqrt(2),-1/math.sqrt(2)))
elif bit_pair == 2:
r.append(complex(-1/math.sqrt(2),1/math.sqrt(2)))
elif bit_pair == 3:
r.append(complex(-1/math.sqrt(2),-1/math.sqrt(2)))
return r

List comparison: bit_pair as a list before comparison

# QPSK - TS 36.211 V12.2.0, section 7.1.2, Table 7.1.2-1
def mp_qpsk(self):
r = []

It's not clear to me that jmf even understands what easygui is intended
to do.  So I wouldn't worry too much about what he says.  So I'd just
ignore what he has to say.  If someone needs a full event-driven GUI,
they can use an appropriate toolkit.  For quick and dirty little
utilities I can see how easygui fits the bill, and being Qt-based is
good news.

By the way, I'm not seeing jmf's emails; I think they are being filtered
at the mailing list level.  I think enough people got tired of his
trolling that they banned him, though on USENET he's still getting through.

You can test them with the timeit module, but my personal suspicion is
that any difference between them will be utterly and completely
dwarfed by all your sqrt(2) calls in the complex constructors. If you
break those out, and use a tuple instead of a list, you could write
this very simply and tidily:

bits = {
(0,0): complex(1/math.sqrt(2),1/math.sqrt(2)),
(0,1): complex(1/math.sqrt(2),-1/math.sqrt(2)),
(1,0): complex(-1/math.sqrt(2),1/math.sqrt(2)),
(1,1): complex(-1/math.sqrt(2),-1/math.sqrt(2)),
}
# QPSK - TS 36.211 V12.2.0, section 7.1.2, Table 7.1.2-1
def mp_qpsk(self):
r = []
for i in range(self.nbits/2):
bit_pair = self.sbits[i*2:i*2+2]
r.append(bits[tuple(bit_pair)])
return r

At this point, your loop looks very much like a list comprehension in
full form, so you can make a simple conversion:

# From itertools recipes
# https://docs.python.org/3/library/itertools.html
def pairwise(iterable):
"s -> (s0,s1), (s1,s2), (s2, s3), ..."
a, b = tee(iterable)
next(b, None)
return zip(a, b)
# Replace zip() with izip() for the Python 2 equivalent.

def mp_qpsk(self):
return [bits[pair] for pair in pairwise(self.sbits)]

How's that look? I don't care if it's faster or not, I prefer this form :)

Help with finding tutors for Python, Linux, R, Perl, Octave, MATLAB and/or Cytoscape for yeast microarray analysis, next generation sequencing and constructing gene interaction networks

*Help with finding tutors for Python, Linux, R, Perl, Octave, MATLAB and/or
Cytoscape for yeast microarray analysis, next generation sequencing and
constructing gene interaction networks*



Hi



I am a visually impaired bioinformatics graduate student using microarray
data for my master’s thesis aimed at deciphering the mechanism by which the
yeast wild type can suppress the rise of free reactive oxygen species (ROS)
induced by caloric restriction (CR) but the Atg15 and Erg6 knockout mutant
cannot.



Since my remaining vision is very limited I need very high magnification.
But that makes my visual field very small.  Therefore I need somebody to
teach me how to use these programming environments, especially for
microarray analysis, next generation sequencing and constructing gene and
pathway interaction networks.  This is very difficult for me to figure out
without assistance because Zoomtext, my magnification and text to speech
software, on which I am depending because I am almost blind, has problems
reading out aloud many programming related websites to me.  And even those
websites it can read, it can only read sequentially from left to right and
then from top to bottom.  Unfortunately, this way of acquiring, finding,
selecting and processing new information and answering questions is too
tiresome, exhausting, ineffective and especially way too time consuming for
graduating with a PhD in bioinformatics before my funding runs out despite
being severely limited by my visual disability.  I would also need help
with writing a good literature review and applying the described techniques
to my own yeast Affimetrix microarray dataset because I cannot see well
enough to find all relevant publications on my own.



Some examples for specific tasks I urgently need help with are:



1.Analyzing and comparing the three publically available microarray
datasets that can be accessed at:

A.http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE41860

B.http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE38635

C.   http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE9217



2.Learning how to use the Affymetrics microarray analysis software for
the Yeast 2 chip, which can be found at
http://www.affymetrix.com/support/technical/libraryfilesmain.affx



3.For Cytoscape I need somebody, who can teach me how to execute the
tutorials at the following links because due to my very limited vision
field I cannot see tutorial and program interface simultaneously.

A.
http://opentutorials.cgl.ucsf.edu/index.php/Tutorial:Introduction_to_Cytoscape_3.1-part2#Importing_and_Exploring_Your_Data

B.
http://opentutorials.cgl.ucsf.edu/index.php/Tutorial:Filtering_and_Editing_in_Cytoscape_3

C.
http://cytoscape.org/manual/Cytoscape2_8Manual.html#Import%20Fixed-Format%20Network%20Files

D.   http://wiki.cytoscape.org/Cytoscape_User_Manual/Network_Formats



4.Learning how to use the TopGo R package to perform statistical
analysis on GO enrichments.



Since I am legally blind the rehab agency is giving me money to pay tutors
for this purpose.  Could you please help me getting in touch regarding this
with anybody, who could potentially be interested in teaching me one on one
thus saving me time for acquiring new information and skills, which I need
to finish my thesis on time, so that I can remain eligible for funding to
continue in my bioinformatics PhD program despite being almost blind?  The
tutoring can be done remotely via TeamViewer 5 and Skype.  Hence, it does
not matter where my tutors are physically located.  Currently I have tutors
in Croatia and UK.  But since they both work full time jobs while working
on their PhD dissertation they only have very limited time to teach me
online.  Could you therefore please forward this request for help to
anybody, who could potentially be interested or, who could connect me to
somebody, who might be, because my graduation and career depend on it?  Who
else would you recommend me to contact regarding this?  Where else could I
post this because I am in urgent need for help?



Could you please contact me directly via email at thomas.f.ha...@gmail.com
and/or Skype at tfh002 because my text to speech software has problems to
read out this website aloud to me?

I thank you very much in advance for your thoughts, ideas, suggestions,
recommendations, time, help, efforts and support.

With very warm regards,

Hi Thomas

This is a reasonably friendly and generally knowledgeable place for python 
related questions.
Feel free to ask your questions here.

If you need help starting programming and python is your chosen medium
there is also a tutors list
https://mail.python.org/mailman/listinfo/tutor.

As for the rest...

Have a vague idea what yeast is
None whatever of cytospace
And probably think a 'microarray' other than what you do

[That was a joke. More seriously...]
Specialized areas of application of python are less likely to find help out here

That being the case, starting out with python needs a focussed approach
- Spend a few days getting into python
- Then worry about applying it to your needs

In your case you are not just starting python
but python perl R octave mathlab linux
In this manner you are setting yourself up for failure unless you have enough 
money to
hire people for all your programming work.

I can tell you that python ecosystem can offer most of what perl, R, octave 
mathlab offer. But for that you have to go beyond core python to things like
scipy, pandas etc.

Fans of perl, R, octave, mathlab will tell you the same for these as well

You may want to start by throwing a 5-sided coin.

Best wishes on your studies

I am currently implementing the LTE physical layer in Python (ver 2.7.7).
For the qpsk, 16qam and 64qam modulation I would like to know which is more

Integer comparison: bit_pair as an integer value before comparison

 # QPSK - TS 36.211 V12.2.0, section 7.1.2, Table 7.1.2-1
 def mp_qpsk(self):
 r = []
 for i in range(self.nbits/2):

 r.append(complex(1/math.sqrt(2),1/math.sqrt(2)))
 elif bit_pair == 1:
 r.append(complex(1/math.sqrt(2),-1/math.sqrt(2)))
 elif bit_pair == 2:
 r.append(complex(-1/math.sqrt(2),1/math.sqrt(2)))
 elif bit_pair == 3:
 r.append(complex(-1/math.sqrt(2),-1/math.sqrt(2)))
 return r

List comparison: bit_pair as a list before comparison

 # QPSK - TS 36.211 V12.2.0, section 7.1.2, Table 7.1.2-1
 def mp_qpsk(self):
 r = []
 for i in range(self.nbits/2):
 bit_pair = self.sbits[i*2:i*2+2]
 if bit_pair == [0,0]:
 r.append()
 elif bit_pair == [0,1]:
 r.append(complex(1/math.sqrt(2),-1/math.sqrt(2)))
 elif bit_pair == [1,0]:
 r.append(complex(-1/math.sqrt(2),1/math.sqrt(2)))
 elif bit_pair == [1,1]:
 r.append(complex(-1/math.sqrt(2),-1/math.sqrt(2)))
 return r


Wrong question.  If you are worried about efficiency, factor out all 
repeated calculation of constants and eliminate the multiple comparisons.


sbits = self.sbits
a = 1.0 / math.sqrt(2)
b = -a
points = (complex(a,a), complex(a,b), complex(b,a), complex(b,b))
complex(math.sqrt(2),1/math.sqrt(2))
def mp_qpsk(self):
r = [points[sbits[i]*2 + sbits[i+1]]
for i in range(0, self.nbits, 2)]
return r
