Yet another split string by spaces preserving single quotes problem
Hi everyone,
I know this question has been asked thousands of times, but in my case
I have an additional requirement to be satisfied. I need to handle
substrings in the form 'string with spaces':'another string with
spaces' as a single token; I mean, if I have this string:
s =This is a 'simple test':'string which' shows 'exactly my'
problem
I need to split it as follow (the single quotes must be mantained in
the splitted list):
[This, is, a, 'simple test':'string which', shows,
'exactly my', problem]
Up to know I have written some ugly code which uses regular
expression:
splitter = re.compile((?=\s|^)('[^']+') | ('[^']+')(?=\s|$))
temp = [t for t in splitter.split(s) if t not in [None, '']]
print temp
t = []
for i, p in enumerate(temp) :
for x in ([p] if (p[0] == ' and p[1] == ') else p.split('
')) :
t.append(x)
But it does not handle colon case.
Any hints? Thanks in advance!

PyDev and multithreaded application debug
Hi everyone, I've just started to use pydev to develop my python application and I'm encountering some problems to debug it. The application I'm dealing with is a multithreaded application; when I try to debug it with pydev, it seems not to be able to handle the execution of multiple threads. The problem is that when the execution reaches a breakpoint in one of the threads, all the other ones don't stop, but they continue their execution. Have I to make some specific settings or am I missing something? Thanks in advance! -- http://mail.python.org/mailman/listinfo/python-list
Re: Dynamic variable creation from string
Thank you all for your replies, first of all my Sum function was an example simplifying what I have to do in my real funciton. In general the D dictionary is complex, with a lot of keys, so I was searching for a quick method to access all the variables in it without doing the explicit creation: a, b, c = D['a'], D['b'], D['c'] and without using directly the D dictionary (boring...). When I talked about nested function I meant both cases Chris, but this is not a really tighten bound. I tried to follow the hints of Chris together with some help by google and used the following code: for k in D : exec %s = D[k] %k That seems to do the trick, but someone speaks about dirty code, can anyone point me out which problems this can generate? Again, thank you for your help! -- http://mail.python.org/mailman/listinfo/python-list
Dynamic variable creation from string
Hi everyone,
in my script I have a dictionary whose items are couples in the form
(string, integer values), say
D = {'a':1, 'b':2, 'c':3}
This dictionary is passed to a function as a parameter, e.g. :
def Sum(D) :
return D['a']+D['b']+D['c']
Is there a way to create three variables dynamically inside Sum in
order to re write the function like this?
def Sum(D) :
# Here some magic to create a,b,c from D
return a+b+c
It is really important that the scope of a,b,c is limited to the Sum
function, they must not exisit outside it or inside any other nested
functions.
Thanks in advance for your help!

Automatic import of submodules
Hi everyone, in my project I have the following directory structure: plugins | -- wav_plug | -- __init__.py -- WavPlug.py -- mp3_plug | -- __init__.py -- Mp3Plug.py ... -- etc_plug | -- __init__.py -- EtcPlug.py Every .py file contain a class definition whose name is identical to to the file name, so in my main script I have to import each submodule like that: from plugins.wav_plug.WavPlug import WavPlug from plugins.wav_plug.Mp3Plug import Mp3Plug and so on. This is uncomfortable, since when a new plugin is added I have to import it too. So my question is, is it possible to iterate through the 'plugins' directory tree in order to automatically import the submodules contained in each subdirectory?

py2exe: executable is slower than code run from the interpreter
Hi everyone, I'm writing a big program (windows 7, python 2.6.6) which includes lots of python libraries (SQLalchemy, PyQt, SocketServer, Matplotlib,...). Now I'm trying to build a stand alone executable with py2exe (0.6.9) and everything works great. The only issue is that the executable seems to be slower with respect to the same code run from Idle. For example, at stratup my program sets up a server and during the execution sends commands to it and waits for reply. In the code case the average time needed to process a given command is 0.24s, in the executable case it raises to 0.30 (times are obviously measured considering the same command). It is really difficult for me to build a small example script to show the problem, so I guess if anyone knows if there are some issues in py2exe that could bring such a performance loss. Any hints is welcome, thanks! -- http://mail.python.org/mailman/listinfo/python-list

SocketServer problem: client hangs trying to reconnect after server restart
Hi everyone! in my script (Python 2.6 on windows 7) I have to set up a SocketServer server and use it to handle external connections.

Hi everyone! I'm writing a python script which uses a C-written dll. I call the functions in the dll using ctypes, but I don't know how to catch the output of the printf which the C functions use. In fact I don't even know if it is possible! I've heard something about PIPE and popen...is this what I need? How can I use them? It is very important for me that I could take the output in real-time. Thanks for the help! Massi -- http://mail.python.org/mailman/listinfo/python-list
