how to normalize indentation sources
Hi, I have a lot of sources with mixed indentation typically 2 or 4 or 8 spaces. Is there any way to automatically convert them in let's say 4 spaces? Thx, A. -- http://mail.python.org/mailman/listinfo/python-list
deploying big python applications
Hi, let me describe how I do that today. There is standard python taken from python.org installed in a c:\python23 with at least dozen different additional python packages (e.g. SOAPpy, Twisted, wx, many smaller ones etc) included. Also python23.dll moved from c:\windows to c:\python23. This is zipped and available as over 100MB file to anyone to manually unzip on his/her PC. This is a one time step. On top of that there is 30K lines of code with over 100 .py files application laid out within a directory tree. Very specific for the domain, typical application. This again is zipped and available to anyone as much smaller file to unzip and use. This step is per software releases. There is one obvious drawback - I can not separate python from standard libraries easily. So when upgrade to 2.4 comes, I need to reinstall all the packages. In order to address that as well as the Linux port I project following structure: -default python.org installation or one time step on Windows -set of platform dependent libraries in directory A -set of platform independent libraries in directory B -application in directory C This way I can easily port (or just use) entire software under Linux/Unix yet do not have to worry about collecting all the packages evry time I change the platform or the version of Python. I hope I described it well enough. How to achieve it, is there any better solution, or ready one. Please advice. Thx in advance, A. -- http://mail.python.org/mailman/listinfo/python-list

Right under your nose: C:\junk\python24\tools\scripts\reindent.py --help reindent [-d][-r][-v] [ path ... ] -d (--dryrun) Dry run. Analyze, but don't make any changes to, files. -r (--recurse) Recurse. Search for all .py files in subdirectories too. -v (--verbose) Verbose. Print informative msgs; else no output. -h (--help)Help. Print this usage information and exit. Change Python (.py) files to use 4-space indents and no hard tab characters. Also trim excess spaces and tabs from ends of lines, and remove empty lines at the end of files. Also ensure the last line ends with a newline.

redirecting print to a a file

And if the script runs somewhere that stderr is likely to disappear:
prog1 = subprocess.Popen(['prog1'], stdout=file1, stderr=subprocess.STDOUT)
Forgot to mention before that the main motivation is to have the same
code on bot Linux and M$ platforms.
Does subprocess work well on both?
Also how to find out that the 'prog1' e.g. has exited and it is done?
Thx,

__all__ does not work?
This a mm.py module:
_all__=('getsize1',)
size=85
def getsize1():
return size
def getsize2():
return 2*size
I do not know why but getsize2 is not kept priviate?
$ python
Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on
win32

import mm
mm.getsize2()
170
Any ideas?

That's not what __all__ is used for. Try this:
from mm import *
The only name added to your namespace will be getsize1.

Okay, got it. Thx.
