Pyhon (with wxPython) on Windows' cygwin: can it be done fully ?

Hi Pythonistas, I read diaz's comments with interest, but - in my current configuration, I'm unable to use pdb. I'm developing on cygwin and use wxPython. Consequently, I cannot use native cygwin Python, but my Python is actually the Windows XP Python (i.e., /cygdrive/c/Python25/python.exe). T

end of print = lower productivity ?

I want my productivity back. In Python 2.x, I could easily write things like -- print "f" / print "add" / print "done" -- to a lot of different places in my code, which allowed me to find bugs that I could not track otherwise. When I found out that "f" was not at fault, I could write -- print "g"

Re: initialized list: strange behavior

The issue is exhausted in Python Library Reference, Chapter 3.6, so I should apologize for initial posting. All comments were helpful, though Arnaud and Steve are right that pass-by-anything is off the point. Thanks All! -- http://mail.python.org/mailman/listinfo/python-list
