This would be awful when, eg, one adds an argument to the function
definition. It would require edition of the code at two different
locations.
Thanks

Consider the following

>>> for i in l:
... i = i + 1
...
>>> l
[1, 2]
I understand (I think!) that this is due to the fact that in Python
what looks like "assignment" really is binding a name to an object. The
result is that inside the loop I am creating an objec
Hi Jorgen
THanks for your help. I began writing a wrapper around python did (as
Donn suggested), but then noticed that this was due to not having
educated myself on the options you can pass to ps, pidof and top:
running pidof -x and using the 'c' command in top work pretty nicely.
That way I no l

Hello!
This question does not concern programming in python, but how to manage
python processes. Is there a way to "name" a python process? At least
on Linux, if I have two python programs running, they both run under
the name "python"
#pidof program1.py
[empty line]
#pidof program1.py

Thank you all for your great help. One of the few things better than
python is the knowledgeable community around it. : )

Hello everyone
I am faced with the following problem. For the first time I've asked
myself "might this actually be easier to code in C rather than in
python?", and I am not looking at device drivers. : )
This program is meant to process relatively long strings (10-20 MB) by
selectively modifying
Hi Dennis,
Thanks for your help, what is happening is clear now. Just found that
calling curses.raw() lets you get all scan codes.

Hello
I am writing a small app to learn how to use the curses module. I would
like to know how I can get "composite" key presses, eg, Control+Q.
Currently I am looking at the following code snippet:
import curses.wrapper
def main(stdscr):
x = 0
while True:
key = stdscr.getch(
Hello everyone
Consider the following two simple files. The first is my "program", the
other a file holding some global variable definitions and code shared
by this program and a "twin" program (not shown here):

Dear all,
I'm trying to use Python's readline module but I'm having some trouble.
In particular, autocompletion seems to "get stuck" on white spaces.
Please take a look at this code snippet:
import readline
def completer(text, state):
text = text
list = ['a dog', 'artsy']
if len
Thanks, Dennis, that solved it.
Cheers

Dear all,
I just noticed the following behavior when I run
import os
import sys
import readline
histfile = os.path.join(os.environ["HOME"], ".pyhist")
try:
readline.read_history_file(histfile)
except IOError:
pass
import atexit
atexit.register(readline.write_history_file, histfile)
del
Thank you for the pointer. I'll upgrade to 2.4.

I've got several large sets in my program. After performing several
