IDLE is a GUI app running under Tkinters event loop.
I doubt if msvcrt works under Tkinter.
Try running your code in a DOS box.

Tuples are like any other Python collection or sequence.

It won't indeed, because of 3 things:
1. you're trying to sort a tuple. Tuples don't have a sort() method,
use a list instead
2. sort doesn'

The above doesn't allow comma after the first instance

Here is a pyparsing version that correctly recognizes all of your
patterns and returns a (possibly nested) Python list in case
Ah - thanks for the correction! I missed the extra grouping and the
extra spacing ... doh! Sorry about the HTML-formatted e-mail ...
Thanks also for the pyparsing variant as well - I didn't know the

Hello,
If I have multiple Popen calls I need to make, how can I turn these into a

Since you're only interested in the output of the last command on the
pipeline, I don't see a reason to keep track of them all. I'd do
something like this:
def pipeline( *commandlist
If i input the following in python:
var1 = 7
var2 = 9
var3 = 5
args = [var1, var2, var3]
args.sort()
then if if type:
args
the output is
[5, 7, 9]
but i want the output to be
[var3, var1, var2]
is there a function that will output the variable
names in the order they

How about passing a list of pipes?
Then you can access them as pipes[0]

Thanks both for the suggestions! I learned from each!
I believe the small function will work for me. Its simple since I don't
have to track each pipe I open with a variable. I had no idea I could do
that nifty if/then for the stdin, that makes it so easy. :-)
Thanks again!

I should begin by explaining I am not a sysadmin, I'm merely one trying to
use the right tool for the right job, and for my job I believe Python to be
that tool. Here is an outline of what I wish to accomplish, pointers to
modules, tools of interest, etc. would be greatly appreciated... Below each

No, the mapping from names to values is one way. It's pretty easy to
have a value associated with no name, or more than one name

Hello! I'm creating a dictionary called keywords that has multiple entries
each with a variable list of values eg.
keywords[1] = [1, 4, 6, 3]
keywords[2] = [67,2]
keywords[3] = [2, 8, 5, 66, 3, 23]
etc.
The keys and respective values (both are integers) are read in from a file.
For each key,

Thanks Kent, and Evert, and everyone,
I really appreciate the advice on etiqutte and all

thoroughly before any further inquiries and will

Where does the if/else syntax come from? It doesn't
seem to work on my Python 2.4. Is it a new feature in 2.5?

This can be written more succinctly as
keywords.setdefault(key, []).append(value)
or in Python 2.5:
from collections import defaultdict
keywords = defaultdict(list)
