Hello all,
I am trying to convert from bash to python for scripting. What is the
simplest & cleanest way to do the following in python:
#!/bin/bash
for i in `seq 1 1000`
do
my-other-script &
done
wait
echo "all done"
I at first tried os.system("my-other-script &") and os.wait() but this

Hi all,
I'm trying to get a hang of properties. It isn't quite clear to me
what is the best way to make properties differ in subclasses. Some
code snips to show what I've tried:
class A(object):
... def __init__(self): pass
... def prop_set(self): return "I was set by A's method"

In addition to Michael's comments, to bind to a keypress, you just do (eg)
widget.

This is a limitation of Python's nested scopes. You can't assign to a
variable in an enclosing scope. One way to work around this is to use
a mutable value like a list in the enclosing scope:

YOu are welcome, everyone should at least dabble

the fundamentals of programming.

Greetings.
Any comments made by me will certainly not be the
'pythonic' way to do things, but I would like to
make a few comments on the subject, and possibly
weave in a few questions of my own.

break terminates the current loop, which is inside your print_options
function. print_options is called from inside print_options.

I forgot to mention that I am running on a Linux system if that makes any

This is an excellent observation and points to the real problem with the
original question. The problem is that the base class has more features
than some of the classes that will be dervied from it which is usually
