Hi there,
I can't explain my experience with what I like to call 'parallel
assignment' (tuple/list assignment) inside 'for-in' loops and list
comprehensions:
1)
[f + g for f, g in (1, 2), (3, 4)]
[3, 7]
2)
x = 'ab'
y = 'cd'
[f + g for f, g in x, y]
['ab', 'cd']
3)
f, g = '123', '456'
f
Once you get used to them meta-classes are very useful. In fact I
have
never built an industrial size OO system yet that did not use meta
classes somewhere in the design...
Speaking of that, would you happen to know a good
tutorial/introduction to metaclasses in Python?
Nope, but it
I'm not sure but from the docs it sounds like os.wait() would
be called once for each child also, as
If you don't specify a pid os.wait should return as soon as *any*
child process terminates. Which is why it returns the pid - to tell
you which child died...
At least that's what I'd expect

You're probably confused about what's being assigned to what inside the
comprehension. Maybe this will clear it up:
Thanks. I realized this mistake right before you replied. Yup, the
coincidence of my test cases threw me there.
By the way, what's a good way to reply to specific subjects and
quoting when using the mailing list through g-mail here?

In a program that I'm writing in Tkinter, I wanted to know how to
animate objects. I have three buttons in the beginnig, all in the
center. I wanted to know how to, when the user clicks one of them,
make them small and move to a top corner and then have a text box
appear where they were.

Hello all! I am trying to pass a variable to my re.compile string (see
broken example below). Is something like this possible? Thanks!

if match.search(line):

Hi Tom,
Ah, I think
I am trying to create a box on the graphics window which asks a user

Unfortunately at this point I'm rendering the text, not printing it

Thanks!

Is it that if you use while 1: you create a recursive function? Hope I

No ...
Remember how functions can call other functions?

Add two integers together.
