Hi all,
I'm pretty new to Python (a little over a month). I was wondering -- is
something like this:
s = re.compile('whatever')
def t(whatnot):
return s.search(whatnot)
for i in xrange(1000):
print t(something[i])
significantly faster than something like this:
def t(whatnot):
s =
Thanks for all the answers on this. (And, sorry the lousy Subject line; I
couldn't think of a better one.)

Here are a couple of functions that I feel stupid for having written.
They work, and they're pretty straightforward; it's just that I feel like
I must be missing an easier way to do this...

Nope. :-)

Look at this -- from Python 2.5.1:
>>> a = [1, 2, 3, 4, 5]
>>> for x in a:
... if x == 3:
... a.remove(x)
... print x
...
1
2
3
5
>>> a
[1, 2, 4, 5]
>>>
Sure, the resulting list is correct. But 4 is never printed during the
loop!
What I was really trying to do was this:
apps =

Sorry. I was just fascinated at the turns it was taking. But the first
answer was fine for me:
for name in apps[:]:
etc.
Thanks all.

This is proving to be a recurring problem for me.
First, I used the save() method of a Python Imaging Library "Image"
object to write directly to the "wfile" of a BaseHTTPRequestHandler-
derived class:
pic.save(self.wfile, 'JPEG')
Worked great in Linux, barfed in Windows. I had to do this

I think a more Pythonic way to write this, in general, would be:
while (1) {
char *tmp = fgets
So, basically what I'm doing is this:
window1 = Tkinter.Tk()
...
window1.destroy()
...
window2 = Tkinter.Tk()
This works well in Linux and Mac OS X (and the PyGtk equivalent works on
all platforms), but in Windows XP, the second window comes up without
focus. (I have to click on it to focus it.

The only gotcha I see is that you won't want to go back to doing it in C.

python.exe and pythonw.exe are both Windows executables. There are no non-
Windows executables in a Python for Windows package.
python.exe is used for console apps or interactive sessions.

py2app bundles Python itself into the app, right? I wonder, is there no
way to create an app bundle that relies on the existing installation of
Python, since OS X already comes with Python? I have a

Thanks. I tried Platypus, and it's close to what I want. But I still

Thanks. I see that it* avoids the issue with Tk starting in the

In fact, it looks like the bundlebuilder
