Using the Komodo IDE under XP I often get python.exe has encountered a
problem and needs to close. Running python direct on the same app
gives a list index out of bounds error. Any ideas how to get Komodo to
give the proper error?

Komodo ver 3.5.2, build 227162, platform win32-ix86.
XP SP 2
Python 2.4.2
I did not think to enter the bug as it is so basic - list index out of
bounds. When I run python at a dos prompt python handles the error
properly.
In Komodo, a simple case like this is no problem.
x = [1,2,3]
print x[4]
Thanks - that worked!
Thanks to the other replies also.

I'm trying to write a function that takes an arbitrary object and
method.
The function applies the method to the object (and some other stuff).
I get error Test instance has no attribute 'method'
How can I make this work?
def ObjApply (object,method):
object.method ()
class Test:
I figured someone out there must have written a minimal code size prime
number generator. I did not find one after a bit of searching around.
For primes up to 100 the best I could do was 70 characters (including
spaces):
r=range(2,99)
m=[x*y for x in r for y in r]
[x for x in r if not x in m]

At 58, very nice :-) Building on yours we get 57:
r=range(2,99)
[x for x in r if sum([x%d==0 for d in r])2]

You can save two bytes with
56 - nice catch.
55:
r=range(2,99)
[x for x in r if sum(x%d1 for d in r)2]

[2]+[x for x in range(1,99) if 2**x%x==2]
42 - brilliant!
41:
[2]+[x for x in range(1,99)if 2**x%x==2]
... although it appears Christoph is right that it's not scalable.

Make that 41 and 40.

I have a simple python desktop app with several edit controls and a
couple of buttons. It just does some math. What's the simplest way to
make it a server-side app so visitors to my site can run the app via
their browser?

I must be missing something basic.
Can anyone explain why 'A' does not show on the entry widget?
import Tkinter
root = Tkinter.Tk()
class Col:
Rows = [0]
def __init__(self):
Frame = Tkinter.Frame(root);
Frame.pack (side='left')
self.Rows[0] = Tkinter.StringVar();
Thanks for the quick reply. With your reply and another tutorial I get
it now. I needed self.Rows = ... in the constructor. I find myself
wasting a lot of time with poor python docs. Whatever time Python is
supposed to save I'm losing so far in looking up things. I suppose that
will change as I
None - it was a false impression I got somehow.

Thanks - actually I have some of those books on the way from amazon.
The first couple of days with a new language are always the hardest!
