Hi all,
I have three lists with the same length. Is there any method to loop
the three lists without a loop counter?
Best regards,

Hello,
the zip function?
>>list1 = [1,2,3] list2 = [4,5,6] list3 = [7,8,9] for a,b,c in zip(list1,list2,list3):
.... print a, b, c
....
1 4 7
2 5 8
3 6 9

What exactly do you mean?
Are you trying to loop them together with the same ´count´. "for loop
in zip(1,2,3) kind of thing or something else.
Please either post a more descriptive question, or your current code.

Try zip or itertools.izip:
pyL1 = ['a','b','c']
pyL2 = [1, 2, 3]
pyL3 = ['I', 'II', 'III']
pyfrom itertools import izip
pyfor x,y,z in izip(L1,L2,L3):
.... print x,y,z
....
a 1 I
b 2 II
c 3 III

Maybe you just need this:-)
>>list1 = [1, 2, 3] list2 = [4, 5, 6] list3 = [7, 8, 9] for i in list1+list2+list3:

Davy,
Look at the "zip" function,
<http://docs.python.org/lib/built-in-funcs.html>
Look near the bottom of the page.
Example:
zip([1,2,3], [4,5,6], [7,8,9])
==[(1, 4, 7), (2, 5, 8), (3, 6, 9)]
Cheers,
-M
