Loop in a loop?

[Sacred Heart]

Hi,
I'm new to Python and have come across a problem I don't know how to
solve, enter com.lang.python :)

I'm writing some small apps to learn the language, and I like it a lot
so far.

My problem I've stumbled upon is that I don't know how to do what I
want. I want to do a loop in a loop. I think.

I've got two arrays with some random stuff in, like this.

array1 = ['one','two','three','four']
array2 = ['a','b','c','d']

I want to loop through array1 and add elements from array2 at the end,
so it looks like this:

one a
two b
three c
four c

I'm stuck. I know how to loop through the arrays separatly and print
them, but both at the same time? Hmmm.

A push in the right direction, anyone?

R,
SH

Yes, small typo there.

Okey, so if my array1 is has 4 elements, and array2 has 6, it won't
loop trough the last 2 in array2? How do I make it do that?

Thanks, looks like a nice collection of links. I've bookmarked the

Thank you Paul, and everybody else contributing with answers of
various complexity. Although a whole bunch of them was way too complex
for my simple problem, but that's ok.

I now know how to use map and zip, and also learned some tips and
tricks.

Thanks.

All the best,
SH
