Hi,
I suppose my question in general is goofy to native python programmers. I'm
originally a C++ programmer and I have a hard time not relating iterators in
python to iterators in STL lol. What I was actually trying to accomplish was
to iterate over 2 iterators using 1 for loop, however I found that the zip()
function allows me to do this quite easily:
list1 = [1,2,3]
list2 = [4,5,6]
for i1,i2 in zip( list1, list2 ):
# do something here...
In one of my earlier threads in this group someone had ended up using zip().
After reviewing that thread again I found that I could also use it to solve
this problem as well. Sorry for lack of details. Thanks for everyone's help.
