How can I fix the code below? Trying to combine 2 iterables in tuples within a list. Thank you!

I was also thinking of using "enumerate" but not sure how to proceed. Thanks in advance!

combo.py 
# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]
def combo(iterable1, iterable2):
    my_list = []
    for i in iterable1 and iterable2:
        my_list.extend((iterable1[i], iterable2[i]))
return my_list

You can't combine two iterables with "and" in a for loop.

But they did say you can assume both are the same length. Perhaps that might help you construct a loop.

Hey Steven, I changed my approach but not sure if I'm in the right direction.

def combo(x,y):
    listing = []
    i = 0
    while True:
        listing[i] = (x[i],y[i])
        i += 1
    return listing

It looks like you have a good idea there, but you don't want your loop to run forever ("while True"). Instead of "True" use a conditional expression that will cause the loop to stop after it does all the items. Also, lists have a method for adding new items that might work better than assigning using an index.
