Python Python Collections (Retired) Tuples Combo

Quick question about the Combo Challenge

After spending a good amount of time I was successfully able to solve the Challenge using the zip function. However, I don't remember ever covering the zip function in the video lectures. So I am left wondering if there was another intended solution that I was supposed to use. Thanks for the help in advance.

Great, I tried something very similar to that but I think I wrote something closer to "for i in a:" I thought Python steps through the lists using the index number, but my version was too specific to one variable. I can see how the version you used made i into a number that was independent of either variable. Thanks for the help.

Using zip was clever and a good application of research. I'm glad it passed the challenge, sometimes only the expected method will pass even if others work.

If I recall correctly, my solution (not being aware of zip at the time) was something like this:

:warning: SPOILER ALERT

def combo(a, b):
    newlist = [];
    for i in range(len(a)):
        newlist.append((a[i], b[i]))
    return newlist
