Getting the right answer locally but not on the code challenge.

Hi,

This has happened so many times now that I had to ask. I get the correct answer locally when running my code - but when I get onto treehouse and submit my code I get "Bummer! Try again!".

For example:

def combo(a, b):
    my_tuple_list = []
    for k, v in enumerate(a):
        my_tuple_list.append((v, b[k]))
    print(my_tuple_list)

combo([1, 2, 3], 'abc')

gives me: 

python zippy.py 
[(1, 'a'), (2, 'b'), (3, 'c')]

locally which should be correct judging by the commented section on the challenge. But I still get a bummer.

Why?

Thanks.

Hey Tony, You've done a great job with it, you just need to return my_tuple_list instead of printing it out at the end of your function! Keep up the good work! Happy coding! :) -CodyTheCoder

Like Cody says, you need to return the value in the function, not just print it out. I suggest trying/doing this locally instead, so you can grasp the differences of returning and printing:

def combo(a, b):
    my_tuple_list = []
    for k, v in enumerate(a):
        my_tuple_list.append((v, b[k]))
    return my_tuple_list

print(combo([1, 2, 3], 'abc'))

Hahaha, oh my god! Thanks guys for clearing it up - I have been doing coding challenges @ hackerrank for the whole day and night so things went kind of south from there :\ Been sleeping a bit now - so going back at it :D

And I do know the difference; this was just my eyes playing a trick on me :\ Thanks for the answers guys :)

The only reason I give Cody the "Best Answer" is that he was first :) Love the example tho, Kristian :)
