Python Python Collections (Retired) Tuples Combo

Kishore Kumar

Create a function named combo() that takes two iterables and returns a list of tuples. Each tuple should hold the first

My Code:

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

Output:

[(1, 'a'), (2, 'b'), (3, 'c')]

If you use .append(), you'll want to pass it a tuple of new values.

def combo(iter1, iter2): output = []
for index, value in enumerate(iter1): output.append((value,iter2[index])) return output

Error: Bummer! Didn't get the right output. For example, expected (10, 'T') as the first item, got (10, 'T') instead.

Hi, I copied your code into the challenge and applied the correct indentation and it worked:

def combo(iter1, iter2): 
    output = []
    for index, value in enumerate(iter1): 
        output.append((value,iter2[index])) 
    return output

Thanks Again, Haider. I just missed that. Thanks for catching

No problem :)

Anyone knows what we can do if the number of iterables is unknown?
