Confused on why this logic is not working.

I've looked up this question and honestly, I don't understand the working explanation or why mine simply doesn't work.

combo.py
# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]

def combo(data1, data2):
    a_list = []
    for i in enumerate(data1):
        a_list += (data1[i], data2[i])

    return a_list

The "enumerate" function returns a sequence of tuples, which would not be suitable to use as indexes. You might consider using a "range" instead.

Also, when using the "+=" operator, the expression on the right should be a list. Or you could add a tuple directly using the "append" function.
