Python Python Collections (2016, retired 2019) Tuples Combo

Why does my code throw an error?

def combo(iterable1, iterable2): list_of_tuples = [] for a in iterable1 and b in iterable2: list_of_tuples.append([a, b]) return list_of_tuples

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

I guess this syntax is incorrect - for a in iterable1 and b in iterable2:. I don't think I've seen multiple for..in chained together like that.

Also, your return list_of_tuples statement should be outside the for loop.

There's also the enumerate() function -

def combo(iterable1, iterable2):
    return [(i, iterable2[idx]) for idx, i in enumerate(iterable1)]
