Join 2 elements of a list

Question

If I have 2 lists:

list1 = ['1', '2', '3', '4']
list2 = ['a', 'b', 'c', 'd']

How can I get a 3rd list with the output

list3 = ['1a', '2b', '3c', '4d']

I have tried Zip and Join

but Zip still leaves the items separated and Join removes all the separators entirely

Thanks guys!

To combine two items of two lists as string you need to iterate through both lists at the same time and concatenate the two items as strings.

list1 = [1, 2, 3, 4]
list2 = ['a', 'b', 'c', 'd']
list3 = [str(x) + str(y) for x, y in zip(list1, list2)]
print(list3)

the output will be:

['1a', '2b', '3c', '4d']
