Adding parentheses in a loop when appending to a list in python

Question

I have two lists:

one = ['a','b','c','d']
two = ['d', 'c',' b', 'a']

I would like to create a loop that produces the following output: [('a', d'), ('b', 'c'), ('c','b'), ('d', 'a')]

This is my current code but it is not properly adding the parentheses.

final_list = []
for i in range(len(a)):
    final_list.append(a[i])
    final_list.append(b[i])

Answer 1

Append tuples in the for loop:

for i in range(len(a)):
    final_list.append((a[i],b[i]))

Answer 2

You are looking for a list of tuples, zip will do it for you

final_list = [t for t in zip(one, two)]
# [('a', 'd'), ('b', 'c'), ('c', 'b'), ('d', 'a')]

Or as suggested you can also do it without the explicit loop

final_list = list(zip(one, two))
