Exercise List Overlap

[Damian]

Hi all,

I've got an exercise and I'm trying to solve it.

I'm a Python beginner.

EXERCISE
Take two lists (you can use the ones in the example below) and write a program that prints a list that contains only the elements of the two lists that are equal and in the same position without duplication.
e.g.,
a = [5, 3, 5, 44, 4, 55, 4]
b = [5, 4, 55, 4, 4, 55, 4, 55, 9, 10, 11]


So, this is what I've done:

a = [5, 3, 5, 44, 4, 55, 4]
b = [5, 4, 55, 4, 4, 55, 4, 55, 9, 10, 11]

list_of_tuples = list(zip(a, b))
result = []
for tuple in list_of_tuples:
if tuple[0] == tuple[1]:
result.append(tuple[0])

print(result)
# [5, 4, 55, 4]

Then I've to keep the list order and skip duplicates.

What do you suggest me to do?
Do you think there's a better way of solving the problem from the beginning? (from the point of view of a beginner of course)
