How to remove an element from a list if it is not in another list?

Question

Python

Can you tell me how to remove the elements of a list if it is not in another list?
Let's say we have two lists:

list1 = [1, 2, 3, 4, 5, 6]
list2 = [2, 3, 5]

From list1, you need to remove all elements that are not in list2 and get the following list:
list1 = [2, 3, 5]

Answer 1

list1 = [ n for n in list1 if n in list2 ]
