Python List Similarity | List Comprehension

Introduction

In Python, it is often necessary to compare two lists and find the elements that exist in both lists. This can be achieved by using list comprehension, a powerful feature of Python that allows us to create new lists based on existing lists.

List Similarity

Write a function similarity(a, b) that takes two lists a and b as arguments and returns a new list that contains only the elements that exist in both a and b.

To solve this problem, we can use list comprehension to iterate over the elements of a and check if they exist in b. If an element exists in both lists, we add it to a new list.

def similarity(a, b):
  return [item for item in a if item in b]

similarity([1, 2, 3], [1, 2, 4]) ## [1, 2]
