Python | Check if two lists have any element in common
Sometimes we encounter the problem of checking if one list contains any element of another list. This kind of problems is quite popular in competitive programming. Let’s discuss various ways to achieve this particular task.
Method #1: Using any()
# Python code to check if two lists # have any element in common # Initialization of list list1 = [1, 2, 3, 4, 55] list2 = [2, 3, 90, 22] # using any function out = any(check in list1 for check in list2) # Checking condition if out: print("True") else : print("False") |

Method #2: Using in operator.
# Python code to check if two lists # have any element in common # Initialization of list list1 = [1, 3, 4, 55] list2 = [90, 22] flag = 0 # Using in to check element of # second list into first list for elem in list2: if elem in list1: flag = 1 # checking condition if flag == 1: print("True") else : print("False") |
