Python Check If a List Contains Elements of Another List

In this tutorial, we are going to see how to check if a Python list contains all the elements of another list and display the result using the print() function.

Suppose we have two lists, list1 and list2, like below.

list1 = ['Hi' ,  'welcome', 'to', 'stackhowto']
list2 = ['to', 'stackhowto']

 

 

Check If a List Contains Elements of Another List Using all() Method

check = all(item in list1 for item in list2)

if check:
    print ("List1 contains all the elements of list2")
else :
    print ("List1 does not contain all the elements of list2")

Output:

List1 contains all the elements of list2

The all() function returns True if all the elements of an Iteration are true, otherwise it returns False.
 

Check If a List Contains Elements of Another List Using any() Method

check =  any(item in list1 for item in list2)

if check:
    print ("List1 contains all the elements of list2")
else :
    print ("List1 does not contain all the elements of list2")

Output:

List1 contains all the elements of list2

Python’s any() function is one of the built-in functions. It takes the iterable as an argument and returns “True” if any of the elements is “True”. If the iterable is empty, it returns “False”.
