Python: Check if Array/List Contains Element/Value

Introduction

In this tutorial, we’ll take a look at how to check if a list contains an element or value in Python. We’ll use a list of strings, containing a few animals:

animals = ['Dog', 'Cat', 'Bird', 'Fish']

Check if List Contains Element With for Loop

A simple and rudimentary method to check if a list contains an element is looping through it, and checking if the item we’re on matches the one we’re looking for. Let’s use a for loop for this:

for animal in animals:
    if animal == 'Bird':
        print('Chirp!')

This code will result in:

Chirp!

Check if List Contains Element With in Operator

Now, a more succint approach would be to use the built-in in operator, but with the if statement instead of the for statement. When paired with if, it returns True if an element exists
