How to Check if List is Empty in Python

If you want to check if a list is empty in Python, you just need to check for certain conditions.

We can easily check if a list is empty in Python. An empty list has length 0, and is equal to False, so to check if a list is empty, we can just check one of these conditions.

Below are three ways you can check if a list is an empty list in Python.

empty_list = []

#length check
if len(empty_list) == 0:
    print("List is empty!")

#if statement check
if empty_list:
    print("List is empty!")
