How Can I Check if a Python List is Empty?

Checking for an Empty List

In Python, determining if a list is empty is a common task. Let's explore a method for performing this check.

Method:

The implicit booleanness of an empty list can be utilized to determine if it is empty. When a list is empty, its evaluation as a boolean expression evaluates to False.

Example:

Consider the following list:

a = []

To check if 'a' is empty, we can use the following code:

if not a:
    print("List is empty")

Explanation:

The not operator inverts the boolean value of 'a'. Since an empty list evaluates to False, the expression not a evaluates to True, causing the 'if' statement to execute.

This Pythonic and concise approach leverages the inherent boolean nature of empty lists.
