Check if a list is empty in Python

The Problem

How do I check if a list is empty in Python?

The Solution

The Python style guide, PEP-8, recommends checking whether a list (or other sequence) is False to determine that it is empty. For example:

empty_list = [] if not empty_list: print("The list is empty.")
