How to check if a list is empty with Python?

To check if a list is empty with Python, we can use the not operator.

For instance, we write:

a = []
if not a:
    print("List is empty")

We put not before a to check if a is empty.

Since this is True, we see 'List is empty' printed.

This works because empty lists are falsy.

Conclusion
