Using the “not” Boolean Operator in Python
Python’s not
operator allows you to invert the truth value of Boolean expressions and objects. You can use this operator in Boolean contexts, such as if
statements and while
loops. It also works in non-Boolean contexts, which allows you to invert the truth value of your variables.
Using the not
operator effectively will help you write accurate negative Boolean expressions to control the flow of execution in your programs.
In this tutorial, you’ll learn:
- How Python’s
not
operator works - How to use the
not
operator in Boolean and non-Boolean contexts - How to use the
operator.not_()
function to perform logical negation - How and when to avoid unnecessary negative logic in your code
You’ll also code a few practical examples that
