Using the Python not Operator (Overview)

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 course, 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
