Python Tutorial for Beginners 6: Conditionals and Booleans - If, Else, and Elif Statements
description
In this Python Beginner Tutorial, we will begin learning about if, elif, and else conditionals in Python. We will also be learning about Booleans and what evaluates to True and False. Let's get started.
