If it’s true, then the whole expression is true. In this case, the final result depends on the right operand’s truth value. In contrast, the and operator evaluates the operand on the right only if the first operand is true. Python prevents this by short-circuiting the evaluation. It would be a waste of CPU time to evaluate the remaining operand. Having a false left operand automatically makes the whole expression false. In this situation, there’s no need to evaluate the operand on the right. If it’s false, then the whole expression is false. To determine the final result of an and expression, Python starts by evaluating the left operand. In other words, Python evaluates the operand on the right only when it needs to. Python’s logical operators, such as and and or, use something called short-circuit evaluation, or lazy evaluation. Remove ads Short-Circuiting the Evaluation Even if you don’t use all the features of and, learning about them will allow you to write better and more accurate code. You’ll also code a few practical examples that will help you understand how to use the and operator to approach different problems in a Pythonic way.

Use the and operator in non-Boolean contexts to make your code more concise.Use the and operator in Boolean contexts to decide the course of action of your programs.Build and understand Boolean and non-Boolean expressions that use the and operator.Understand the logic behind Python’s and operator.In this tutorial, you’ll learn about the and operator and how to use it in your code. You can use them to check if certain conditions are met before deciding the execution path your programs will follow. Python has three Boolean operators, or logical operators: and, or, and not.
