Python 1 Module 4 Lesson 4 Banner

Overview

The student will consider the following...

Sometimes when programming we need a way to represent compound conditions. For example, the program might execute a block of code if the person's age is greater than or equal to 18 and they were born in North Carolina. Now the logic of our programs is beginning to get a bit more complex - not complicated - so that we can write more powerful programs. It is also important to understand the precedence of these operators in case your compound conditions require you to use several of the logical operators.

In this lesson, students will look at logical operators. Logical operators give the ability to connect or modify Boolean expressions. Three logical operators are not, or and and. These logical operators can be used in combination. With these logical operators, logical statements can be constructed, such as “I go to sleep when I am tired OR it’s after 9pm”, “I wear flip flops when I am outside AND it is NOT raining”.
