Learn: Comparison Operators

Welcome!Welcome back! In this lesson, we will build on your knowledge of variables, selection, and iteration to explore comparison operators. These operators help us compare values and make decisions in our programs.By the end of this lesson, you'll understand how to use operators like ==, !=, , , >, and >= to control the flow of your code.

What Are Comparison Operators?Comparison operators are used to compare two values. They return a Boolean result: either true or false. This is essential for decision-making in programming.For example, you can check if two numbers are equal, if one is greater than the other, or if they are not equal.

Key Comparison OperatorsHere are the comparison operators we’ll focus on:==: Checks if two values are equal.!=: Checks if two values are not equal.: Checks if the first value is less than the second.: Checks if the first value is less than or equal to the second.>: Checks if the first value is greater than the second.>=: Checks if the first value is greater than or equal to the second.

How Do Comparison Operators Work?Comparison operators compare two values and return true or false. For example:5 == 5 returns true because the numbers are equal.10 != 5 returns true because the numbers are not equal.7 returns false because 7 is not less than 3.

Using Comparison Operators in ProgramsComparison operators are often used in conditional statements like if and while to control program flow. For example:if age >= 18: print('You are an adult')The program checks if age is greater than or equal to 18. If true, it prints a message.

Review Time!Well done! You've learned about the different comparison operators and how they work. Let's test your understanding with a few more questions.
