In this tutorial, we will learn about python if.else statements with the help of examples. As well as the while statement just introduced, python uses a few more that we will encounter in this chapter These conditions can be used in several ways, most commonly in if statements and loops An if statement is written by using the if keyword In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a. In this example, the code assigns the value 3 to variable x and uses an if.else statement to check if x is equal to 4
If true, it prints yes Otherwise, it prints no, demonstrating a conditional branching structure. This beginner's tutorial will explain what conditional statements are, why they're important, the different types of statements, and how to work with them. First, you’ll get a quick overview of the if statement in its simplest form Next, using the if statement as a model, you’ll see why control structures require some mechanism for grouping statements together into compound statements or blocks You’ll learn how this is done in python.
Else.), including how to specify multiple conditions and negated conditions. Python uses the if keyword to implement decision control Python's syntax for executing a block conditionally is as below Any boolean expression evaluating to true or false appears after the if keyword Symbol and press enter after the expression to start a block with an increased indent. You use the if statement to execute a block of code based on a specified condition
The syntax of the if statement is as follows Python (python) the if statement checks the condition first Otherwise, it ignores the statements.
