This example will demonstrate how an if else statement works within Python. #If none of the previous conditions were met, run this code Example of Using an if else Statement #Code here will be executed if the condition is met However, if the condition evaluates to true, the if statement code block will run and our else block will be skipped. So, if our if statement condition evaluates to false, the else code block will execute. You can add an else statement after an if statement if you want a specific code block to run if the condition of our if statement is not met. Since x equals 15, the code block containing our print function will run, resulting in the output below. If the condition evaluates to true, the block of code will run. Our if statement condition is that x must equal 15. In our example below, we have a simple Python script that uses an if statement to check the value of x. #Code here will be executed if the condition is met Example of Using the if Statement If you do not use the correct indentation, an error will occur.īelow is an example of how you can structure an if statement in Python. You can use a single space or four spaces as long as the spacing is consistent for the indentation. Otherwise, it will skip past it.Īs we mentioned earlier, the code block for an if statement will need to be indented. If the condition is true, the indented code will run. By using the if statement, you will be able to check to see if a condition evaluates to true or false. The most basic Python conditional statement is the if statement. Example of Using the if elif else Statement.However, in Python 3.10.0 and later, there is support for match and case statements, which are very similar to a switch. ![]() Python does not have built-in support for switch statements, so you need to use if elif logic. However, I strongly recommend that you learn the basics first. If you want a shorthand way to write a conditional statement, I recommend learning more about ternary operators or conditional expressions. Therefore, I highly recommend taking the time to learn about the different operators you can use. To build a good expression for a conditional statement, you will need to understand how to use Python operators. We will also touch on nesting if statements. We will go through how to correctly write if, if else, if elif and, if elif else statements. ![]() This tutorial will go through the many ways you can structure conditional statements. Depending on the result, you can skip or execute specific code blocks. The statement conditions will need to evaluate to be true or false. In this tutorial, we will be showing you how to use if, else, and elif conditional statements in Python.Ĭonditional statements are a programming fundamental that you will need to know if you wish to program software using Python or any other programming language.īy using conditional statements, you can control the execution of code.
