Python If Else Tutorial

Python’s conditional statements allow you to execute different blocks of code based on certain conditions. The most common conditional statements in Python are if, elif (else if), and else. Here’s a detailed look at how to use these statements with various examples.

Basic if Statement

The if statement is used to execute a block of code only if a specified condition is true.


The else Statement

The else statement can follow an if statement and is executed if the if condition is false.


The elif Statement

The elif (else if) statement allows you to check multiple conditions after the initial if condition. If the if condition is false, it checks the elif conditions in order.


Nested if Statements

You can nest if statements within other if statements to check for further conditions.


Short Hand if

If you have only one statement to execute, you can put it on the same line as the if statement.


Short Hand if-else

This form, known as a ternary operator, allows you to execute a single statement for each of the true and false conditions of the if.


Combining Logical Operators

Use logical operators (and, or, not) to combine conditional statements.


The pass Statement

if statements cannot be empty, but if you for some reason have an if statement with no content, use the pass statement to avoid an error.


Understanding and effectively using conditional statements are crucial in Python programming. They allow you to control the flow of your program and make decisions, thereby making your programs more dynamic and responsive to different inputs or situations.
