Master Python Conditional Statements in 3 Minutes: A Quick Guide

Python Conditional Statements

Python conditional statements execute code blocks based on the truth value (True or False) of one or more expressions.

You can understand the execution flow with the diagram below:

In Python, any non‑zero and non‑null value is considered true; 0 or null is false.

The basic if statement has the form:

If the condition evaluates to true, the indented block following the if is executed.

The optional else clause runs when the condition is false, as shown in the example below:

The output of this example is:

Comparison operators such as >, <, ==, >=, and <= can be used in conditions.

When multiple conditions are needed, you can combine them with or (any true) or and (all true). The elif keyword allows additional branches.

The output of the multiple‑condition example is:

Parentheses can be used to control evaluation order; logical operators have lower precedence than comparison operators.

You can also place an if statement on a single line, as demonstrated below:

The output of the single‑line example is:
