Python match-case Statement

📚 Python • 🎓 Beginner Friendly • ⏱ 10–15 min read

Introduction

Starting with Python 3.10, the language introduced the match and case statements. They provide a cleaner way to compare a value against multiple possible options, similar to the switch statement found in other programming languages.

Basic Syntax

day = 3

match day:
    case 1:
        print("Monday")
    case 2:
        print("Tuesday")
    case 3:
        print("Wednesday")
    case _:
        print("Unknown day")

The underscore (_) acts as the default case if none of the other cases match.

Matching Multiple Values

letter = "A"

match letter:
    case "A" | "E" | "I" | "O" | "U":
        print("Vowel")
    case _:
        print("Consonant")

Using Guards

A guard adds an additional condition using if.

number = 15

match number:
    case x if x > 10:
        print("Greater than 10")
    case _:
        print("10 or less")

match-case vs if...elif...else

if...elif...else	match...case
Works with any condition	Best for matching specific values
Very flexible	Cleaner when many choices exist
Ideal for complex logic	Ideal for menus and commands

Practical Example

command = input("Command: ")

match command.lower():
    case "start":
        print("Starting...")
    case "stop":
        print("Stopping...")
    case "restart":
        print("Restarting...")
    case _:
        print("Unknown command")

When Should You Use match-case?

Menu systems
Command interpreters
State machines
Game programming
Parsing user commands

Summary

The match and case statements make code easier to read when comparing one value against many possible options. For more complex conditions, if and elif are still the better choice.

Examples

The following examples help reinforce the concepts explained in this lesson.

<!DOCTYPE html>
<html>

<head>

<title>My First Page</title>

</head>

<body>

<h1>Hello World</h1>

</body>

</html>

💡 Pro Tip

Practice every concept immediately after reading it. Learning by doing is the fastest way to master HTML.

⚠ Common Mistake

Do not simply copy code examples. Type them yourself and experiment with small changes.

Best Practices

Write clean and readable HTML.
Indent your code consistently.
Use semantic HTML elements.
Validate your HTML regularly.
Test your pages in multiple browsers.
