Python Pattern matching

1. What is Pattern Matching?

Pattern matching is a clean way to check many conditions in Python.

In simple words:
👉 Python looks at a value
👉 It tries to match patterns
👉 When a match is found, that block runs

Python uses match and case keywords.

This feature is available from Python 3.10+.

2. Why Use Pattern Matching?

Pattern matching:
✔ Makes code clean
✔ Replaces long if-elif chains
✔ Easy to read and understand

3. Simple match-case Example

Example

Output:

4. Using case _ (Default Case)

 

Example

5. Match with Strings

Example

6. Multiple Values in One Case

Example

7. Match with Numbers (Calculator Example)

Example

8. Match with Tuples

Example

9. Match with Lists

Example

10. Match with Conditions (Guards)

You can add conditions using if.

Example

11. Pattern Matching vs if-elif

if-elif (Long)

match-case (Clean)

12. Common Beginner Mistakes

❌ Using Python version < 3.10
❌ Forgetting case _
❌ Thinking match works like switch (it’s smarter)
❌ Using = instead of :

13. Simple Practice Examples

Example 1: Traffic Light

Example 2: Menu Selection

Example 3: Login Role

14. When Should You Use Pattern Matching?

✔ Many conditions
✔ Structured data (list, tuple)
✔ Clean readable code
✔ Modern Python programs

15. Summary (Python Pattern Matching)

✔ Uses match and case
✔ Cleaner than if-elif
✔ Supports numbers, strings, lists, tuples
✔ Supports conditions
✔ Powerful and modern feature
