How to implement the Python Match.

Question

ICSM · Answer

Python introduced the match statement (structural pattern matching) in
Python 3.10. It’s somewhat like switch in 
other languages, but far more powerful because it can destructure and match data structures.
Basic Syntax
def http_status(code):
    match code:
        case 200:
            return "OK"
        case 404:
            return "Not Found"
        case 500:
            return "Internal Server Error"
        case _:
            return "Unknown"
match andlt;expressionandgt; → evaluates the value.case andlt;patternandgt; → checked against the value._ → wildcard (default / “else”).
Matching Multiple Values
match command:
    case "start" | "run":
        print("Starting...")
    case "stop" | "end":
        print("Stopping...")
Here | acts like OR.
Matching with Variables (Destructuring)
You can “unpack” objects inside patterns:
point = (3, 4)
match point:
    case (0, 0):
        print("Origin")
    case (x, 0):
        print(f"On X-axis at {x}")
    case (0, y):
        print(f"On Y-axis at {y}")
    case (x, y):
        print(f"Point at ({x}, {y})")
Using
if (Guards)
number = 15
match number:
    case x if x andgt; 10:
        print("Greater than 10")
    case x:
        print("10 or less")
Matching Classes / Data Classes
class Point:
    def __init__(self, x, y): 
        self.x = x
        self.y = y
p = Point(1, 2)
match p:
    case Point(x=0, y=0):
        print("Origin")
    case Point(x, y):
        print(f"Point({x}, {y})")
Key Points
match is not just switch — it supports destructuring.Patterns can be literals, variables, wildcards, sequences, dicts, classes, etc.Guards (if) add conditions inside case._ matches anything (like default in switch).
