Python BootCamp -> Match Case

A Clean Code Must Read

Hello Everyone,

Python 3.10 introduced a powerful and expressive feature: the match case statement. Inspired by pattern matching found in languages like Rust and Haskell, this feature allows for more readable and concise code when dealing with complex data structures. Whether you're processing nested dictionaries, handling various data types, or implementing control flow based on patterns, the match case statement can significantly simplify your code.

Word Adventure

Let’s go on an adventure where textual commands determine actions.

command = input().split()
if command == "quit":
    print("Exiting...")
elif command == "look":
    print("Looking...")
elif len(command) > 1:
    action, *args = command
    print(f"Action: {action}, Args: {args}")
else :
    print("Invalid command")

• The code above is less readable and contains a staircase of if elif else statements. Let's refine it using match case.

Less refine it.

command = input()

match command.split():
    case ["quit"]:
        print("Exiting...")
    case ["look"]:
        print("Looking...")
    case [action, *args]:
        print(f"Action: {action}, Args: {args}")
    case _:
        print("Invalid command")
