Pattern Matching

Pattern matching is a powerful programming feature adopted by various programming languages that I would love to see in newer versions of Python. Here is an example from Rust which shows how to match against an integer value:

    fn print_number(n: int) {
      match n {
        x if x < 0    => println!("less than zero"),
        0             => println!("zero"),
        1 | 2         => println!("one or two"),
        y @ 3..10     => println!("3 <= {} <= 10", y),
        _             => println!("greater than 10")
      }
    }
