A match statement takes an expression and compares its value to successive patterns given as one or more case blocks. Specifically, pattern matching operates by: 1. using data with type and shape (the subject) 2. evaluating the subject in the match statement 3. comparing the subject with each pattern in a case statement from top to bottom until a match is confirmed. 4. executing the action associated with the pattern of the confirmed match If an exact match is not confirmed, the last case, a wildcard _, if provided, will be used as the matching case. If an exact match is not confirmed and a wildcard case does not exist, the entire match block is a no-op. # Match-case statement (switch): An alternative to using many 'elif' statements # Execute some code if a value matches a 'case' # Benefits: cleaner and syntax is more readable def is_weekend(day): match day: case "Saturday" | "Sunday": return True case "Monday" | "Tuesday" | "Wednesday" | "Thursday" | "Friday": return False case _: return False print(is_weekend("Monday"))
