Match Case

Instead of writing many if..else statements, you can use the match statement.

The match statement selects one of many code blocks to be executed.

Why Use match-case?

match-case makes code:

• Cleaner
• Easier to read
• Better for handling multiple possibilities
• Suitable for pattern-based decisions

It is especially helpful when:

• Comparing against many possible values
• Working with structured data (like tuples or dictionaries)
• Replacing long chains of if-elif-else statements

match expression:
  case x:
    code block
  case y:
    code block
  case z:
    code block

This is how it works:

• The match expression is evaluated once.
• The value of the expression is compared with the values of each case.
• If there is a match, the associated block of code is executed.

The example below uses the weekday number to print the weekday name:

day = 4
match day:
  case 1:
    print("Monday")
  case 2:
    print("Tuesday")
  case 3:
    print("Wednesday")
  case 4:
    print("Thursday")
  case 5:
    print("Friday")
  case 6:
    print("Saturday")
  case 7:
    print("Sunday")

Output:
