If/Else & Match

if, elif, and else choose code paths based on conditions. Always indent the block after the colon.

Python If...Else

if, elif, and else choose code paths based on conditions. Always indent the block after the colon.

Combine conditions with and, or, and not.

Real-life example: If/else is a gatekeeper — if you have a ticket, you enter; else you wait outside.

Grade checker

marks = 86
if marks >= 90:
    grade = "A"
elif marks >= 75:
    grade = "B"
else:
    grade = "C"
print(grade)

Python Match

match/case (Python 3.10+) compares a value against patterns — cleaner than long elif chains.

Use _ as the default case wildcard.

Real-life example: match is a vending machine menu — press A for chips, B for soda, default for cancel.

match/case

status = "success"
match status:
    case "success":
        print("Done!")
    case "error":
        print("Failed.")
    case _:
        print("Unknown.")
