Branching with if-else

Basic if-else Structure Since balance is 150, the condition is True, so the if block runs and the else block is skipped. Exactly one of the two blocks will always execute. The else Block Executes When the condition is False, the else block runs instead: Now balance is 50, so the condition is False. Python skips the if block entirely and executes the else block. The final print still runs because it is outside both blocks. Mutually Exclusive Paths With if-else, exactly one of the two code blocks will always run. They are mutually exclusive: if one runs, the other does not. This is useful when you have exactly two possibilities: Data Validation Example In data engineering, if-else is commonly used for validation and categorization: The single equals sign is reserved for assignment.
