Return vs Print: Key Diff Functions Without Return Functions without return values are used for their "side effects" such as printing messages, writing to files, or modifying data. They perform actions rather than computing results. Both patterns are valid; the choice depends on the function's purpose. Return Exits Immediately Each condition checks the age and returns immediately if it matches. The function never runs more code than necessary. When a return is executed, Python skips all remaining code in the function.
