Arguments and Return Values

Arguments and Return Values\n\nFunctions can accept positional, keyword, default, and variable‑length arguments.\n\npython\ndef repeat(message, times=2):\n return message * times\n\nprint(repeat('Hi')) # HiHi\nprint(repeat('Hi', 3)) # HiHiHi\n\n\n- Positional arguments are matched by order.\n- Keyword arguments let you specify the parameter name (repeat(message='Hi', times=3)).\n- Default values (times=2) make an argument optional.\n- Use *args to collect extra positional arguments and **kwargs for extra keyword arguments.\n
