Functions

Functions\n\nFunctions are reusable blocks of code that you can call with arguments. Define a function using the def keyword followed by a name and optional parameters.\n\npython\ndef greet(name):\n return f'Hello, {name}!'\n\nprint(greet('Bob'))\n\n\nA return statement sends a value back to the caller. If a function reaches the end without return, it implicitly returns None.\n
