The function f(x,y) passed its output to the print function using the returnkeyword. Return variables. Functions can return variables. Sometimes a function makes a calculation or has some output, this can be given to the program with a return varaible. A function allows you to organize code in modular blocks and it makes code reusable. The more your Python code grows the more difficult it can get to manage it if you don’t use functions. Below you can see the full syntax of a function: def function_name(parameters): """docstring""". function_body.

Python Decorators. As mentioned earlier, A Python decorator is a function that takes in a function and returns it by adding some functionality.
