How to Create a Simple Function in Python Let's now try to understand the above statements using simple examples. This means that you could have a function that takes in no arguments, and returns nothing. Note that the arguments and the return statement are optional. The return statement returns control to the point where the function was originally called.

There's a return statement that returns the result of the operation on the arguments.

This is the body of the function that describes what your function does. This is because the arguments in the function call are the values used for the function's parameters.

When you call the function with specific values for these parameters, they're called arguments or actual parameters.

Please note that in function definition, the arguments that your function consumes are referred to as parameters.

If your function takes arguments, the names of the arguments (parameters) are mentioned inside the opening and closing parentheses.

You need to use the def keyword, give your function a name, followed by a pair of parentheses, and end the line with a colon (:).The following snippet shows the general syntax to define a function in Python: def function_name(parameters): Let's get started! Python Function Syntax In this post, we shall see how we can define and use our own functions. There's a whole wealth of built-in functions in Python. It lets you use functions by calling the function with required arguments, without having to worry about how they actually work. In programming, this is called abstraction. So long as you know how to use these functions, you don't have to worry about how they've been implemented. When you started coding in Python, you'd have used the built-in print() function in your Hello World! program 😀 and the input() function to read in input from the user. In this tutorial, we shall learn about user-defined functions in Python. In simple terms, when you want to do something repeatedly, you can define that something as a function and call that function whenever you need to.

In any programming language, functions facilitate code reusability.
