Function Keyword ArgumentsĪs we discussed, the order in which you pass arguments is the order in which your program will process them. So, in our last example, “number1” and “number2” are parameters, and 5 and 10 are arguments. An argument is the value that is passed to a function when it is called. » MORE: Python Input: A Step-By-Step GuideĪ parameter is the variable inside the parenthesis in a function. Then, our program prints “15 x 2 = 30” to the console. Next, we specify the arguments 15 and 2, which our program multiplies. Then, our program prints “5 x 10 = 50” to the console. Our program multiplies these values together to calculate 50. Toward the end of our program, we call our multiply_numbers function twice.įirst, we specify the arguments 5 and 10.
We must specify a number of arguments equal to those in the parameter list otherwise the Python interpreter will return an error. This is because we have set no default value for each argument.

Then, we print a statement to the console with the full mathematical sum written out, followed by the answer to the math problem. Next, we declare a Python variable called “answer” which multiplies the values of number1 and number2. We define these between brackets which is where the parameter list is defined.

The parameter names in the function that our code accepts are: number1 and number2. This is important because the more organized your code is, the easier it will be to maintain.įirst, we define a function called multiply_numbers. These blocks of code allow you to organize your code more efficiently. User-defined functions are reusable blocks of code written by you, the developer. Python str(), which converts a value to a string.Python len(), which calculates the length of a list.print(), which prints a statement to the console.In Python, there are two types of functions: user-defined and built-in. But, when you need to use a function, you can call it, and the code within the function will be executed. A function can be called anywhere after the function has been declared.īy itself, a function does nothing. Python functions return a value using a return statement, if one is specified. What is a Python Function?Ī function is a block of code that only runs when it is called. By the end of reading this tutorial, you’ll be an expert at writing functions in Python.

This tutorial will discuss, with examples, the basics of Python functions, how to create and call a function, and how to work with arguments. A function can be executed as many times as a developer wants throughout their code.įunctions allow developers to reduce repetition in their code because they can execute the same block of code multiple times over in one program. They allow developers to write blocks of code that perform specific tasks. Functions can return a value using a return statement.įunctions are a common feature among all programming languages. A function can be called from anywhere after the function is defined. To run the code in a function, you must call the function.
