The code above is equivalent to add_numbers(5, 4)Ī Python function may or may not return a value. In Python, we call it Keyword Argument (or named argument). We can also call the function by mentioning the argument name as: add_numbers(num1 = 5, num2 = 4) In the above example, we have created a function named add_numbers() with arguments: num1 and num2. Here, add_numbers(5, 4) specifies that arguments num1 and num2 will get values 5 and 4 respectively.Įxample 1: Python Function Arguments # function with two arguments For example, # function call with two values If we create a function with arguments, we need to pass the corresponding values while calling them. For example, # function with two arguments An argument is a value that is accepted by a function.

The control of the program jumps to the next statement after the function call.Īs mentioned earlier, a function can also have arguments.

All codes inside the function are executed.

When the function is called, the control of the program goes to the function definition.

Here's how the program works: Working of Python Function In the above example, we have created a function named greet(). Here's how we can call the greet() function in Python. Now, to use this function, we need to call it. In the above example, we have declared a function named greet().

We will learn about arguments and return statements later in this tutorial. This function doesn't have any arguments and doesn't return any values. Here, we have created a function named greet(). return (optional) - returns value from a function.arguments - any value passed to function.function_name - any name given to the function.def - keyword used to declare a function.The syntax to declare a function is: def function_name(arguments): User-defined functions - We can create our own functions based on our requirements.

Standard library functions - These are built-in functions in Python that are available to use.There are two types of function in Python programming: You can create two functions to solve this problem:ĭividing a complex problem into smaller chunks makes our program easy to understand and reuse. Suppose, you need to create a program to create a circle and color it. A function is a block of code that performs a specific task.
