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.
