In this article, we will study how python functions work right from defining them to calling them. We will study in detail the types of functions in python and how to call a function in python. Applications and Uses of functions are a part of this article on python functions.<\/p>\n

What is a Python Function?<\/h2>\n

Functions in Python are defined to increase the reusability of code and divide the code into modular tasks instead of rewriting the same part of code over and over again. Functions are based on DRY (Don\u2019t Repeat Yourself) where we try to minimize the redundancy in our code and reuse the already defined components of our code.<\/p>\n

There are various types of functions in Python. Generally, a function that a user defines has a def \u2018keyword\u2019 which is used to indicate that a function is created with a suitable or user-provided function name and inside the function is a set of instructions or statements in an indented manner. If there is a need, value can be returned from the called function.<\/p>\n

Argument in Python Function<\/h2>\n

Python functions have the ability to pass arguments in the function call which makes it easy to preserve values from being reinitialized and use them repetitively. As we are aware of how to call a function, let us look at a code where we will pass a value on calling a value and print that value as a statement embedded within the function.<\/p>\n
