A function in programming is a structured, reusable unit of code that is used to carry out a particular activity. Functions are a way to divide a large program into smaller, more manageable pieces. 

The "def" keyword in Python is followed by the function name, a pair of parentheses that might include parameters, and a colon to construct a function. The block of code to be executed by the function follows, indented underneath the definition line. 

  • def: In Python, the def keyword defines a function. It is used to create a block of organized, reusable code that a specific name can call, take input in the form of one or more parameters, and return an output, called the return value. 

You can also use the return statement inside a function to return a value or an object from the function. A function that does not have a return statement will return None by default. Functions are a key feature of structured programming, making the code more organized, reusable, and easier to understand and maintain. 

You may have a look at the code given below for creating a function in Python.

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in PyCharm 2021.3.
  2. The solution is tested on Python 3.9.7.

Using this solution, we are able to create a function in python with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to create a function in python.
