python void functions

in python, functions play a crucial role in organizing and structuring code. void functions, also known as functions with no return value, are functions that perform a task without returning any value. this tutorial aims to provide a comprehensive understanding of python void functions, their syntax, and how to use them effectively.
let's start by creating a simple void function. the syntax for defining a function in python is as follows:
here's an example of a void function:
in this example, the greet function takes a parameter name and prints a greeting message to the console. notice that there is no return statement in the function.
void functions can take parameters, which are placeholders for the values the function will work with. when calling the function, you provide arguments, which are the actual values that will be used by the function.
in this example, add_numbers takes two parameters (a and b) and prints the sum of the arguments passed when calling the function.
void functions implicitly return the none value if there is no explicit return statement. none is a special constant in python that represents the absence of a value.
here, the do_nothing function explicitly returns none, and when the function is called, the result is assigned to the variable result, which is then printed.
void functions are essential in python for performing tasks without the need to return a value. they help in organizing code, improving readability, and promoting reusability. u
