What is the difference between void and non-void function in Python?

What is the difference between void and non-void function in Python?

Since nothing was returned to the variable, Python printed ”None” to the console. Such functions which do not have a return statement in them are called void functions. Void functions are those that do not return anything. ”None” is a special type in Python, which is returned after a void function ends.

What is the non-void function?

If the function is non-void,it means it has to return something before reaching the end of function block[ _} ]. So, when we give only if and else-if statements the compiler cannot tell from that code,that any of these statements will be evaluated to true and return something.

The void type, in several programming languages derived from C and Algol68, is the type for the result of a function that returns normally, but does not provide a result value to its caller. Usually such functions are called for their side effects, such as performing some task or writing to their output parameters.

Void and Non-Void – represents the return type of a function. Void Function: This function will not return any value and can be used for display purpose. Non-Void Function: These type of functions can be used to perform any operations and can return the output through the name of the function.

What is the difference between a void function and a value-returning function?

Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword “void.” A void function performs a task, and then control returns back to the caller–but, it does not return a value.
