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.

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.
