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 function () and function void )?

In short, an empty parameter list in a function declaration indicates that the function takes an unspecified number of parameters, while an empty parameter list in a function definition indicates that the function takes no parameters.

What is a void type function?

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.

What is a void in Python?

In Python, it is possible to compose a function without a return statement. Functions like this are called void, and they return None, Python’s special object for “nothing”. Here’s an example of a void function: Calling the two functions, you first notice the slight difference in the output.

What is a non-void function in Python?

# Python function to find whether number is positive or negative or zero. As you know Function which returns the values are called Non-void functions in python also called fruitful functions in python and functions returns nothing are called void type functions in python or non-fruitful functions in Python.

What is a non void function in C++?

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.
