Functions can be called only by its name, as it is defined independently. But methods can't be called by its name only, we need to invoke the class by a reference of that class in which it is defined, i.e. method is defined within a class and hence they are dependent on that class.

Comparison Between Method and Function in Python Python method is called on an object, unlike a function. ... Since we call a method on an object, it can access the data within it. A method may alter an object's state, but Python function usually only operates on it, and then prints something or returns a value.

A function is meant to do some processing on the input and return a single value, whereas a task is more general and can calculate multiple result values and return them using output and inout type arguments. Tasks can contain simulation time consuming elements such as @, posedge and others.

Void simply means nothing. It doesn't take any parameters nor it returns anything. Return is use to give command back to the calling function and it returns value to Calling function.

There is one more major difference between the two methods is when the object we are converting is an array. When you convert an array using Object. ... Second difference is when the object is null, ValueOf() returns a String "null", while toString() will return null pointer exception.

function A function can be invoked with a list of arguments to produce a result. A function has a parameter list, a body, and a result type. Functions that are members of a class, trait, or singleton object are called methods. Functions defined inside other functions are called local functions.
