Properties of functions:- - We can also write a code for the function inside another function. - We can assign a function to another function in python as a function is also an object. - A function is an instance of the Object type. - We can store the function in a variable. - We can also pass the function as a parameter to another function. - A function from a function can also be returned. #2 - Decorators are used to add extra features to the existing functions. - Decorators can change the behaviour of an existing function at the compile itself. #3 Properties of Decorators:- -The outer function is called the decorator, which takes the original function as an argument and returns a modified version of it. - Decorator contains an outer function that also takes a function as an argument. - Inside the outer function, there is another function that takes a number of parameters as per the logic as an argument. - Inner function contains the code for the logic that must be contained in the previously defined normal function. - Inner function returns the values as per the required code that can be equal to the number of arguments passes in an inner function. - Outer function return an inner function. - In the main code, we have to call the outer function of a decorator and pass the normal function as an argument.
