The outer function is called the decorator, which takes the original function as an argument and returns a modified version of it. Before we learn about decorators, we need to understand a few important concepts related to Python functions. Also, remember that everything in Python is an object, even functions are objects. We can include one function inside another, known as a nested function. For example, Here, we have created the inner() function inside the outer() function. We can pass a function as an argument to another function in Python. For Example, Output In the above example, the calculate() function takes a function as its argument. While calling calculate(), we are passing the add() function as the argument. In the calculate() function, arguments: func, x, y become add, 4, and 6 respectively. And hence, func(x, y) becomes add(4, 6) which re
