Here in this program, we defined three functions and in each function, we added the tags for bold, italic and underline respectively. A decorator is a design pattern in Python that enables you to change a function’s behaviour by enclosing it in another function. A modified version of the original function is returned by the outer function, which is referred to as the decorator. Applying several decorators inside of a function is known as chaining decorators. Python enables us to add several decorators to a function. Combining numerous effects, it makes decorators helpful for reusable building blocks.
