Method decorators in Python

This post assumes you have a basic understanding of Decorators. If not, you can read our introductory post on Decorator

Method decorators

In introductory post, we learnt about function decorators. In this post we'll see method decorators:

Let's write a Class and a method on it which we will decorate later.

>>> class Person(object):
...     def __init__(self, name):
... = name
...     def print_name(self):
...         print

Create a Person instance. p1 refers to the created instance.

>>> p1 = Person("eddard")

Call print_name on Person.

>>> p1.print_name()
eddard     #output

Something worth noting about previous Python statement. Quoting from docs ...

Understanding decorators in Python

We will divide this post into two topics

  1. Functions are objects and they can be passed around.
  2. Writing few decorators

As usual, I will be trying out the code in ipython and I suggest you to do the same.

Functions can be passed around similar to any other object in Python.

If you are already familiar with this, you can skip to next section.

Let's first write a class.

>>> class A(object):
...     def __init__(self, a):
...         self.a = a

Let's create an instance of this class.

>>> obj = A(5)    
>>> print obj.a
5                 #output ...
