Method is a function that is associated with an object. In Python, method is not unique to class instances. Any object type can have methods.
It is said that everything in Python is an object. In python, functions too are objects. So they have attributes like other objects. We can also assign new attributes to them, as well as retrieve the values of those attributes. Functions can have even functions written inside them.
