Python classes

Python is an Object-Oriented Programming (OOP) language. The way Python creates objects are with the class keyword. A Python object is most commonly a collection of functions (methods), variables, and attributes (properties). Once a class is defined, you can create instances of such a class. The class serves as the blueprint of the subsequent instances.

The topic of object-oriented programming is outside the scope of this chapter, so here is a simple example of a router object definition:

    >>> class router(object):    ...   def __init__(self, name, interface_number,     vendor):    ...     self.name = name    ...     self.interface_number = interface_number    ...     self.vendor = vendor    ...    >>>

Once defined, you are able to create as many instances of ...
