Zen of Python Classes - Introduction
The neat thing about Python is that it already has enormous utility as a scripting language without people having to worry about writing a single class of their own. This tutorial assumes some knowledge of basic Python, but only an introductory idea of what classes and OOP are. If you are such a beginner, you should find this tutorial to be a very clear and easy intro on how object orientation (OO) in Python works.
The Simplest Python Class
>>> class C: pass
Yes, that's it! And precisely why so many people love this "wrist-friendly" language. In keeping with Zen mind, don't worry about constructors, destructors and all that claptrap for now. Let's just prove to ourselves that we have a class on hand.
One important thing to realize is that the uninstantiated class itself is an object.
It is an object and therefore it has a type. It's type is
>>> type(C) <type 'classobj'>
Let's instantiate an instance of C and examine it:
>>> i=C() >>> type(i) <type 'instance'> >>> i <__main__.C instance at 0x0353B990>
i is indeed an instance of
C, the latter
being found in the
