Mythology

The first great achievement of Apollo was to slay the huge serpent Python. In some texts Python is an enormous dragon and not a serpent.
But who was this mythical creature? Python was created out of the slime and mud left after the great flood. She was appointed by Gaia (Mother Earth) to guard the oracle of Delphi, known as Pytho. After having defeated Python Apollo remade her former home and the oracle as his own.

Quote of the Day:

"Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space." (Douglas Adams, The Hitchhiker's Guide to the Galaxy)

If you have the choice working with Python 2 or Python 3, we recomend to switch to Python 3! You can read our Python Tutorial to see what the differences are.

Use Cases for Metaclasses

Introduction

Unfortunately, this chapter is not available for Python2.x. But there is Python 3 version available.

We recommend to continue with our chapter "Python3: Count Function Calls" of our Python3 tutorial. "Counting Function Calls" is a great use case for metaclasses.
