Title of the talk

The Python Type System

Description

Python's type system is as absurd as it is fascinating. "Everything is an object" is an understatement. In this talk, In this talk, we will take a look at how Python's type system is implemented -- specifically its objects and classes. We'll take a look at how classes are also objects, the consequences of that, and how it is implemented in the interpreter. Next, we'll try to figure out where the self in method comes from. We'll top it off with how we can create a function decorator that will take away the need for a class keyword.

Outcomes:

• Familiarity with classes as objects
• Getting known to confusing behaviour
• Exploring PyObject from the CPython interpretr
