(Some python basics here)

Python Object Model

• Every value is an object and has
  • an identity ( like an address )
  • a type
  • a value
  • identity and type are strictly immutable
• Object can also have
  • attributes
  • methods

a is b # pointer comparison, are those 2 objects the same object?
a == b # content comparison

Modularization

Namespace = dictionary

keys are python identifiers, values can be functions, functions etc

A class is an object. It has a member that contains its names as a dictionary

names starting '__' are special

Modules

Source files that contains classes that can be imported

import foo

This would:

1. Create a new namespace N
2. Read and execute foo.py's code in N
3. foo = N
