Python Deep Dive for Programmers

Python refreshment

• Types
• Flow of control
• Functions
• Strings
• Collections  

Functional programming in Python.

• Inner functions and closure.
• Functions as objects.
• Higher-order functions: decorator.
• Lambda functions: definition and typical uses.

Data abstraction and Advanced collection

• Magic methods: Indexed and keyed access.
• Magic methods: Sequential access – Iterator / generator protocol.
• List emulation
• Dictionar
• Bound and unbound methods.
• Using metadata.

Object-oriented programming in Python

• The need for substitutability. The Python approach: “duck typing”
• Commonality and variance. Inheritance. Abstract base class. Constructor override
• The message paradigm. Left-handed polymorphism. The principle of substitutability
• Double polymorphism: multi-methods, double dispatch
• Polymorphic Design Patterns in Python using metadata: Composite
• Design patterns made trivial in Python: Singleton, Dynamic Pluggable Factory, Factory Method, Prototype, Proxy

Error and Exception handling

• Writing to stderr
• Controlling warnings
• Exception handling
• Multiple exceptions
• The Python exception hierarchy
• The raise statement
• Raising our own Exceptions
• Assert

Packaging and Interop

• Modules
