Delve deep into the world of Python dictionaries and sets with this comprehensive course. Discover how crucial and omnipresent dictionaries are in Python—they form the backbone of classes, modules, namespaces, sets, and more.

Course Overview

Gain a thorough understanding of associative arrays and their implementation via hash maps. Learn how to employ hash functions to enhance your custom classes. Explore Python dictionaries and sets along with the myriad of operations you can perform on them.

What You'll Explore

  • The technical implementation of associative arrays using hash maps

  • Understanding and creating custom hash functions

  • Advanced operations with both Python dictionaries and sets

  • Specialized dictionary structures like OrderedDict and its relation to the built-in dict post Python 3.6

  • Exploring Python's multi-sets through the Counter class

  • Leveraging ChainMap and UserDict for creating custom dictionaries

  • Comprehensive guide on serializing and deserializing dictionaries with JSON

  • Utilizing schemas for custom JSON deserialization

  • An introduction to useful libraries such as JSONSchema, Marshmallow, PyYaml, and Serpy

This is an advanced Python course intended for those who have a strong foundational knowledge of Python.
