Classes are essentially dictionaries, modules are dictionaries, namespaces are dictionaries, sets are dictionaries and many more.In this course we’ll take an in-depth look at:associative arrays and how they can be implemented using hash mapshash functions and how we can leverage them for our own custom classesPython dictionaries and sets and the various operations we can perform with themspecialized dictionary structures such  as OrderedDict and how it relates to the built-in Python3.6+ dictPython’s implementation of multi-sets, the Counter classthe ChainMap classhow to create custom dictionaries by inheriting from the UserDict classhow to serialize and deserialize dictionaries to JSONthe use of schemas in custom JSON deserializationa brief introduction to some useful libraries such as JSONSchema, Marshmallow, PyYaml and Serpy***** Prerequisites *****Please note that this is a relatively advanced Python course, and a strong knowledge of some topics in Python is required.Beyond the basics of Python (loops, conditional statements, exception handling, built-in data types, creating classes, etc), you should also have an in-depth understanding of the following topics:functions and functional programming (recursion, *args, **kwargs, zip, map, sorted, any, all, etc)lambdas, closures and decorators (including standard decorators such as @singledispatch, @wraps, etc)iterables, iterators, generators and context managersnamed tuplesvariable scopes and namespaces (globals, locals, etc)For this course you will also need to install some 3rd party libraries, so you need to be comfortable with doing this using the tool of your choice (e.g. pip, conda, etc)Finally, most of the code in this course is illustrated using the freely available  Jupyter Notebooks, so you will need that as well.Who this course is for:Python developers who want a deeper understanding of Python dictionaries and related topicsGet Python 3: Deep Dive (Part 3 – Hash Maps) downloadPurchase Python 3: Deep Dive (Part 3 – Hash Maps) courses at here with PRICE $199 $38
