Target Audiences

Beginners and intermediates who want to know the mechanics and purpose of types and type systems in Python

Developers who want to learn the proper terminology to make discussing code in your team and searching for information online more efficient

It is easy to forget about types in Python. After all, you type a equals 10 and it just works. No need to tell python the type of a. But actually, behind the simplicity of the Python language, there is a very sophisticated type system. In fact, Python has a combination of different type systems as you will learn in this course.

You might wonder…why learn types at all? Surely you already know how to work with types in python! It is entirely possible to use types every day without understanding the mechanics behind them. But as with everything else in software engineering, once you learn HOW and WHY it works, you can make more informed choices when designing your systems.

Target audience

Developers who especially benefit from this course, are:

Beginners and intermediates who want to know the mechanics and purpose of types and type systems in Python
Software engineers who want to use the type system as an extra development tool by adding type hints to improve their code quality
Developers who want to learn the proper terminology to make discussing code in your team and searching for information online more efficient

Challenges

Python is an easy language to learn. It hides many of the nuances about data types. But when developers get more experienced, they are more confronted with Python’s unique way to create, instantiate and work with data types. It is at this moment where it helps to take a deep dive into Types and Type Systems.

What can you do after this course?

Fix bugs faster by understanding error messages better
Prevent common type problems by knowing type system techniques
Make classes more efficient by using Python’s unique language features
Create clean modular design by using Protocol classes and type hints
Discuss pro’s and con’s of proposed solutions by learning proper technical terms
Make the transition from another language to Python more efficient

Topics

Introduction to type systems: Type system categories and their basic building blocks: types.
Implicit vs. explicit typing: Literals, variables and attributes.
Dynamic vs. static typing: Duck typing, Python protocols and the Python Datamodel, Compilers and interpreters.
Type Hints: Annotations, static type checkers, kind of types, special typing constructs.
Type flexibility: Safe, sound, complete. Promotion, conversion and comparison.
Nominal vs. structural typing: Using composite classes and protocols to design interfaces for modular systems.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
