New Book Release: Python Typing
I am happy to announce that my latest book, Python Typing, is now available on all platforms. You can get your copy on Gumroad or Leanpub or Amazon
Python has had type hinting support since Python 3.5, over TEN years ago! However, Python’s type annotations have changed repeatedly over the years. In Python Typing: Type Checking for Python Programmers, you will learn all you need to know to add type hints to your Python applications effectively.
You will also learn how to use Python type checkers, configure them, and set them up in pre-commit or GitHub Actions. This knowledge will give you the power to check your code and your team’s code automatically before merging, hopefully catching defects before they make it into your products.
What You’ll Learn
You will learn all about Python’s support for type hinting (annotations). Specifically, you will learn about the following topics:
Variable annotations
Function annotations
Type aliases
New types
Generics
Hinting callables
Annotating TypedDict
Annotating Decorators and Generators
Using Mypy for type checking
Mypy configuration
Using ty for type checking
ty configuration
and more!
