A practical introduction to Python's type annotation features (and the typing module), via simple, hackable examples.
(The examples currently use the typing syntax introduced in Python 3.6 - Backwards-compatible Python 2 examples may be added in a future update.)
These examples are intended to be self-explanatory to a Python developer, with minimal setup.
In addition to Python 3.6+, you'll also need the mypy type validator installed to experiment with the provided code:
pip install mypy
(optionally, inside a virtualenv or other environment wrapper, to keep this from affecting your local Python libraries!)
Once you've got all the requirements in place, you should be able to simply run
mypy examples/
In the base folder, and see a confirmation message like Success: no issues found in 18 source files.
You can now begin the tutorial track here:
(There are currently 16 examples, but only a few have detailed tutorials at the moment - I hope to improve this in the near future!)
If you have any feedback, questions, or Typing features you'd like to see covered, please let me know on Pluralsight Slack as @david.sturgis, or via GitHub Issues (or a PR) on this repo. Thanks!
