Mypy-thon gives you wings!


As your python project grows and the number of contributors increases, the stability, readability and usability of your code-base can diminish. The once expressive experience of a single author writing dynamically typed Python can turn into a real headache as the complexity of your system develops.

But Python can still be a great choice for large applications - the library’s for scientific applications and web API’s are well documented, open-source and have been in development for decades. Mypy is a tool that (pretty much) allows you to have your cake and eat it. By combining the convenience and maturity of Python with a powerful type system and compile-time checking, you can make your project incredibly easy to read, debug and test for all contributors.

My talk will summarise the main features of Mypy and will also give you a head start on how to convert (and maintain) an existing code-base to include static annotations.
