 Python is a dynamically typed language, and some of its appeal derives from 
this. Nevertheless, especially for large code bases, it would be nice if a 
compiler could find type errors before the code is even run. Optional static 
type checking promises exactly this, and over the past four years we have 
successfully introduced this feature into Python 3. This talk introduces the 
type system we've adopted and the syntax used for type annotations, some tips 
on how to get started with a large existing code base, and our experience 
using the 'mypy' type checker at Dropbox. The entire system is open source, 
and has also been adopted by other companies such as Lyft, Quora and Facebook.
