Python Type Hints | NP-Incompleteness
Jukka Lehtosalo is a Finnish Software Engineer at Dropbox. He developed an optional type system for Python, mypy, during his PhD thesis in Cambridge. After meeting in a Python conference, Guido van Rossum (creator of Python) invited Lehtosalo to join him at Dropbox. They started adopting mypy in real use cases during a Hackathon, which led to mypy being one of the most popular Python type checkers
Python Types Intro - FastAPI
Python Types Intro¶ Python has support for optional "type hints" (also called "type annotations"). These "type hints" or annotations are a special syntax that allow declaring the type of a variable. By declaring types for your variables, editors and tools can give you better support. This is just a quick tutorial / refresher about Python type hints. It covers only the minimum necessary to use them

NOTE: We are in the process of moving the mypyc README to the mypyc repository This may be out of date! Mypyc is a compiler that compiles mypy-annotated, statically typed Python modules into CPython C extensions. Currently our primary focus is on making mypy faster through compilation -- the default mypy wheels are compiled with mypyc. Compiled mypy is about 4x faster than without compilation. Myp

Our journey to type checking 4 million lines of Python
Dropbox is a big user of Python. It’s our most widely used language both for backend services and the desktop client app (we are also heavy users of Go, TypeScript, and Rust). At our scale—millions of lines of Python—the dynamic typing in Python made code needlessly hard to understand and started to seriously impact productivity. To mitigate this, we have been gradually migrating our code to stati
the state of type hints in Python
One of the main selling points for Python is that it is dynamically-typed. There is no plan to change this. Nevertheless, in September 2014 Guido van Rossum (Python BDFL) created a python enhancement proposal (PEP-484) to add type hints to Python. It has been released for general usage a year later, in September 2015, as part of Python 3.5.0. Twenty-five years into its existence now there was a st
Python Type Checking (Guide) – Real Python
Watch Now This tutorial has a related video course created by the Real Python team. Watch it together with the written tutorial to deepen your understanding: Python Type Checking In this guide, you will get a look into Python type checking. Traditionally, types have been handled by the Python interpreter in a flexible but implicit way. Recent versions of Python allow you to specify explicit type h
A Python static typing update [LWN.net]
One of the larger features added to Python over the last few releases is support for static typing in the language. Static type-checking and tools to support it show up frequently as topics at the Python Language Summit (PLS) and this year was no exception. Mypy developers Jukka Lehtosalo and Ivan Levkivskyi gave an update on static typing at PLS 2018. Lehtosalo started things off by talking about
