We rely on the fact that despite the Python 3.5 stdlib typing does not contain Coroutine (or Awaitable), mypy doesn't actually appear to use the stdlib typing. Instead, when invoked it uses its own version of the typing module. So, as long as your mypy is up to date, it will ...
This module supports type hints as specified byPEP 484andPEP 526. The most fundamental support consists of the typesAny,Union,Tuple,Callable,TypeVar, andGeneric. typing模块支持类型提示,常见的类型有Any,Union,Tuple,Callable,TypeVar, andGeneric. 举例: def greeting(name: str) -> str: return 'Hello...
typing is a module that was introduced in Python 3.5 . The examples in PEP 484 rely on a Python 3+, and __annotations__ is a Python 3 concept. The backport can only allow to use the types of functions defined in the typing module, but it does not change the Python engine to magica...

In Python, 'typing' refers to type annotations that specify the type of data that our code can handle. For example, whether a variable is an integer, a string, or perhaps a more complex data structure, like dictionary. Typing is crucial because it clarifies what each part of your code is...
A backport of thetypingmodulefor older Python versions. It was removed after all Python versions that lacktypingin the standard library reached end of life. The last released version, supporting Python 2.7 and 3.4, isavailable at PyPI.
