Type aliases are user-specified types which may be as complex as any type hint, and are specified with a simple variable assignment on a module top level.| Python Enhancement Proposals (PEPs)
Source code: Lib/types.py This module defines utility functions to assist in dynamic creation of new types. It also defines names for some object types that are used by the standard Python interpre...| Python documentation
Function overloading¶| mypy.readthedocs.io
Source code: Lib/_collections_abc.py This module provides abstract base classes that can be used to test whether a class provides a particular interface; for example, whether it is hashable or whet...| Python documentation
Defining generic classes¶| mypy.readthedocs.io
Source code: Lib/typing.py This module provides runtime support for type hints. Consider the function below: The function surface_area_of_cube takes an argument expected to be an instance of float,...| Python documentation
Source code: Lib/collections/__init__.py This module implements specialized container datatypes providing alternatives to Python’s general purpose built-in containers, dict, list, set, and tuple.,,...| Python documentation
This chapter explains the meaning of the elements of expressions in Python. Syntax Notes: In this and the following chapters, extended BNF notation will be used to describe syntax, not lexical anal...| Python documentation
Protocols and structural subtyping¶| mypy.readthedocs.io
PEP 3107 introduced syntax for function annotations, but the semantics were deliberately left undefined. There has now been enough 3rd party usage for static type analysis that the community would benefit from a standard vocabulary and baseline tools w...| Python Enhancement Proposals (PEPs)
The Python interpreter has a number of functions and types built into it that are always available. They are listed here in alphabetical order.,,,, Built-in Functions,,, A, abs(), aiter(), all(), a...| Python documentation
