Cheat sheets can be really helpful when you’re trying a set of exercises related to a specific topic, or working on a project. Because you can only fit so much information on a single sheet of paper, most cheat sheets are a simple listing of syntax rules.

Cheat Sheet For Python

Twitter: @ehmatthes

This document is a quick cheat sheet showing how the PEP 484 typeannotation notation represents various common types in Python 3.

Note

Technically many of the type annotations shown below are redundant,because mypy can derive them from the type of the expression. Somany of the examples have a dual purpose: show how to write theannotation, and show the inferred types.

Variables¶

Python 3.6 introduced a syntax for annotating variables in PEP 526and we use it in most examples.

Built-in types¶

Functions¶

Python 3 supports an annotation syntax for function declarations.

Standard “duck types”¶

In typical Python code, many functions that can take a list or a dictas an argument only need their argument to be somehow “list-like” or“dict-like”. A specific meaning of “list-like” or “dict-like” (orsomething-else-like) is called a “duck type”, and several duck typesthat are common in idiomatic Python are standardized.

You can even make your own duck types using Protocols and structural subtyping.

Classes¶

Coroutines and asyncio¶

See Typing async/await for the full detail on typing coroutines and asynchronous code.
