awesome-python-decorator

This page largely documents the history of the process of adding decorators to Python

This page is meant to be a central repository of decorator code pieces. Lots of decorator examples, really cool!

A decorator indicating abstract methods

A subclass of the built-in , indicating an abstract property

Decorator to mark generator-based coroutines. New in version 3.4

Register func as a function to be executed at termination

Return a class method for function

Define a factory function for with statement context managers, without needing to create a class or separate and methods

Transform a method of a class into a property whose value is computed once and then cached as a normal attribute for the life of the instance

Decorator to wrap a function with a memoizing callable that saves up to the maxsize most recent calls. It can save time when an expensive or I/O bound function is periodically called with the same arguments. New in python 3.2

Transforms a function into a single-dispatch generic function. New in python 3.4

Given a class defining one or more rich comparison ordering methods, this class decorator supplies the rest

This is a convenience function for invoking update_wrapper() as a function decorator when defining a wrapper function

Return a property attribute

Return a static method for function

This function transforms a generator function into a coroutine function which returns a generator-based coroutine. New in python 3.5

Acts as a function decorator, class decorator or a context manager. Inside the body of the function or with statement, the target is patched with a new object. When the function/with statement exits the patch is undone. New in python 3.3

Patch a dictionary, or dictionary like object, and restore the dictionary to its original state after the test. New in python 3.3

Perform multiple patches in a single call. New in python 3.3

Patch the named member (attribute) on an object (target) with a mock object. New in python 3.3

cached-property

A decorator for caching properties in classes

cachetools

This module provides various memoizing collections and decorators, including variants of the Python 3 Standard Library @lru_cache function decorator

celery

Celery is a distributed task queue, it uses decorator to create tasks

click

Click is a Python package for creating beautiful command line interfaces, based on declaring commands through decorators. You can also check out the library which shares a similar idea with click

deco

A simplified parallel computing model for Python. DECO automatically parallelizes Python programs, and requires minimal modifications to existing serial programs

decorator

This is your best option if you want to preserve the signature of decorated functions in a consistent way across Python releases

deprecated

Use decorator to deprecate old python classes, functions or methods. Decorators can also be used to add Sphinx directives

fasteners

Provides useful locks and decorators to lock/unlock around functions and methods

flask

Flask is a micro web framework in python, which uses decorators to route the URL, register error handler, register processor and so on

flask-login

Flask-Login provides user session management for Flask. For example, it use the decorator to protect some views that need the user to be logged in

GB2260.py

This project is used to look up Chinese administrative divisions. It uses decorators to write Python 2.x and 3.x compatible code

marshmallow

A lightweight library for converting complex objects to and from simple Python datatypes. It use decorators to register schema pre-processing and post-processing methods

me-api

An extensible, personal API with custom integrations. It uses a decorator to make sure there is an access_token in the configuration file before sending the API request and reject another authentication if there is already an access_token

Numba gives you the power to speed up your applications with high performance functions written directly in Python. It uses to decorate array-oriented and math-heavy Python code can be just-in-time compiled to native machine instructions, similar in performance to C, C++ and Fortran, without having to switch languages or Python interpreters

lettuce

Lettuce is a BDD tool for python. It uses and to decorate functions and classes so they become new step definitions

profilehooks

Python decorators for profiling/tracing/timing a single function

pypi-cli

pypi-cli is a command-line interface to the Python Package Index. It use decorator to makes a property lazy-evaluated

py-spin

py-spin is a terminal spinner package for python. Yes, it does use a decorator to register a function that needs to take a long time to finish, as well as showing a spinner while it's processing!

python-goto

A function decorator that rewrites the bytecode, enabling goto in python

showme

ShowMe is a simple set of extremely useful function decorators for Python. It allows you to view trace information, execution time, cputime, and function documentation

tenacity

Simplifies the task of adding retry behavior to just about anything. It originates from a fork of

timeout-decorator

Timeout decorator for Python which uses a decorator to limit the execution time of the given function

Tomorrow

Tomorrow use decorator to do the magic that let you write asynchronous code with ease

wrapt

A Python module for decorators, wrappers and monkey patching
