attrs is a Python package with class decorators that ease the chores of implementing the most common attribute-related object protocols.

This is an implementation of ASN.1 types and codecs in Python. It is suitable for a wide range of protocols based on the ASN.1 specification.

retry is an easy to use retry decorator for Python. It can be used to retry a function a given number of times.

Beautiful Soup is a Python library designed for rapidly setting up screen-scraping projects. It offers Pythonic idioms for navigating, searching, and modifying a parse tree, providing a toolkit for dissecting a document and extracting what you need. It automatically converts incoming documents to Unicode and outgoing documents to UTF-8.

Cloudpickle makes it possible to serialize Python constructs not supported by the default pickle module from the Python standard library. It is especially useful for cluster computing where Python expressions are shipped over the network to execute on remote hosts, possibly close to the data.

NumPy is the fundamental package for scientific computing with Python. It contains among other things: a powerful N-dimensional array object, sophisticated (broadcasting) functions, tools for integrating C/C++ and Fortran code, useful linear algebra, Fourier transform, and random number capabilities.

Dulwich is an implementation of the Git file formats and protocols written in pure Python.

This package provides a tool for modifying a user's PATH.

Roifile is a Python library to read, write, create, and plot ImageJ ROIs, an undocumented and ImageJ application specific format to store regions of interest, geometric shapes, paths, text, etc for image overlays.

A library to identify devices (phones, tablets) and their capabilities by parsing (browser/HTTP) user agent strings.

Senf introduces a new platform native string type called fsnative. It adds functions to convert text, bytes and paths to and from that new type and helper functions to integrate it nicely with the Python stdlib.

The aim of the decorator module is to simplify the usage of decorators for the average programmer, and to popularize decorators usage giving examples of useful decorators, such as memoize, tracing, redirecting_stdout, locked, etc. The core of this module is a decorator factory.

This is a plugin for the Python code checking tool Flake8 to encourage correct string literal concatenation.

It looks for style problems like implicitly concatenated string literals on the same line (which can be introduced by the code formatting tool Black), or unnecessary plus operators for explicit string literal concatenation.

The aim of Kombu is to make messaging in Python as easy as possible by providing an idiomatic high-level interface for the AMQ protocol, and also provide proven and tested solutions to common messaging problems. AMQP is the Advanced Message Queuing Protocol, an open standard protocol for message orientation, queuing, routing, reliability and security, for which the RabbitMQ messaging server is the most popular implementation.

text-unidecode is a basic Python port of the Text::Unidecode Perl library. It can create ASCII representations of Unicode data. In general users should prefer the python-unidecode package which offers better memory usage and transliteration quality.

Biblib provides a simple, standalone Python 3 package for parsing BibTeX bibliographic databases, as well as algorithms for manipulating BibTeX entries in BibTeX-y ways. Biblib's parser is derived directly from the WEB source code for BibTeX and hence (barring bugs in translation) should be fully compatible with BibTeX's own parser.

python-astroid provides a common base representation of Python source code for projects such as pychecker, pyreverse, pylint, etc. It provides a compatible representation which comes from the _ast module. It rebuilds the tree generated by the builtin _ast module by recursively walking down the AST and building an extended ast. The new node classes have additional methods and attributes for different usages. They include some support for static inference and local name scopes. Furthermore, astroid builds partial trees by inspecting living objects.

Beautiful Soup is a Python library designed for rapidly setting up screen-scraping projects. It offers Pythonic idioms for navigating, searching, and modifying a parse tree, providing a toolkit for dissecting a document and extracting what you need. It automatically converts incoming documents to Unicode and outgoing documents to UTF-8.

This package helps wrapping dynamic libraries in Python. It includes a pure-Python C parser and an automation library that uses C header file definitions to simplify the use of C bindings.

This package implements rich tables for various purposes, it's JSON human-prettifier based on the rich Python library.

This package contains a plugin that provides specializations for type hinting stub files, especially interesting for linting typeshed. It adds the .pyi extension to the default value of the --filename command-line argument to Flake8. This means stubs are linted by default with this plugin enabled, without needing to explicitly list every file. It modifies PyFlakes runs for .pyi files to defer checking type annotation expressions after the entire file has been read. This enables support for first-class forward references that stub files use.

This package provides miscellaneous path functions for Python.

The EditorConfig project consists of a file format for defining coding styles and a collection of text editor plugins that enable editors to read the file format and adhere to defined styles. EditorConfig files are easily readable and they work nicely with version control systems.

This library provides a streaming wrapper around python tarfile and allow secure handling files and support encryption.
