Django-filter is a generic, reusable application to alleviate writing some of the more mundane bits of view code. Specifically, it allows users to filter down a queryset based on a model’s fields, displaying the form to let them do this.

This package provides a text progress bar library for Python. This version only differs from the original progressbar package in that it uses relative package imports instead of absolute imports, which is necessary for the module to work under Python 3.3.

SocksiPyChain is a modified version of the SocksiPy SOCKS module, which adds support for arbitrary chaining of proxy servers and various modes of TLS/SSL encryption. It was developed for use in PageKite, and also includes a simple netcat replacement with chaining support.

This package provides a Sphinx extension for linking to a project's issue tracker. This includes roles for linking to issues, pull requests and user profiles. Support for GitHub is built-in, but other services can also be supported with sphinx-issues.

Pandas 0.23 added a simple API for registering accessors with Pandas objects. Pandas-flavor extends Pandas' extension API by

• adding support for registering methods as well

• making each of these functions backwards compatible with older versions of Pandas

Flask-Limiter adds rate limiting to Flask applications. Rate limits can be configured at different levels such as:

• Application wide global limits per user

• Default limits per route

• By blueprints

• By class-based views

• By individual routes

Wadler-Lindig is a minimal, zero-dependency pretty-printing library for Python that implements a simplified version of the Wadler-Lindig algorithm. Designed to consume less horizontal space than Python's built-in pprint.pprint, it produces compact, well-formatted representations even for complex custom types.

SeaSurf is a Flask extension for preventing cross-site request forgery (CSRF). CSRF attacks are problematic because the mechanism they use is relatively easy to exploit. This extension attempts to aid you in securing your application from such attacks. This extension is based on the Django middleware.

The functions and classes in humanfriendly can be used to make text interfaces more user-friendly. It includes tools to parse and format numbers, file sizes, and timespans, timers for long-running operations, menus to allow the user to choose from a list of options, and terminal interaction helpers.

xdg-base-dirs is a Python module that provides functions to return paths to the directories defined by the XDG Base Directory Specification, to save you from duplicating the same snippet of logic in every Python utility you write that deals with user cache, configuration, or data files.

This is a library to allow the easy creation of Relay-compliant servers using the GraphQL Python reference implementation of a GraphQL server. It should be noted that the code is a exact port of the original graphql-relay js implementation from Facebook.

This is Python port of linkify-it, which is a links recognition library with full Unicode support. It has features like:

• Full unicode support, with astral characters

• International domains support

• Allows rules extension and custom normalizers.

The h5py package provides both a high- and low-level interface to the HDF5 library from Python. The low-level interface is intended to be a complete wrapping of the HDF5 API, while the high-level component supports access to HDF5 files, datasets and groups using established Python and NumPy concepts.

Scikit-rebate is a scikit-learn-compatible Python implementation of ReBATE, a suite of Relief-based feature selection algorithms for Machine Learning. These algorithms excel at identifying features that are predictive of the outcome in supervised learning problems, and are especially good at identifying feature interactions that are normally overlooked by standard feature selection algorithms.

This package provides line_profiler - a Python module for doing line-by-line profiling of functions. kernprof is a convenient script for running either line_profiler or the Python standard library's cProfile or profile modules, depending on what is available. It's a successor of https://github.com/rkern/line_profiler.

python-secretstorage provides a way for securely storing passwords and other secrets. It uses D-Bus Secret Service API that is supported by GNOME Keyring (since version 2.30) and KSecretsService. SecretStorage supports most of the functions provided by Secret Service, including creating and deleting items and collections, editing items, locking and unlocking collections (asynchronous unlocking is also supported).

This is a backport of the subprocess standard library module from Python 3.2 and 3.3 for use on Python 2. It includes bugfixes and some new features. On POSIX systems it is guaranteed to be reliable when used in threaded applications. It includes timeout support from Python 3.3 but otherwise matches 3.2’s API.

The simplegeneric module lets you define simple single-dispatch generic functions, akin to Python’s built-in generic functions like len(), iter() and so on. However, instead of using specially-named methods, these generic functions use simple lookup tables, akin to those used by e.g. pickle.dump() and other generic functions found in the Python standard library.

The rpy2 package is a namespace package. This is the part of that package that covers the "high-level" interface to R used in rpy2. It uses the "low-level" interface (bindings to R's C API) to create a more Pythonic and safer interface in rpy2.robjects as well as extentions for ipython and jupyter notebooks in rpy2.ipython.

This hook sends emails describing changes introduced by pushes to a Git repository. For each reference that was changed, it emits one ReferenceChange email summarizing how the reference was changed, followed by one Revision email for each new commit that was introduced by the reference change.

This script is designed to be used as a post-receive hook in a Git repository

This package implements RetryClient for aiohttp to retry connection to provided endpoint with timeouts logic or use:

• ExponentialRetry with exponential backoff

• RandomRetry for random backoff

• ListRetry with backoff you predefine by list

• FibonacciRetry with backoff that looks like fibonacci sequence

• JitterRetry exponential retry with a bit of randomness

SunPy is package for solar physics and is meant to be a free alternative to the SolarSoft data analysis environment.

It includes an interface for searching and downloading data from multiple data providers, data containers for image and time series data, commonly used solar coordinate frames and associated transformations, as well as other functionality needed for solar data analysis.

This package supports the efficient creation of hookable objects, which are callable objects that are meant to be optionally replaced. The idea is that you create a function that does some default thing and make i hookable. Later, someone can modify what it does by calling its sethook method and changing its implementation. All users of the function, including those that imported it, will see the change.

Python bindings for the C++ implementation of the Mapbox Earcut library, which provides very fast and quite robust triangulation of 2D polygons.

The library implements a modified ear slicing algorithm, optimized by z-order curve hashing and extended to handle holes, twisted polygons, degeneracies and self-intersections in a way that doesn't guarantee correctness of triangulation, but attempts to always produce acceptable results for practical data like geographical shapes.
