Marsilea is a Python library for creating composable visualizations in a declarative way. It is built on top of Matplotlib and provides a high-level API for you to puzzle different visualizations together like logo.

Graphene is a Python library for building GraphQL schemas/types. A GraphQL schema describes your data model, and provides a GraphQL server with an associated set of resolve methods that know how to fetch data.

The pyspnego Python library handles Negotiate, NTLM, Kerberos (SPNEGO) and CredSSP authentication. It also includes a packet parser that can be used to decode raw NTLM/SPNEGO/Kerberos tokens into a human readable format.

PetroFit is a package for calculating Petrosian properties, such as radii and concentration indices, as well as fitting galaxy light profiles. In particular, PetroFit includes tools for performing accurate photometry, segmentations, Petrosian profiling, and Sérsic fitting.

Schedule is an in-process scheduler for periodic jobs that uses the builder pattern for configuration. Schedule lets you run Python functions (or any other callable) periodically at pre-determined intervals using a simple, human-friendly syntax.

A pure-python universal errors-and-erasures Reed-Solomon Codec, based on the tutorial at Wikiversity. This is a burst-type implementation, so that it supports any Galois field higher than 2^3, but not binary streams.

Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork worker model. The Gunicorn server is broadly compatible with various web frameworks, simply implemented, light on server resources, and fairly speedy.

aiomysql is a driver for accessing a MySQL database from the asyncio Python framework. It depends on and reuses most parts of PyMySQL. aiomysql tries to preserve the same API as the aiopg library.

Paramiko is a python implementation of the SSHv2 protocol, providing both client and server functionality. While it leverages a Python C extension for low level cryptography (PyCrypto), Paramiko itself is a pure Python interface around SSH networking concepts.

wsgiprox is a Python WSGI (Web Server Gateway Interface) middle-ware for adding HTTP and HTTPS proxy support to a WSGI application. The library accepts HTTP and HTTPS proxy connections, and routes them to a designated prefix.

This package is a tool for cross-compiling extension modules. It creates a special virtual environment such that pip or setup.py will cross compile packages for you, usually with no further work on your part.

The apptools project provides a set of packages that Enthought has found useful in creating a number of applications. It includes features such as a filesystem abstraction, convenience functions for creating loggers, or an application preference manager.

The goal of pathlib2 is to provide a backport of the standard pathlib module which tracks the standard library module, so all the newest features of the standard pathlib can be used also on older Python versions.

This package provides a functionality for working with user perceived characters. More specifically, string manipulation and calculation functions for working with grapheme cluster groups (graphemes) as defined by the Unicode Standard Annex #29.

This package provides helpers for computing similarities between arbitrary sequences. Included metrics are Levenshtein, Hamming, Jaccard, and Sorensen distance, plus some bonuses. All distance computations are implemented in pure Python, and most of them are also implemented in C.

This package provides a Python implementation of John Gruber's Markdown. The library features international input, various Markdown extensions, and several HTML output formats. A command line wrapper markdown_py is also provided to convert Markdown files to HTML.

Paramiko is a python implementation of the SSHv2 protocol, providing both client and server functionality. While it leverages a Python C extension for low level cryptography (PyCrypto), Paramiko itself is a pure Python interface around SSH networking concepts.

Python scripts to find enrichment of GO terms. In addition, this package is used for processing the obo-formatted file from Gene Ontology website. The data structure is a directed acyclic graph that allows easy traversal from leaf to root.

schwifty is a Python library that let's you easily work with IBANs and BICs as specified by the ISO. IBAN is the Internation Bank Account Number and BIC the Business Identifier Code. Both are used for international money transfer.

SLEPc, the Scalable Library for Eigenvalue Problem Computations, is based on PETSc, the Portable, Extensible Toolkit for Scientific Computation. It employs the MPI standard for all message-passing communication. slepc4py provides Python bindings to almost all functions of SLEPc.

PyMCubes is an implementation of the marching cubes algorithm to extract iso-surfaces from volumetric data. The volumetric data can be given as a three-dimensional NumPy array or as a Python function f(x, y, z).

Greenlet package is a spin-off of Stackless, a version of CPython that supports micro-threads called "tasklets". Tasklets run pseudo-concurrently (typically in a single or a few OS-level threads) and are synchronized with data exchanges on "channels".
