pycares is a Python module which provides an interface to c-ares, a C library that performs DNS requests and name resolutions asynchronously.

PyPugJS is a high-performance port of PugJS for Python, that converts any .pug source into different template languages: Django, Jinja2, Mako, and Tornado.

This library can extract RDFa 1.1 from (X)HTML, SVG, or XML. It can produce serialized versions of the extracted graph, or an RDFLib Graph.

This library provides a Pythonic API wrapper for the reference Arrow C++ implementation, along with tools for interoperability with pandas, NumPy, and other traditional Python scientific computing packages.

The PyPrind (Python Progress Indicator) module provides a progress bar and a percentage indicator object that let you track the progress of a loop structure or other iterative computation.

pywinrm is a Python client for the Windows Remote Management (WinRM) service. It allows you to invoke commands on target Windows machines from any machine that can run Python.

pyquery allows you to make jQuery queries on xml documents. The API is as much as possible the similar to jQuery. pyquery uses lxml for fast xml and html manipulation.

PyKafka is a client for the Apache Kafka distributed messaging system. It includes Python implementations of Kafka producers and consumers, which are optionally backed by a C extension built on librdkafka.

The pyscard smart card library is a framework for building smart card aware applications in Python. The smart card module is built on top of the PCSC API Python wrapper module.

pylibmc is a client in Python for memcached. It is a wrapper around TangentOrg’s libmemcached library, and can be used as a drop-in replacement for the code{python-memcached

This package provides efficient Python bindings to picosat on the C level. When importing pycosat, the picosat solver becomes part of the Python process itself. picosat is a Boolean Satisfiability Problem (SAT) solver.

Pybox2d is a 2D physics library for your games and simple simulations. It's based on the Box2D library, written in C++. It supports several shape types (circle, polygon, thin line segments), and quite a few joint types (revolute, prismatic, wheel, etc.).

Pythran is an ahead of time compiler for a subset of the Python language, with a focus on scientific computing. It takes a Python module annotated with a few interface descriptions and turns it into a native Python module with the same interface, but (hopefully) faster.

Pyliblo is a Python wrapper for the liblo Open Sound Control (OSC) library. It supports almost the complete functionality of liblo, allowing you to send and receive OSC messages using a nice and simple Python API. Also included are the command line utilities send_osc and dump_osc.

This library allows you to create a system tray icon. It makes it possible to specify an icon, a title and a callback for when the icon is activated. The icon and title can be changed after the icon has been created, and the visibility of the icon can be toggled.

PySAML2 is a pure python implementation of SAML Version 2 Standard. It contains all necessary pieces for building a SAML2 service provider or an identity provider. The distribution contains examples of both.

This package was originally written to work in a WSGI environment, but there are extensions that allow you to use it with other frameworks.

PyTorch is a Python package that provides two high-level features:

• tensor computation (like NumPy) with strong GPU acceleration;

• deep neural networks (DNNs) built on a tape-based autograd system.

You can reuse Python packages such as NumPy, SciPy, and Cython to extend PyTorch when needed.

Note: currently this package does not provide GPU support.

python-pymonad implements data structures typically available in purely functional or functional first programming languages such as Haskell and F#. Included are

• Monad and Monoid data types with several common monads such as Maybe and State

• Useful tools such as the @curry decorator for defining curried functions

• Type annotations to help ensure correct usage

PyVista is...

• Pythonic VTK: a high-level API to the Visualization Toolkit (VTK);

• mesh data structures and filtering methods for spatial datasets;

• 3D plotting made simple and built for large/complex data geometries.

This package provides a Pythonic, well-documented interface exposing VTK's powerful visualization backend to facilitate rapid prototyping, analysis, and visual integration of spatially referenced datasets.

Pympler is a development tool to measure, monitor and analyze the memory behavior of Python objects in a running Python application.

By pympling a Python application, detailed insight in the size and the lifetime of Python objects can be obtained. Undesirable or unexpected runtime behavior like memory bloat and other pymples can easily be identified.

A web profiling frontend exposes process statistics, garbage visualisation and class tracker statistics.
