Cymem provides two small memory-management helpers for Cython. They make it easy to tie memory to a Python object's life-cycle, so that the memory is freed when the object is garbage collected.

SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible.

Gcovr provides a utility for managing the use of the GNU gcov utility and generating summarized code coverage results. It is inspired by the Python coverage.py package, which provides a similar utility for Python.

Six is a Python 2 and 3 compatibility library. It provides utility functions for smoothing over the differences between the Python versions with the goal of writing Python code that is compatible on both Python versions.

The Python Imaging Library (PIL) adds image processing capabilities to your Python interpreter. This library supports many file formats, and provides powerful image processing and graphics capabilities.

NOTE: This package is superseded by python-pillow

Flask is a micro web framework based on the Werkzeug toolkit and Jinja2 template engine. It is called a micro framework because it does not presume or force a developer to use a particular tool or library.

rpy2 is a redesign and rewrite of rpy. It is providing a low-level interface to R from Python, a proposed high-level interface, including wrappers to graphical libraries, as well as R-like structures and functions.

This library provides functions which take in UFO objects (such as Defcon Fonts or Robofab RFonts) and converts any cubic curves to quadratic. The most useful function is probably fonts_to_quadratic.

Voilà turns Jupyter notebooks into standalone web applications. Unlike the usual HTML-converted notebooks, each user connecting to the Voilà tornado application gets a dedicated Jupyter kernel which can execute the callbacks to changes in Jupyter interactive widgets.

Sanic is a Python web server and web framework that's written to go fast. It allows the usage of the async/await syntax added in Python 3.5, which makes your code non-blocking and speedy.

Pyro enables you to build applications in which objects can talk to each other over the network. You can just use normal Python method calls to call objects on other machines, also known as remote procedure calls (RPC).

AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio or trio. It implements trio-like structured concurrency on top of asyncio, and works in harmony with the native SC of trio itself.

Babel is composed of two major parts: - tools to build and work with gettext message catalogs - a Python interface to the CLDR (Common Locale Data Repository), providing access to various locale display names, localized number and date formatting, etc.

Lcapy is a Python package for linear circuit analysis. It uses SymPy for symbolic mathematics.

Lcapy can symbolically analyse circuits described with netlists or by series/parallel combinations of components. It can also manipulate ontinuous-time and discret-time expressions.

This library provides a way to check examples in your code and documentation by parsing them from their source and evaluating the parsed examples as part of your normal test run. Integration is provided for the main Python test runners.

PyOTP is a Python library for generating and verifying one-time passwords. It can be used to implement two-factor (2FA) or multi-factor (MFA) authentication methods in web applications and in other systems that require users to log in.

This package provides a Python interface the libVEX and VEX IR. VEX is the intermediate representation (also known as intermediate language) used by the Valgrind analysis tool. As such, VEX is designed to enable all kinds of binary analysis tasks.

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.

Nose2 is the next generation of nicer testing for Python, based on the plugins branch of unittest2. Nose2 aims to improve on nose by providing a better plugin api, being easier for users to configure, and simplifying internal interfaces and processes.

geopy is a Python client for several popular geocoding web services. geopy makes it easy for Python developers to locate the coordinates of addresses, cities, countries, and landmarks across the globe using third-party geocoders and other data sources.

Clang is a compiler front end for the C, C++, Objective-C and Objective-C++ programming languages. It uses LLVM as its back end. The Clang project includes the Clang front end, the Clang static analyzer, and several code analysis tools.
