The cysignals package provides mechanisms to handle interrupts (and other signals and errors) in Cython code, using two related approaches, for mixed Cython/Python code or external C libraries and pure Cython code, respectively.

This package is a parser for Coffeescript Object Notation (CSON).

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.

This is a package for matrices describing the affine transformation of the plane.

This package provides a Python module that displays numbers and dates in "human readable" forms. For example, it would display "12345591313" as "12.3 billion".

perfplot extends Python's timeit by testing snippets with input parameters (e.g., the size of an array) and plotting the results.

This is a library to support the Internationalised Domain Names in Applications (IDNA) protocol as specified in RFC 5891. This version of the protocol is often referred to as “IDNA2008” and can produce different results from the earlier standard from 2003. The library is also intended to act as a suitable drop-in replacement for the “encodings.idna” module that comes with the Python standard library but currently only supports the older 2003 specification.

ipdb exports functions to access the IPython debugger, which features tab completion, syntax highlighting, better tracebacks and better introspection than Python's standard pdb debugger, with which it shares the same interface.

This package provides a fast markdown parser in pure Python.

Pycparser is a complete parser of the C language, written in pure Python using the PLY parsing library. It parses C code into an AST and can serve as a front-end for C compilers or analysis tools.

Archspec offers human-readable labels for system architecture aspects. These aspects include CPU, network fabrics, etc. In addition, it offers APIs to detect, query, and compare them.

Include extension for Python Markdown. It lets you include local or remote (downloadable) files into your markdown at arbitrary positions.

This project is motivated by markdown-include and provides the same functionalities with some extras.

This package provides a module for generating v4 UUIDs and encoding them into 22 character URL-safe base64 slug representation.

This package provides a way to monitor file system events such as a file modification and trigger an action. This is similar to inotify, but portable.

This package provides an FFMPEG wrapper for working with video files. It implements generator functions for reading and writing data to and from FFMPEG, reliably terminating the process when done.

PyWavelets is a library for wavelet transforms in Python. Wavelets are mathematical basis functions that are localized in both time and frequency. Wavelet transforms are time-frequency transforms employing wavelets. They are similar to Fourier transforms, the difference being that Fourier transforms are localized only in frequency instead of in time and frequency.

This package provides a pure Python QR Code generator module. It uses the Python Imaging Library (PIL) to allow for the generation of QR Codes.

In addition this package provides a command line tool to generate QR codes and either write these QR codes to a file or do the output as ascii art at the console.

The fastbencode Python package implements the bencode serialization format for storing and transmitting loosely structured data, originally used by BitTorrent.

The format can encode four different types of values: byte strings, integers, lists, and dictionaries (associative arrays). It's simple and unaffected by endianness,

This package includes both a pure-Python version and an optional C extension based on Cython. Both provide the same functionality, but the C version has significantly better performance.

The SeleniumScreenshots library for Robot Framework provides keywords for annotating and cropping screenshots taken with SeleniumLibrary. It is useful for scripting automatically updated screenshots for documentation or for visual regression testing purposes.

Markupsafe provides an XML/HTML/XHTML markup safe string implementation for Python.

This package provides more-reasonable core functionality for numpy.

A lot of numpysane functionality is inspired by PDL (Perl Data Language).

numpysane has:

• easier broadcasting

• nicer array manipulation

• array concatenation

• manipulation of dimensions

• broadcast-aware inner product

• broadcast-aware outer product

• broadcast-aware 2-norm

• broadcast-aware matrix multiplication

This package provides a decorator for adding multiple argument dispatching to functions. The decorator creates a multimethod object as needed and registers the function with its annotations.

The Braintree Python SDK provides integration access to the Braintree Gateway. Braintree is a US-based payments service provider.

This package provides plugins for using apispec with web frameworks.
