The aim of Kombu is to make messaging in Python as easy as possible by providing an idiomatic high-level interface for the AMQ protocol, and also provide proven and tested solutions to common messaging problems. AMQP is the Advanced Message Queuing Protocol, an open standard protocol for message orientation, queuing, routing, reliability and security, for which the RabbitMQ messaging server is the most popular implementation.

This package implements a CAN matrix object in Python which describes the CAN-communication and its needed objects such as board units, frames, signals, and values. It also includes two command-line tools (canconvert and cancompare) for converting and comparing CAN databases.

Pyqrcode is a QR code generator written purely in Python with SVG, EPS, PNG and terminal output.

python-dbusmock allows for the easy creation of mock objects on D-Bus. This is useful for writing tests for software which talks to D-Bus services such as upower, systemd, logind, gnome-session or others, and it is hard (or impossible without root privileges) to set the state of the real services to what you expect in your tests.

folium makes it easy to visualize data that’s been manipulated in Python on an interactive leaflet map. It enables both the binding of data to a map for choropleth visualizations as well as passing rich vector/raster/HTML visualizations as markers on the map.

The library has a number of built-in tilesets from OpenStreetMap, Mapbox, and Stamen, and supports custom tilesets with Mapbox or Cloudmade API keys. It supports Image, Video, GeoJSON and TopoJSON overlays.

Biblib provides a simple, standalone Python 3 package for parsing BibTeX bibliographic databases, as well as algorithms for manipulating BibTeX entries in BibTeX-y ways. Biblib's parser is derived directly from the WEB source code for BibTeX and hence (barring bugs in translation) should be fully compatible with BibTeX's own parser.

This module is inspired by GNU bash's variable expansion features. It can be used as an alternative to Python's os.path.expandvars function. A good use case is reading config files with the flexibility of reading values from environment variables using advanced features like returning a default value if some variable is not defined.

Cachelib is a library extracted from werkzeug which provides a collection of cache libraries in the same API interface.

This package provides tools for plotting area-proportional two- and three-way Venn diagrams in matplotlib.

This library allows the user to define a command-line interface from a program's help message rather than specifying it programmatically with command-line parsers like getopt and argparse.

BibtexParser is a Python library to parse BibTeX files.

This package provides typing stubs for colorama.

This package provides a framework for working with formal language grammars. The library was originally developed for educational purposes and therefore implements many textbook algorithms regarding the manipulation and interaction with formal grammars.

The verboselogs package extends Python's logging module to add the log levels NOTICE, SPAM, SUCCESS and VERBOSE.

This package provides declarative command-line interfaces using argparse and dataclasses.

This package provides a Python progressbar library to provide visual (yet text based) progress to long running operations.

k5test is a library for setting up self-contained Kerberos 5 environments, and running Python unit tests inside those environments. It is based on the file of the same name found alongside the MIT Kerberos 5 unit tests.

This package provides a python port of YUI CSS Compressor.

This Python library makes it easy to display images and videos in a notebook.

The lockfile package exports a LockFile class which provides a simple API for locking files.

This is a plugin for the Python code checking tool Flake8 to encourage correct string literal concatenation.

It looks for style problems like implicitly concatenated string literals on the same line (which can be introduced by the code formatting tool Black), or unnecessary plus operators for explicit string literal concatenation.

This package provides a replacement for Python's subprocess feature.

This package provides python utilities to automatically color uncaught exception tracebacks.

PyRSS2Gen is the interface to generate RSS 2.0 feeds. PyRSS2Gen builds the feed up by using a XML generator.
