Celery is an asynchronous task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well. The execution units, called tasks, are executed concurrently on a single or more worker servers using multiprocessing, Eventlet, or gevent. Tasks can execute asynchronously (in the background) or synchronously (wait until ready).

The stack_data Python library extracts data from stack frames and tracebacks. Is can be used to display more useful tracebacks than the default.

Munch is a dot-accessible dictionary similar to JavaScript objects.

pathvalidate is a Python library to sanitize/validate strings representing paths or filenames.

This tool lets you debug variables, expressions, and program execution with one function call. IceCream makes print debugging a little sweeter.

This Python library provides an ordered dictionary with a maximum capacity and auto-expiring values for caching purposes. Expiration happens on any access, object is locked during cleanup from expired values.

This package provides a tool for translation and localization of Python programs via modification of source files. Trubar supports f-strings and does not require any changes to the original source code, such as marking strings for translation.

This module provides utilities for multiplexing interactions with lists of Python objects.

Python package to work with Document Object Identifier (doi).

Twisted is an extensible framework for Python programming, with special focus on event-based network programming and multiprotocol integration.

Sorted Collections is a Python sorted collections library.

The mercantile module provides ul(xtile, ytile, zoom) and bounds(xtile, ytile, zoom) functions that respectively return the upper left corner and bounding longitudes and latitudes for XYZ tiles, a xy(lng, lat) function that returns spherical mercator x and y coordinates, a tile(lng, lat, zoom) function that returns the tile containing a given point, and quadkey conversion functions quadkey(xtile, ytile, zoom) and quadkey_to_tile(quadkey) for translating between quadkey and tile coordinates.

rustworkx is a Python package for working with graphs and complex networks. It enables the creation, interaction with, and study of graphs and networks.

pyTooling is a collection of (abstract) data models, lacking classes, decorators, a new performance boosting meta-class, and enhanced exceptions. It also provides lots of helper functions---e.g., to ease the handling of package descriptions or to unify multiple existing APIs into a single API.

This package provides an implementation-agnostic implementation of JSON reference resolution.

PyTables is a package for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data.

This package provides a spec-compliant gitignore parser for Python.

Tabulate is a library and command-line utility to pretty-print tabular data in Python.

This collection of utilities contains tooling and templates to assist in creating releases on GitHub and publishing them on PyPI. It is designed to be used by Robot Framework and tools and libraries in its ecosystem, but can naturally be used also by other projects.

Radon is a Python tool which computes various code metrics. Supported metrics are:

• raw metrics: SLOC, comment lines, blank lines, &c.

• Cyclomatic Complexity (i.e., McCabe’s Complexity)

• Halstead metrics (all of them)

• the Maintainability Index (a Visual Studio metric)

This package validates Internationalized Resource Identifiers (IRIs) and their components against the ABNF grammar from RFC 3987. Built on the Lark parser, it is an MIT-licensed alternative to the GPL-licensed rfc3987 package, and provides the format-nongpl extra required by recent jsonschema releases.

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.

This package provides a collection of miscellaneous utility functions and classes.

This package provides an implementation in Python using scipy and numpy of negative binomial maximum likelihood estimation.
