Straight Plugin provides a type of plugin you can create from almost any existing Python modules, and an easy way for outside developers to add functionality and customization to your projects with their own plugins.

Advanced Python Scheduler (APScheduler) is a Python library that lets you schedule your Python code to be executed later, either just once or periodically.

You can add new jobs or remove old ones on the fly as you please. If you store your jobs in a database, they will also survive scheduler restarts and maintain their state. When the scheduler is restarted, it will then run all the jobs it should have run while it was offline.

Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays are accelerated and use less memory than doing the same calculation in Python. In addition, its multi-threaded capabilities can make use of all your cores, which may accelerate computations, most specially if they are not memory-bounded (e.g. those using transcendental functions).

Netifaces is a Python module providing information on network interfaces in an easy and portable manner.

attrs is a Python package with class decorators that ease the chores of implementing the most common attribute-related object protocols.

This package provides a Flake8 lint for quotes.

Factory_boy is a fixtures replacement based on thoughtbot’s factory_girl. As a fixtures replacement tool, it aims to replace static, hard to maintain fixtures with easy-to-use factories for complex object. Instead of building an exhaustive test setup with every possible combination of corner cases, factory_boy allows you to use objects customized for the current test, while only declaring the test-specific fields.

The Munkres module provides an implementation of the Munkres algorithm (also called the Hungarian algorithm or the Kuhn-Munkres algorithm), useful for solving the Assignment Problem.

Parso is a Python parser that supports error recovery and round-trip parsing for different Python versions (in multiple Python versions). Parso is also able to list multiple syntax errors in your Python file.

ofxparse is a parser for Open Financial Exchange (.ofx) format files. OFX files are available from almost any online banking site, so they work well if you want to pull together your finances from multiple sources. Online trading accounts also often provide account statements in OFX files.

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.

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.

This software allows you to verify wheel filenames and parse them into their component fields.

This package adheres strictly to the standard, with the following exceptions:

• Version components may be any sequence of the relevant set of characters; they are not verified for PEP 440 compliance.

• The .whl file extension is matched case-insensitively.

This package cleans Jupyter notebooks of cell execution counts, metadata, outputs, and empty cells, preparing them for committing to version control. It provides a Git filter to automatically clean notebooks before they're staged, and can also be used with other version control systems, as a command line tool, and as a Python library.

Pure Python multicast DNS (mDNS) service discovery library (Bonjour/Avahi compatible).

Calmjs-parse is a collection of helper libraries for understanding ECMA script.

Sign JSON objects with ED25519 signatures.

• More than one entity can sign the same object.

• Each entity can sign the object with more than one key making it easier to rotate keys

• ED25519 can be replaced with a different algorithm.

• Unprotected data can be added to the object under the "unsigned" key.

This package provides JSON support files from the JSON Schema Specifications (metaschemas, vocabularies, etc.), packaged for runtime access from Python as a referencing-based Schema Registry.

python-aiofiles is a library for handling local disk files in asyncio applications.

This package provides a decorator that raises an error when an operation takes longer than expected.

The ld package provides information about the GNU/Linux distribution it runs on, such as a reliable machine-readable ID, or version information.

Pelican is a tool to generate a static blog from reStructuredText, Markdown input files, and more. Pelican uses Jinja2 for templating and is very extensible.

Pdftotext is a Python library of PDF text extraction.

This package provides a library for W3C Provenance Data Model supporting PROV-O (RDF), PROV-XML, PROV-JSON import/export.
