This package provides a data-structure parameterization system written for embedding context in JSON objects.

The deprecated decorator provides a convenient way to deprecate to deprecate classes, functions or methods.

This module defines a decorator to wrap legacy APIs. The primary use case is APIs defined before keyword-only parameters existed.

Python Utils is a collection of small Python functions and classes which make common patterns shorter and easier.

With apipkg you can control the exported namespace of a Python package and greatly reduce the number of imports for your users. It is a small pure Python module that works on virtually all Python versions.

This package implements functionality of RGB/CIE1931 'xy' gammuts conversion: Gamut A, B, and C.

The pure_eval Python library can safely evaluate abstract syntax tree (AST) nodes without side effects.

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.

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

Clint is a Python module filled with a set of tools for developing command-line applications, including tools for colored and indented output, progress bar display, and pipes.

Schematics is a Python library to combine types into structures, validate them, and transform the shapes of your data based on simple descriptions.

The internals are similar to ORM type systems, but there is no database layer in Schematics. Instead, building a database layer is easily made when Schematics handles everything except for writing the query. Schematics can be used for tasks where having a database involved is unusual.

This Python module defines a tiny language to evaluate and compare license expressions using boolean logic. Logical combinations of licenses can be tested for equality, containment, and equivalence. They can be normalised and simplified. It supports SPDX license expressions as well as other naming conventions and aliases in the same expression.

Retrieve a scale based on a given mode and starting note. Information about these scales can be found on Wikipedia.

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 cytoolz package implements the same API as provided by toolz. The main differences are that cytoolz is faster and cytoolz offers a C API that is accessible to other projects developed in Cython.

PyYAML is a YAML parser and emitter for Python. PyYAML features a complete YAML 1.1 parser, Unicode support, pickle support, capable extension API, and sensible error messages. PyYAML supports standard YAML tags and provides Python-specific tags that represent an arbitrary Python object.

pykakasi is a Python Natural Language Processing NLP library to transliterate hiragana, katakana and kanji (Japanese text) into rōmaji (Latin/Roman alphabet). It can handle characters in NFC form.

Its algorithms are based on the kakasi library, which is written in C.

This package provides a YAML template engine with Python expressions.

Python bindings for ManimPango which is a C binding for Pango, using Cython.

ManimPango is internally used in Manim to render (non-LaTeX) text.

The isoweek module provide the class Week that implements the week definition of ISO 8601. This standard also defines a notation for identifying weeks; yyyyWww (where the W is a literal). Week instances stringify to this form.

This package provides a Doxygen input filter for QML files.

Argh is a small library that provides several layers of abstraction on top of python-argparse. The layers can be mixed. It is always possible to declare a command with the highest possible (and least flexible) layer and then tune the behaviour with any of the lower layers including the native API of python-argparse.

Roifile is a Python library to read, write, create, and plot ImageJ ROIs, an undocumented and ImageJ application specific format to store regions of interest, geometric shapes, paths, text, etc for image overlays.

rfc3986 is a Python implementation of RFC 3986 including validation and authority parsing. This module also supports RFC 6874 which adds support for zone identifiers to IPv6 addresses.
