Voluptuous is a Python data validation library. It is primarily intended for validating data coming into Python as JSON, YAML, etc.

This library extends the standard functools Python module with a few extra procedures.

This package allows to detect if the user is using Dark Mode.

FontTools/TTX is a library to manipulate font files from Python. It supports reading and writing of TrueType/OpenType fonts, reading and writing of AFM files, reading (and partially writing) of PS Type 1 fonts. The package also contains a tool called “TTX” which converts TrueType/OpenType fonts to and from an XML-based format.

makefun helps create functions dynamically with a given signature. It was largely inspired by python-decorator and functools.

This package contains a plugin that provides specializations for type hinting stub files, especially interesting for linting typeshed. It adds the .pyi extension to the default value of the --filename command-line argument to Flake8. This means stubs are linted by default with this plugin enabled, without needing to explicitly list every file. It modifies PyFlakes runs for .pyi files to defer checking type annotation expressions after the entire file has been read. This enables support for first-class forward references that stub files use.

This package implements a functionality to access of environment variables from Python with support for strings, booleans, list, tuples, and dicts.

This package provides POSIX IPC primitives - semaphores, shared memory and message queues for Python.

The Levenshtein Python C extension module contains functions for fast computation of

1. Levenshtein (edit) distance, and edit operations

2. string similarity

3. approximate median strings, and generally string averaging

4. string sequence and set similarity

It supports both normal and Unicode strings.

Deterministically encode JSON.

• Encodes objects and arrays as RFC 7159 JSON.

• Sorts object keys so that you get the same result each time.

• Has no insignificant whitespace to make the output as small as possible.

• Escapes only the characters that must be escaped, U+0000 to U+0019 / U+0022 / U+0056, to keep the output as small as possible.

• Uses the shortest escape sequence for each escaped character.

• Encodes the JSON as UTF-8.

• Can encode frozendict immutable dictionaries.

This package provides the rnc2rng command-line tool as well as a Python library to convert RELAX NG schemata in Compact syntax (rnc) to equivalent schemata in the XML-based default RELAX NG syntax.

This package provides a simple async process supervisor in Python.

The goal of this project is to manage configuration for Python tools, such as rope and add support for a pyproject.toml configuration file.

This package provides support for the APA style within pybtex.

This package implements a functionality to deal with RabbitMQ Streams using asyncio.

It is designed and implemented with the following qualities in mind:

• asynchronous Pythonic API with type annotations

• use of AMQP 1.0 message format to enable interoperability between RabbitMQ Stream. clients

• auto reconnection to RabbitMQ broker with lazily created connection objects

Support of many RabbitMQ Streams broker features:

• publishing single messages, or in batches, with confirmation

• subscribing to a stream at a specific point in time, from a specific offset, or using offset reference

• stream message filtering

• writing stream offset reference

• message deduplication

• integration with AMQP 1.0 ecosystem at message format level

This package enables Python programs to dynamically access arbitrary Java objects.

oj is a command line tool to help solving problems on various online judges. This command automates downloading sample cases, generating additional test cases, testing for your code, and submitting it.

This package provides tools to build manual pages from Python's ArgumentParser object.

Databind is a library inspired by jackson-databind to de-/serialize Python dataclasses.

Python SDK for reporting exceptions, errors, and log messages to Rollbar.

Capabilities include:

• Sending messages and exceptions with arbitrary context

• Getting back aggregates

• Debugging production issues

This package provides a Python library intended to make color math, color scales, and color space conversion easy. It has support for:

1. Color scales

2. Color ranges

3. Color blending

4. Brightening/darkening colors

5. Saturating/desaturating colors

6. Conversion to/from multiple color spaces.

Boltons is a set of over 230 pure-Python utilities in the same spirit as — and yet conspicuously missing from — the standard library, including:

• Atomic file saving, bolted on with fileutils

• A highly-optimized OrderedMultiDict, in dictutils

• Two types of PriorityQueue, in queueutils

• Chunked and windowed iteration, in iterutils

• Recursive data structure iteration and merging, with iterutils.remap

• Exponential backoff functionality, including jitter, through iterutils.backoff

• A full-featured TracebackInfo type, for representing stack traces, in tbutils

The scp module extends the Paramiko library to send and receive files via the SCP1 protocol, as implemented by the OpenSSH scp program.

This package provides a parser to parse binary structs into dataclasses.
