This package provides a quick single file library for easily adding evaluatable expressions into python projects. Say you want to allow a user to set an alarm volume, which could depend on the time of day, alarm level, how many previous alarms had gone off, and if there is music playing at the time.

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

The fastbencode Python package implements the bencode serialization format for storing and transmitting loosely structured data, originally used by BitTorrent.

The format can encode four different types of values: byte strings, integers, lists, and dictionaries (associative arrays). It's simple and unaffected by endianness,

This package includes both a pure-Python version and an optional C extension based on Cython. Both provide the same functionality, but the C version has significantly better performance.

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.

Piexif simplifies interacting with EXIF data in Python. It includes the tools necessary for extracting, creating, manipulating, converting and writing EXIF data to JPEG, WebP and TIFF files.

The ResolveLib library provides a Resolver class that includes dependency resolution logic.

Archspec offers human-readable labels for system architecture aspects. These aspects include CPU, network fabrics, etc. In addition, it offers APIs to detect, query, and compare them.

structlog changes logging in Python by adding structure to your log entries.

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.

python-schema is a library for validating Python data structures, such as those obtained from config-files, forms, external services or command-line parsing, converted from JSON/YAML (or something else) to Python data-types.

vine provides a special implementation of promises in that it can be used both for "promise of a value" and lazy evaluation. The biggest upside for this is that everything in a promise can also be a promise, e.g. filters, callbacks and errbacks can all be promises.

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.

Pydoc-Markdown is a tool to create Python API documentation in Markdown format. Instead of executing your Python code like so many other documentation tools, it parses it using docspec instead.

This package provides a Python wrapper for using extended file system attributes. Extended attributes extend the basic attributes of files and directories in the file system. They are stored as name:data pairs associated with file system objects (files, directories, symlinks, etc).

This project does not implement the parsing of pyproject.toml containing PEP 621 metadata. Instead, given a Python data structure representing PEP 621 metadata (already parsed), it will validate this input and generate a PEP 643-compliant metadata file (e.g. PKG-INFO).

This package provides a library for communicating with the GA4GH Task Execution API.

MessagePack is a fast, compact binary serialization format, suitable for similar data to JSON. This package provides CPython bindings for reading and writing MessagePack data.

This package provides time-handling functionality that used to be part of the netcdf4 package before.

This package provides a text progress bar library for Python. This version only differs from the original progressbar package in that it uses relative package imports instead of absolute imports, which is necessary for the module to work under Python 3.3.

This Python package provides buffer compression and transformation codecs for use in data storage and communication applications.

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

Retrying is a general-purpose retrying library to simplify the task of adding retry behavior to just about anything.

Features:

• Generic Decorator API.

• Specify stop condition (i.e. limit by number of attempts).

• Specify wait condition (i.e. exponential backoff sleeping between attempts).

• Customize retrying on Exceptions.

• Customize retrying on expected returned result.

This package provides Python module to slice a list of sliceables (1 indexed, both start and end index are inclusive). Helps to slice file content line by line or column by column or a combination of both.

Wcwidth measures the number of terminal column cells of wide-character codes. It is useful for those implementing a terminal emulator, or programs that carefully produce output to be interpreted by one. It is a Python implementation of the wcwidth and wcswidth C functions specified in POSIX.1-2001 and POSIX.1-2008.
