Orjson is a fast, correct JSON library for Python. It benchmarks as the fastest Python library for JSON and is more correct than the standard json library or other third-party libraries. It serializes dataclass, datetime, numpy, and UUID instances natively.

This package provides a library to choose unique available network ports.

The library helps you to store logs in JSON format.

Grako takes a grammar in a variation of EBNF as input, and outputs a memoizing PEG/Packrat parser in Python.

Halo is a Python library to display graphical spinners in the terminal. It also supports IPython/Jupyter.

The PyPNG module implements support for PNG images. It reads and writes PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 bits per pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, RGBA, LA (greyscale with alpha) with 8/16 bits per channel; colour mapped images (1/2/4/8 bit). Adam7 interlacing is supported for reading and writing. A number of optional chunks can be specified (when writing) and understood (when reading): tRNS, bKGD, gAMA.

PyPNG is not a high level toolkit for image processing (like PIL) and does not aim at being a replacement or competitor. Its strength lies in fine-grained extensive support of PNG features. It can also read and write Netpbm PAM files, with a focus on its use as an intermediate format for implementing custom PNG processing.

Logbook is a logging system for Python that replaces the standard library’s logging module. It was designed with both complex and simple applications in mind and the idea to make logging fun.

This module provides a Python version of node-semver, a semantic version parser for Node.js.

PyMD4C provides Python bindings for MD4c, a C Markdown parser, compliant to CommonMark.

Unidecode provides ASCII transliterations of Unicode text. Unidecode is useful when integrating with legacy code that doesn't support Unicode, or for ease of entry of non-Roman names on a US keyboard, or when constructing ASCII machine identifiers from human-readable Unicode strings that should still be somewhat intelligible.

This package provides a functionality for working with user perceived characters. More specifically, string manipulation and calculation functions for working with grapheme cluster groups (graphemes) as defined by the Unicode Standard Annex #29.

shortuuid is a Python library for generating concise, unambiguous and URL-safe UUIDs. UUIDs are generated using the built-in Python uuid module and then similar looking characters are removed.

Python one-time password library for HMAC-based (HOTP) and time-based (TOTP) passwords.

GAST provides a compatibility layer between the AST of various Python versions, as produced by ast.parse from the standard ast module.

The jupyter_client package contains the reference implementation of the Jupyter protocol. It also provides client and kernel management APIs for working with kernels, and the jupyter kernelspec entrypoint for installing kernelspecs for use with Jupyter frontends.

Universal Pathlib is a Python library that extends the pathlib.Path API to support a variety of backend filesystems via filesystem_spec.

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.

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.

This package provides universal classes and methods for the Iron.io API wrappers to build on.

The capturer package makes it easy to capture the stdout and stderr streams of the current process and subprocesses. Output can be relayed to the terminal in real time but is also available to the Python program for additional processing.

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

This package provides an extension for the template engine Jinja2. It adds a 'now' tag providing a convenient access to the arrow.now() API from templates. A format string can be provided to control the output.

Huey is a lightweight task queue for Python applications. Huey supports:

• Redis, SQLite, file-system, or in-memory storage

• multi-process, multi-thread or greenlet task execution models

• scheduling tasks to execute at a given time, or after a given delay

• scheduling recurring tasks, like a crontab

• automatically retrying tasks that fail

• task prioritization

• task result storage

• task expiration

• task locking

• task pipelines and chains
