This package provides ASN.1 parsing, encoding and decoding for Python, including constraints checking. It supports several codecs (e.g. BER, PER, UPER, XER) as well as limited C source code generating for OER and UPER.

pyvirtualdisplay is a Python wrapper for Xvfb, Xephyr and Xvnc.

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.

Babel is composed of two major parts: - tools to build and work with gettext message catalogs - a Python interface to the CLDR (Common Locale Data Repository), providing access to various locale display names, localized number and date formatting, etc.

SQLGlot is a no-dependency SQL parser, transpiler, optimizer, and engine. It can be used to format SQL or translate between 31 different dialects like DuckDB, Presto / Trino, Spark / Databricks, Snowflake, and BigQuery. It aims to read a wide variety of SQL inputs and output syntactically and semantically correct SQL in the targeted dialects.

Ice is a comprehensive RPC framework. Ice helps you network your software by taking care of all interactions with low-level network programming interfaces.

This package provides an object type which efficiently represents an array of booleans. Bitarrays are sequence types and behave very much like usual lists. Eight bits are represented by one byte in a contiguous block of memory. The user can select between two representations: little-endian and big-endian. All of the functionality is implemented in C. Methods for accessing the machine representation are provided. This can be useful when bit level access to binary files is required, such as portable bitmap image files. Also, when dealing with compressed data which uses variable bit length encoding, you may find this module useful.

A Python wrapper for the dialog utility. Its purpose is to provide an easy to use, pythonic and comprehensive Python interface to dialog. This allows one to make simple text-mode user interfaces on Unix-like systems

typogrify provides a set of custom filters that automatically apply various transformations to plain text in order to yield typographically-improved HTML. While often used in conjunction with Jinja and Django template systems, the filters can be used in any environment.

Incremental is a small library that versions your Python projects.

IPython provides a rich architecture for interactive computing with: Powerful interactive shells, a browser-based notebook, support for interactive data visualization, embeddable interpreters and tools for parallel computing.

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.

Grandalf is a Python package made for experimentations with graphs drawing algorithms. It is written in pure Python, and currently implements two layouts: the Sugiyama hierarchical layout and the force-driven or energy minimization approach. While not as fast or featured as graphviz or other libraries like OGDF (C++), it provides a way to walk and draw graphs no larger than thousands of nodes, while keeping the source code simple enough to tweak and hack any part of it for experimental purpose. With a total of about 1500 lines of Python, the code involved in drawing the Sugiyama (dot) layout fits in less than 600 lines. The energy minimization approach is comprised of only 250 lines!

Grandalf does only 2 not-so-simple things:

• computing the nodes (x,y) coordinates (based on provided nodes dimensions, and a chosen layout)

• routing the edges with lines or nurbs

It doesn’t depend on any GTK/Qt/whatever graphics toolkit. This means that it will help you find where to draw things like nodes and edges, but it’s up to you to actually draw things with your favorite toolkit.

Python MPV JSONIPC implements an interface similar to python-mpv, but it uses the JSON IPC protocol instead of the C API.

easyprocess is an easy to use Python subprocess interface.

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 package provides a python client for the Valkey key-value store, forked from redis-py.

This Python library provides context managers-related procedures.

This tool lets you debug variables, expressions, and program execution with one function call. IceCream makes print debugging a little sweeter.

Wrappers to build Python packages using PEP 517 hooks.

Bagit is a Python library and command line utility for working with BagIt style packages. BagIt is a minimalist packaging format for digital preservation.

This package provides Python bindings to libdbus, the reference implementation of the D-Bus protocol.

tablib is a format-agnostic tabular dataset library, written in Python. Supported output formats are Excel (Sets + Books), JSON (Sets + Books), YAML (Sets + Books), HTML (Sets), Jira (Sets), TSV (Sets), ODS (Sets), CSV (Sets), and DBF (Sets).

tablib also supports Pandas DataFrames (Sets). Anyhow, since pandas is quite huge, this Guix package doesn't depend on pandas. In case, just also install python-pandas.

This package contains a small collection of test tool plugins for nose2 and flake8.
