marshmallow provides a library for converting complex datatypes to and from native Python datatypes.

distro provides information about the OS distribution it runs on, such as a reliable machine-readable ID, or version information.

It is the recommended replacement for Python's original `platform.linux_distribution` function (which will be removed in Python 3.8). distro also provides a command-line interface to output the platform information in various formats.

This DBus library is written in Python, based on GLib and inspired by pydbus.

This package implements an installer for Python Build Standalone.

Sqltrie is a SQL-based prefix tree inspired by pygtrie and python-diskcache.

This package provides metadata objects which can be used to represent common constraints such as upper and lower bounds on scalar values and collection sizes, a Predicate marker for runtime checks, and descriptions of how we intend these metadata to be interpreted. In some cases, we also note alternative representations which do not require this package.

python-isbnlib is a (pure) python library that provides several useful methods and functions to validate, clean, transform, hyphenate and get metadata for ISBN strings. Its origin was as the core of isbntools. This short version, is suitable to be include as a dependency in other projects.

Cog is a file generation tool. It allows using pieces of Python code as generators in your source files to generate arbitrary text.

Human-friendly Hue Saturation Lightness. HSLuv extends CIELUV with a new saturation component that allows you to span all the available chroma as a neat percentage.

This Python module can read, write crontab files, and access the system cron automatically and simply using a direct API.

This package provides the complete NumPy documentation in the Texinfo, and HTML formats.

Cheetah is a text-based template engine and Python code generator.

Cheetah can be used as a standalone templating utility or referenced as a library from other Python applications. It has many potential uses, but web developers looking for a viable alternative to ASP, JSP, PHP and PSP are expected to be its principle user group.

Features:

1. Generates HTML, SGML, XML, SQL, Postscript, form email, LaTeX, or any other text-based format.

2. Cleanly separates content, graphic design, and program code.

3. Blends the power and flexibility of Python with a simple template language that non-programmers can understand.

4. Gives template writers full access to any Python data structure, module, function, object, or method in their templates.

5. Makes code reuse easy by providing an object-orientated interface to templates that is accessible from Python code or other Cheetah templates. One template can subclass another and selectively reimplement sections of it.

6. Provides a simple, yet powerful, caching mechanism that can dramatically improve the performance of a dynamic website.

7. Compiles templates into optimized, yet readable, Python code.

Flit is a simple way to put Python packages and modules on PyPI. Flit packages a single importable module or package at a time, using the import name as the name on PyPI. All subpackages and data files within a package are included automatically.

XlsxWriter is a Python module that can be used to write text, numbers, formulas and hyperlinks to multiple worksheets in an Excel 2007+ XLSX file.

This package provides a Doxygen input filter for QML files.

zipstream.py is a zip archive generator based on zipfile.py. It was created to generate a zip file generator for streaming. This is beneficial for when you want to provide a downloadable archive of a large collection of regular files, which would be infeasible to generate the archive prior to downloading or of a very large file that you do not want to store entirely on disk or on memory.

Kazoo is a Python client library for the Apache Zookeeper distributed application service. It is designed to be easy to use and to avoid common programming errors.

This library implements algorithms and data structures for Lisp-style cons cells in Python.

This package provides a wrapper around NumPy and other array libraries to make them compatible with the Array API standard

A library designed to represent tabular data in visually appealing ASCII tables. PrettyTable allows for selection of which columns are to be printed, independent alignment of columns (left or right justified or centred) and printing of sub-tables by specifying a row range.

This library provides Python functions that wraps the Kerberos 5 C API.

py010parser is a Python library for parsing templates for the Sweetscape 010 binary-format editor.

Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays are accelerated and use less memory than doing the same calculation in Python. In addition, its multi-threaded capabilities can make use of all your cores, which may accelerate computations, most specially if they are not memory-bounded (e.g. those using transcendental functions).

This library provides an efficient mechanism for overloading function implementations based on the types of the arguments.
