flex can be used to validate Swagger schemata.

This package provides a port of the serialize and unserialize functions of PHP for Python.

GraphQL implementation for Python. GraphQL is a data query language and runtime designed and used to request and deliver data to mobile and web apps. This library is a port of graphql-js to Python.

This library provides functionality to decompile AST objects, as generated by the standard library ast module, to Python code.

This Python library allows communicating with the U3, U6, UE9 and U12 LabJack data acquisition (DAQ) modules.

This package contains operations on PyTrees (a tree made of container data structures in Python).

This package provides a Python library to create SVG drawings.

Cron-converter provides a Cron string parser (from string/lists to string/lists) and iteration for the datetime object with a cron like format.

This package provides a standalone variant of distutils.version and packaging.version, without anything else.

Pynotify2 provides a Python interface for sending D-Bus notifications. It is a reimplementation of pynotify in pure Python, and an alternative to the GObject Introspection bindings to libnotify for non-GTK applications.

Avoid repetitive boilerplate code in Python classes.

Importmagic is a Python library for automatically managing imports by finding unresolved symbols in Python code and their corresponding imports.

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.

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.

This package provides efficient Python bindings to picosat on the C level. When importing pycosat, the picosat solver becomes part of the Python process itself. picosat is a Boolean Satisfiability Problem (SAT) solver.

This package lets you run asynchronous workflows using pytest-fixtures-style dependency injection.

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.

Lmfit provides a high-level interface to non-linear optimization and curve fitting problems for Python. It builds on and extends many of the optimization methods of scipy.optimize. Initially inspired by (and named for) extending the Levenberg-Marquardt method from scipy.optimize.leastsq, lmfit now provides a number of useful enhancements to optimization and data fitting problems.

This package provides a lightweight YAML Parser for Python. It supports only a chosen subset of the YAML format that is required to parse cookiecutter user configuration files. It does not have support for serializing into YAML and is not compatible with JSON.

This package provides a module for generating v4 UUIDs and encoding them into 22 character URL-safe base64 slug representation.

Fire is a library for automatically generating command line interfaces from absolutely any Python object. The following are the advantages:

• A simple way to create a CLI in Python.

• A helpful tool for developing and debugging Python code.

• Helps with exploring existing code or turning other people's code into a command line interface.

• Makes transitioning between Bash and Python easier.

• Makes using a Python REPL easier by setting up the REPL with the modules and variables you'll need already imported and created.

This package provides a standard for generating test points and exchanging variables, objectives, and constraints in optimization problems.

It is an effort to standardize the interface of the generators in optimization libraries such as:

• Xopt - flexible high-level optimization in Python

• optimas - optimization at scale, powered by libEnsemble

• libEnsemble - a Python toolkit for coordinating asynchronous and dynamic ensembles of calculations

• rsopt - flexible configuration and execution of large, black-box optimization problems

This project documents instruction sets in a format convenient for tools development. An instruction set is represented by three files:

• an XML file that describes instructions;

• an XSD file that describes the structure of the XML file;

• a Python module that reads the XML file and represents it as a set of Python objects;

It currently provides descriptions for most user-mode x86, x86_64, and k1om instructions up to AVX-512 and SHA (including 3dnow!+, XOP, FMA3, FMA4, TBM and BMI2).

Wadler-Lindig is a minimal, zero-dependency pretty-printing library for Python that implements a simplified version of the Wadler-Lindig algorithm. Designed to consume less horizontal space than Python's built-in pprint.pprint, it produces compact, well-formatted representations even for complex custom types.
