This package provides a decorator to create lazy attributes.

This package provides a Python library for http://semver.org/.

This package provides a Python library for working with and comparing language codes.

python-langcodes implements BCP 47, the IETF Best Current Practices on Tags for Identifying Languages. BCP 47 is also known as RFC 5646. It subsumes ISO 639 and is backward compatible with it, and it also implements recommendations from the Unicode CLDR.

python-langcodes can also refer to a database of language properties and names, built from Unicode CLDR and the IANA subtag registry, if you install python-language-data.

Invoke is a Python task execution tool and library, drawing inspiration from various sources to arrive at a powerful and clean feature set. It is evolved from the Fabric project, but focuses on local and abstract concerns instead of servers and network commands.

This regular expression implementation is backwards-compatible with the standard re module, but offers additional functionality like full case-folding for case-insensitive matches in Unicode.

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.

This package provides a Python parser for Pubmed Open-Access Subset and MEDLINE XML repository.

The minifier is based on the semantics of the YUI compressor, which itself is based on the rule list by Isaac Schlueter.

This package provides a read-only implementation of fsspec for IPFS.

This package provides a build backend that patches Poetry Core to enable the versioning system in PEP 517 build frontends.

Pexpect is a pure Python module for spawning child applications; controlling them; and responding to expected patterns in their output. Pexpect works like Don Libes’ Expect. Pexpect allows your script to spawn a child application and control it as if a human were typing commands.

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

This package provides JSON support files from the JSON Schema Specifications (metaschemas, vocabularies, etc.), packaged for runtime access from Python as a referencing-based Schema Registry.

Factory_boy is a fixtures replacement based on thoughtbot’s factory_girl. As a fixtures replacement tool, it aims to replace static, hard to maintain fixtures with easy-to-use factories for complex object. Instead of building an exhaustive test setup with every possible combination of corner cases, factory_boy allows you to use objects customized for the current test, while only declaring the test-specific fields.

Sphinx extension to support docstrings in Numpy format.

This package lets you parse Python docstrings in reST, Google and Numpydoc format.

This package provides a theme plugin for the static site generator MkDocs.

Boltons is a set of over 230 pure-Python utilities in the same spirit as — and yet conspicuously missing from — the standard library, including:

• Atomic file saving, bolted on with fileutils

• A highly-optimized OrderedMultiDict, in dictutils

• Two types of PriorityQueue, in queueutils

• Chunked and windowed iteration, in iterutils

• Recursive data structure iteration and merging, with iterutils.remap

• Exponential backoff functionality, including jitter, through iterutils.backoff

• A full-featured TracebackInfo type, for representing stack traces, in tbutils

Cloup enriches Click with several features that make it more expressive and configurable such as option groups, constraints, subcommand aliases, subcommands sections and a themeable HelpFormatter.

Markupsafe provides an XML/HTML/XHTML markup safe string implementation for Python.

Library for atomic file writes using platform dependent tools for atomic file system operations.

This package provides a YAML template engine with Python expressions.

olefile can parse, read and write Microsoft OLE2 files (Structured Storage or Compound Document, Microsoft Office). It is an improved version of the OleFileIO module from PIL, the Python Image Library.

Pabot is a parallel executor for Robot Framework tests.
