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.

Pretend is a library to make stubbing with Python easier. Stubbing is a technique for writing tests. You may hear the term mixed up with mocks, fakes, or doubles. Basically, a stub is an object that returns pre-canned responses, rather than doing any computation.

Pythran is an ahead of time compiler for a subset of the Python language, with a focus on scientific computing. It takes a Python module annotated with a few interface descriptions and turns it into a native Python module with the same interface, but (hopefully) faster.

bashlex is a Python port of the parser used internally by GNU bash.

For the most part it's transliterated from C, the major differences are:

• it does not execute anything

• it is reentrant

• it generates a complete AST

kitchen module provides a python API for all sorts of little useful snippets of code that everybody ends up writing for their projects but never seem big enough to build an independent release. Use kitchen and stop cutting and pasting that code over and over.

Dunamai is Python library and command line tool for producing dynamic, standards-compliant version strings, derived from tags in your version control system. This facilitates uniquely identifying nightly or per-commit builds in continuous integration and releasing new versions of your software simply by creating a tag.

Bz2file is a Python library for reading and writing bzip2-compressed files. It contains a drop-in replacement for the I/O interface in the standard library's bz2 module, including features from the latest development version of CPython that are not available in older releases.

This package provides thin Python bindings to compression and decomporession algorithms implemented in Rust. This allows for using algorithms such as Snappy without additional system dependencies. The following algorithms are available:

• Snappy

• Brotli

• Bzip2

• LZ4

• Gzip

• Deflate

• Zstd

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.

Pandas is a Python package providing fast, flexible, and expressive data structures designed to make working with structured (tabular, multidimensional, potentially heterogeneous) and time series data both easy and intuitive. It aims to be the fundamental high-level building block for doing practical, real world data analysis in Python.

Tzlocal returns a tzinfo object with the local timezone information. This module attempts to fix a glaring hole in pytz, that there is no way to get the local timezone information, unless you know the zoneinfo name, and under several distributions that's hard or impossible to figure out.

ogr2osm is a tool for converting ogr-readable files into OSM format. It supports reading from OGR files like shapefiles or PostgreSQL database and converts data into osm or osm.pbf formats. A translation file can be used to manipulate the data during conversion.

XGBoost is an optimized distributed gradient boosting library designed to be highly efficient, flexible and portable. It implements machine learning algorithms under the Gradient Boosting framework. XGBoost provides a parallel tree boosting (also known as GBDT, GBM) that solve many data science problems in a fast and accurate way.

extruct is a Python library for extracting embedded metadata from HTML markup. Currently, extruct supports:

• W3C's HTML Microdata

• embedded JSON-LD

• Microformat via mf2py

• Facebook's Open Graph

• (experimental) RDFa via rdflib

• Dublin Core Metadata (DC-HTML-2003)

This package provides a Python library intended to make color math, color scales, and color space conversion easy. It has support for:

1. Color scales

2. Color ranges

3. Color blending

4. Brightening/darkening colors

5. Saturating/desaturating colors

6. Conversion to/from multiple color spaces.

Parsley is a parsing library using PEG algorithm, so each expression in the grammar rules works like a Python expression. In particular, alternatives are evaluated in order, unlike table-driven parsers such as yacc, bison or PLY. Parsley is an implementation of OMeta, an object-oriented pattern-matching language.

Vobject is intended to be a full featured Python package for parsing and generating vCard and vCalendar files. Currently, iCalendar files are supported and well tested. vCard 3.0 files are supported, and all data should be imported, but only a few components are understood in a sophisticated way.

Tzlocal returns a tzinfo object with the local timezone information. This module attempts to fix a glaring hole in pytz, that there is no way to get the local timezone information, unless you know the zoneinfo name, and under several distributions that's hard or impossible to figure out.

Pyliblo is a Python wrapper for the liblo Open Sound Control (OSC) library. It supports almost the complete functionality of liblo, allowing you to send and receive OSC messages using a nice and simple Python API. Also included are the command line utilities send_osc and dump_osc.

Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.

aiohttp is an asynchronous HTTP client/server framework.

Its main features are:

• Supports both client and server side of HTTP protocol.

• Supports both client and server Web-Sockets out-of-the-box without the Callback Hell.

• Web-server has middlewares and pluggable routing.

Globber is a Python library for matching file names against glob patterns. In contrast to other glob-matching libraries, it matches arbitrary strings and doesn't require the matched names to be existing files. In addition, it supports the globstar ** operator to match an arbitrary number of path components.

Anndata is a package for simple (functional) high-level APIs for data analysis pipelines. In this context, it provides an efficient, scalable way of keeping track of data together with learned annotations and reduces the code overhead typically encountered when using a mostly object-oriented library such as scikit-learn.
