easyprocess is an easy to use Python subprocess interface.

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

Six is a Python 2 and 3 compatibility library. It provides utility functions for smoothing over the differences between the Python versions with the goal of writing Python code that is compatible on both Python versions. Six supports every Python version since 2.5. It is contained in only one Python file, so it can be easily copied into your project.

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

Pygit2 is a set of Python bindings to the libgit2 shared library.

language_data is a supplement to the langcodes module, for working with standardized codes for human languages. It stores the more bulky and hard-to-index data about languages, particularly what they are named in various languages.

The uncertainties package transparently handles calculations with numbers with uncertainties. It can also yield the derivatives of any expression.

This package provides python utilities to automatically color uncaught exception tracebacks.

This module provides a Python interface to pkg-config. It can be used to find all pkg-config packages, check if a package exists, check if a package meets certain version requirements, query CFLAGS and LDFLAGS and parse the output to build extensions with setup.py.

This package provides tools to convert files in the format used by multiple Spanish banks (standard 43 of the Spanish Banking Council [CSB43] / Spanish Banking Association [AEB43]) to other formats.

Python-Titlecase is a Python port of John Gruber's titlecase.pl. It capitalizes (predominantly English) strings in a way that is similar to book titles, using the New York Times Manual of Style to leave certain words lowercase.

Panflute is a Python package that makes Pandoc filters fun to write. It is a pythonic alternative to John MacFarlane's pandocfilters, from which it is heavily inspired.

Celery is an asynchronous task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well. The execution units, called tasks, are executed concurrently on a single or more worker servers using multiprocessing, Eventlet, or gevent. Tasks can execute asynchronously (in the background) or synchronously (wait until ready).

NLTK provides interfaces to over 50 corpora and lexical resources such as WordNet, along with a suite of text processing libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning, wrappers for natural language processing libraries.

The fastbencode Python package implements the bencode serialization format for storing and transmitting loosely structured data, originally used by BitTorrent.

The format can encode four different types of values: byte strings, integers, lists, and dictionaries (associative arrays). It's simple and unaffected by endianness,

This package includes both a pure-Python version and an optional C extension based on Cython. Both provide the same functionality, but the C version has significantly better performance.

userspacefs is a library that allows you to easily write user-space file systems in Python.
