The ratelimiter module ensures that an operation will not be executed more than a given number of times during a given period.

This module provides two help formatters for optparse. They provide terser and more customizable option formatting in comparison to the default help formatter.

Poetry plugin to export the dependencies to various formats.

PeachPy is a Python framework for writing high-performance assembly kernels. PeachPy aims to simplify writing optimized assembly kernels while preserving all optimization opportunities of traditional assembly.

PeachPy can generate ELF, MS-COFF, Mach-O object files, and assembly listings for the Go language tool chain; it adapts to different calling conventions and application binary interfaces (ABIs); it takes care of register allocation; it supports x86_64 instructions up to AVX-512 and SHA.

This Python library implements 3-way merge for text.

python-pyre-extensions defines extensions to the standard typing module that are supported by the Pyre typechecker.

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.

Gamera is a toolkit for building document image recognition systems.

Confuse is a configuration library for Python that uses YAML. It takes care of defaults, overrides, type checking, command-line integration, human-readable errors, and standard OS-specific locations.

Pyphen is a pure Python module to hyphenate text using existing Hunspell hyphenation dictionaries.

The pysol-cards python modules provide code to generate the initial deals of some PySol games.

The PyPNG module implements support for PNG images. It reads and writes PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 bits per pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, RGBA, LA (greyscale with alpha) with 8/16 bits per channel; colour mapped images (1/2/4/8 bit). Adam7 interlacing is supported for reading and writing. A number of optional chunks can be specified (when writing) and understood (when reading): tRNS, bKGD, gAMA.

PyPNG is not a high level toolkit for image processing (like PIL) and does not aim at being a replacement or competitor. Its strength lies in fine-grained extensive support of PNG features. It can also read and write Netpbm PAM files, with a focus on its use as an intermediate format for implementing custom PNG processing.

Jellyfish uses a variety of string comparison and phonetic encoding algorithms to do fuzzy string matching.

This Python library can be used to create and update Microsoft Word (.docx) documents.

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.

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

This library provides a publish-subscribe API to facilitate event-based or message-based architecture in a single-process application. It is centered on the notion of a topic - senders publish messages of a given topic, and listeners subscribe to messages of a given topic, all inside the same process.

This library provides a Python module to parse command-line arguments.

MonthDelta provides functionality to do date computations with months.
