Yapsy, or Yet Another Plugin SYstem, is a small library implementing the core mechanisms needed to build a plugin system into a wider application.

The main purpose is to depend only on Python's standard libraries and to implement only the basic functionalities needed to detect, load and keep track of several plugins.

Grandalf is a Python package made for experimentations with graphs drawing algorithms. It is written in pure Python, and currently implements two layouts: the Sugiyama hierarchical layout and the force-driven or energy minimization approach. While not as fast or featured as graphviz or other libraries like OGDF (C++), it provides a way to walk and draw graphs no larger than thousands of nodes, while keeping the source code simple enough to tweak and hack any part of it for experimental purpose. With a total of about 1500 lines of Python, the code involved in drawing the Sugiyama (dot) layout fits in less than 600 lines. The energy minimization approach is comprised of only 250 lines!

Grandalf does only 2 not-so-simple things:

• computing the nodes (x,y) coordinates (based on provided nodes dimensions, and a chosen layout)

• routing the edges with lines or nurbs

It doesn’t depend on any GTK/Qt/whatever graphics toolkit. This means that it will help you find where to draw things like nodes and edges, but it’s up to you to actually draw things with your favorite toolkit.

This library provides Python functions that wraps the Kerberos 5 C API.

FontTools/TTX is a library to manipulate font files from Python. It supports reading and writing of TrueType/OpenType fonts, reading and writing of AFM files, reading (and partially writing) of PS Type 1 fonts. The package also contains a tool called “TTX” which converts TrueType/OpenType fonts to and from an XML-based format.

EasyGUI is a module for easy GUI programming in Python. EasyGUI is different from other GUI generators in that EasyGUI is NOT event-driven. Instead, all GUI interactions are invoked by simple function calls.

python-osc is a pure Python library with no external dependencies. It implements the Open Sound Control 1.0 specification.

SeleniumLibrary is a web testing library for Robot Framework that utilizes the Selenium tool internally.

This Python library implements 3-way merge for text.

This module implements the password-based key derivation function, PBKDF2, specified in RSA PKCS#5 v2.0.

PKCS#5 v2.0 Password-Based Key Derivation is a key derivation function which is part of the RSA Public Key Cryptography Standards series. The provided implementation takes a password or a passphrase and a salt value (and optionally a iteration count, a digest module, and a MAC module) and provides a file-like object from which an arbitrarily-sized key can be read.

Orderly Set is a package containing multiple implementations of Ordered Set.

cliapp is a Python framework for command line programs. It contains the typical stuff such programs need to do, such as parsing the command line for options, and iterating over input files.

This package provides a versatile binary analysis platform with the ability to perform dynamic symbolic execution as well as various static analyses directly on binaries. As such, it can be used for all kinds of reverse engineering, vulnerability discovery, exploit generation, and software testing purposes.

This package implements an installer for Python Build Standalone.

This package provides an implementation of generic floating point encode and decode logic in Python. It handles various current and proposed floating point types:

• IEEE 754: Binary16, Binary32

• OCP Float8: E5M2, E4M3

• IEEE WG P3109

• OCP MX Formats: E2M1, M2M3, E3M2, E8M0, INT8, and the MX block formats.

This is a PEP 561 type stub package for the python-dateutil package.

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

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.

mpmath can be used as an arbitrary-precision substitute for Python's float/complex types and math/cmath modules, but also does much more advanced mathematics.

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.

This Python package provides progress reporting for visual of progress of long running operations. There are multiple choices of progress bars and spinners, with customizable options, such as width, fill character, and suffix.

Typing stubs for simplejson.

This package provides bindings for wcwidth and wcswidth functions defined in POSIX.1-2001 and POSIX.1-2008.

textdistance is a pure Python library for comparing distance between two or more sequences by many algorithms.

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