Param is a library for handling all the user-modifiable parameters, arguments, and attributes that control your code. It provides automatic, robust error-checking while dramatically reducing boilerplate code, letting you focus on what you want your code to do rather than on checking for all the possible ways users could supply inappropriate values to a function or class.

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.

Lexer and codec to work with LaTeX code in Python.

This is a Python library for computing common heuristic accuracy scores for various music/audio information retrieval/signal processing tasks.

eliot is a Python logging system that outputs causal chains of actions: actions can spawn other actions, and eventually they either succeed or fail. The resulting logs tell you the story of what your software did: what happened, and what caused it.

python-pymonad implements data structures typically available in purely functional or functional first programming languages such as Haskell and F#. Included are

• Monad and Monoid data types with several common monads such as Maybe and State

• Useful tools such as the @curry decorator for defining curried functions

• Type annotations to help ensure correct usage

Bitstring is a library for simple construction, analysis and modification of binary data.

Lazy object proxy is an object that wraps a callable but defers the call until the object is actually required, and caches the result of said call.

This Python module provides an abstraction layer for interacting with constraint solvers. Specifically, it is intended to be used with SMT solvers and is built on top of the Z3 solver.

OmegaConf is a hierarchical configuration system and supports merging configurations from multiple sources. It provides a consistent API regardless of how the configuration was created.

This library helps you read text from an unknown charset encoding. Motivated by chardet, it tries to resolve the issue by taking a new approach. All IANA character set names for which the Python core library provides codecs are supported.

pycodestyle (formerly pep8) is a tool to check Python code against some of the style conventions in PEP 8.

This is a Python port of markdown-it, and some of its associated plugins. The driving design philosophy of the port has been to change as little of the fundamental code structure (file names, function name, etc) as possible.

An immutable mapping type for Python. The underlying datastructure is a Hash Array Mapped Trie (HAMT) used in Clojure, Scala, Haskell, and other functional languages.

Macaroons, like cookies, are a form of bearer credential. Unlike opaque tokens, macaroons embed caveats that define specific authorization requirements for the target service, the service that issued the root macaroon and which is capable of verifying the integrity of macaroons it receives.

Macaroons allow for delegation and attenuation of authorization. They are simple and fast to verify, and decouple authorization policy from the enforcement of that policy.

PySAML2 is a pure python implementation of SAML Version 2 Standard. It contains all necessary pieces for building a SAML2 service provider or an identity provider. The distribution contains examples of both.

This package was originally written to work in a WSGI environment, but there are extensions that allow you to use it with other frameworks.

Python package can include a MANIFEST.in file to help with sending package files to the Python Package Index. This package checks that file to ensure it completely and accurately describes your project.

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.

Feedgenerator-py3k is a standalone version of Django's feedgenerator, which can produce feeds in RSS 2.0, RSS 0.91, and Atom formats.

Retrying is a general-purpose retrying library to simplify the task of adding retry behavior to just about anything.

Features:

• Generic Decorator API.

• Specify stop condition (i.e. limit by number of attempts).

• Specify wait condition (i.e. exponential backoff sleeping between attempts).

• Customize retrying on Exceptions.

• Customize retrying on expected returned result.

filelock contains a single module implementing a platform independent file lock in Python, which provides a simple way of inter-process communication.

Pabot is a parallel executor for Robot Framework tests.

This Python library provides interfaces for parsing and analyzing two binary and library file formats ; the Executable and Linking Format (ELF), and debugging information in the Debugging With Attributed Record Format (DWARF).

Lark is a parser built with a focus on ergonomics, performance and resilience. Lark can parse all context-free languages. That means it is capable of parsing almost any programming language out there, and to some degree most natural languages too.
