This package provides tools for interactive plots and applications in the browser from Python.

Babel is composed of two major parts: - tools to build and work with gettext message catalogs - a Python interface to the CLDR (Common Locale Data Repository), providing access to various locale display names, localized number and date formatting, etc.

Cython is an optimising static compiler for both the Python programming language and the extended Cython programming language. It makes writing C extensions for Python as easy as Python itself.

This package includes Controller Area Network (CAN) related tools that can be used to:

• parse DBC, KCD, SYM, ARXML 4 and CDD files

• encode and decode CAN messages

• multiplex simple and extended signals

• diagnose DID encoding and decoding

• dump the CAN decoder output

• test CAN nodes

• generate C source code

• monitor the CAN bus

PyTables is a package for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data.

The Python X Library is intended to be a fully functional X client library for Python programs. It is useful to implement low-level X clients. It is written entirely in Python.

This package provides JSON support files from the JSON Schema Specifications (metaschemas, vocabularies, etc.), packaged for runtime access from Python as a referencing-based Schema Registry.

python-mpv is a ctypes-based python interface to the mpv media player. It gives you more or less full control of all features of the player, just as the lua interface does.

Graphene is a Python library for building GraphQL schemas/types. A GraphQL schema describes your data model, and provides a GraphQL server with an associated set of resolve methods that know how to fetch data.

This package provides a fast, regex-based date parsing library in pure Python.

This package provides a Python library to perform a 3-way merge between strings, based on diff-match-patch. This library performs merges at a character level, as opposed to most VCS systems, which opt for a line-based approach.

This package implements a Python port of the JavaScript mdurl.

This package determines if shell has a light or dark background.

This package helps wrapping dynamic libraries in Python. It includes a pure-Python C parser and an automation library that uses C header file definitions to simplify the use of C bindings.

Cheetah is a text-based template engine and Python code generator.

Cheetah can be used as a standalone templating utility or referenced as a library from other Python applications. It has many potential uses, but web developers looking for a viable alternative to ASP, JSP, PHP and PSP are expected to be its principle user group.

Features:

1. Generates HTML, SGML, XML, SQL, Postscript, form email, LaTeX, or any other text-based format.

2. Cleanly separates content, graphic design, and program code.

3. Blends the power and flexibility of Python with a simple template language that non-programmers can understand.

4. Gives template writers full access to any Python data structure, module, function, object, or method in their templates.

5. Makes code reuse easy by providing an object-orientated interface to templates that is accessible from Python code or other Cheetah templates. One template can subclass another and selectively reimplement sections of it.

6. Provides a simple, yet powerful, caching mechanism that can dramatically improve the performance of a dynamic website.

7. Compiles templates into optimized, yet readable, Python code.

Simple, modern file watching and code reload in Python inspired by watchdog. Among the differences are a unified approach for each operating systems and an elegant approach to concurrency using threading.

1. merge - Merges collections of the same type

2. walk - Type-preserving map

3. select - Selects a part of a collection

4. take - Takes the first n items of a collection

5. first - Takes the first item of a collection

6. remove - Predicated-removes items of a collection

7. concat - Concatenates two collections

8. flatten - Flattens a collection with subcollections

9. distinct - Returns only distinct items

10. split - Predicated-splits a collection

11. split_at - Splits a collection at a given item

12. group_by - Groups items by group

13. pairwise - Pairs off adjacent items

14. partial - Partially-applies a function

15. curry - Curries a function

16. compose - Composes functions

17. complement - Complements a predicate

18. all_fn - "all" with predicate

This package provides a minimalistic evaluator of Python expression using the ast module.

This package provides a Python library with graphical symbols that can be displayed on the terminal, with color if possible, for logging purposes.

This package provides declarative command-line interfaces using argparse and dataclasses.

PyMarshal replicates the feature of (un)marshalling structs in Golang.

This package is a port of Python's built-in functools.lru_cache function for asyncio. To better handle async behaviour, it also ensures multiple concurrent calls will only result in 1 call to the wrapped function, with all awaits receiving the result of that call when it completes.

The Braintree Python SDK provides integration access to the Braintree Gateway. Braintree is a US-based payments service provider.
