Black is the uncompromising Python code formatter.

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.

This package provides the Abseil Python Common Libraries, a collection of Python libraries for building Python applications.

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

validate_email can be used to verify if an email address is valid and really exists.

A Procfile is a file which describes how to run an application consisting of several processes. honcho starts all listed processes. The output of all running processes is collected by honcho and displayed.

This package provides tools to draw Python object reference graphs with graphviz.

bson is a Python library implementing a BSON (Binary JSON) codec.

This package provides a Python library used to launch a subprocess in a pseudo terminal (pty), and interact with both the process and its pty.

Helpdev is a library to easily extract information about the Python environment.

This package provides an object type which efficiently represents an array of booleans. Bitarrays are sequence types and behave very much like usual lists. Eight bits are represented by one byte in a contiguous block of memory. The user can select between two representations: little-endian and big-endian. All of the functionality is implemented in C. Methods for accessing the machine representation are provided. This can be useful when bit level access to binary files is required, such as portable bitmap image files. Also, when dealing with compressed data which uses variable bit length encoding, you may find this module useful.

oj is a command line tool to help solving problems on various online judges. This command automates downloading sample cases, generating additional test cases, testing for your code, and submitting it.

Usage of Python's multiprocessing package in a gevent-powered application may raise problems. With gipc, process-based child processes can safely be created anywhere within a gevent-powered application.

This package provides a Doxygen input filter for QML files.

This module defines a decorator to wrap legacy APIs. The primary use case is APIs defined before keyword-only parameters existed.

Bpython is a fancy interface to the Python interpreter. bpython's main features are

1. in-line syntax highlighting,

2. readline-like autocomplete with suggestions displayed as you type,

3. expected parameter list for any Python function,

4. "rewind" function to pop the last line of code from memory and re-evaluate,

5. send the code you've entered off to a pastebin,

6. save the code you've entered to a file, and

7. auto-indentation.

Library to make reading, writing and modifying both binary and ascii STL files, file format native to the stereolithography CAD software created by 3D Systems, easy.

This package provides the reference implementation of the Jupyter Notebook format and Python APIs for working with notebooks.

This package provides an implementation-agnostic implementation of JSON reference resolution.

python-gphoto2 is a comprehensive Python interface (or binding) to libgphoto2. It is built using SWIG to automatically generate the interface code.

Distlib is a library which implements low-level functions that relate to packaging and distribution of Python software. It is intended to be used as the basis for third-party packaging tools.

This package provides the following PyHamcrest test matchers, that enable matching a protocol buffer message:

equals_proto

Test the argument equals the given protobuf message.

approximately

Test the argument equals the given protobuf message, while comparing any float field using approximation.

ignoring_field_paths

Test the argument equals the given protobuf message, while ignoring those fields specified in the field paths.

ignoring_repeated_field_ordering

Test the argument equals the given protobuf message, ignoring the ordering of any repeated field.

partially

Test the argument partially equals the given protobuf message, i.e. if a field is in the argument but not in the expected message, it's ignored in the comparison.

This package provides an AST unparser for Python. It is a factored out version of unparse found in the Python source distribution.

cattrs is an Python library for structuring and unstructuring data. cattrs works best with attrs classes, dataclasses and the usual Python collections, but other kinds of classes can also be supported by manually registering converters.
