This package provides a simple implementation of contracts for Python. Contracts are a debugging and verification tool. They are declarative statements about what states a program must be in to be considered "correct" at runtime. They are similar to assertions, and are verified automatically at various well-defined points in the program. Contracts can be specified on functions and on classes.

Coveralls.io is a service for publishing code coverage statistics online. This package provides seamless integration with coverage.py (and thus pytest, nosetests, etc...) in Python projects.

robotframework-jsonlibrary is a Robot Framework test library for manipulating JSON Object. You can manipulate your JSON object using JSONPath

This package provides the stestr command, a parallel Python test runner built around subunit. It is designed to execute unittest test suites using multiple processes to split up execution of a test suite. It will also store a history of all test runs to help in debugging failures and optimizing the scheduler to improve speed.

Bandit is a tool designed to find common security issues in Python code. To do this Bandit processes each file, builds an AST from it, and runs appropriate plugins against the AST nodes. Once Bandit has finished scanning all the files it generates a report.

This package provides a Python implementation of the Java library of the same name. It eases monkey patching, for example to stub out side effects when unit testing.

This package implement a pure Python module for uncompressing LZW files (.Z), such as the ones created by Unix's shell tool compress.

This package provides a pathlib-compatible Zipfile object wrapper. It provides a backport of the Path object.

Bitshuffle is an algorithm that rearranges typed, binary data for improving compression, as well as a python/C package that implements this algorithm within the Numpy framework.

This package provide a Python wrapper to EWAH compression bitarray method.

This package provides thin Python bindings to compression and decomporession algorithms implemented in Rust. This allows for using algorithms such as Snappy without additional system dependencies. The following algorithms are available:

• Snappy

• Brotli

• Bzip2

• LZ4

• Gzip

• Deflate

• Zstd

This project provides Python bindings for interfacing with the Zstandard compression library. A C extension and CFFI interface are provided.

pylsqpack is a wrapper around the ls-qpack library. It provides Python Decoder and Encoder objects to read or write HTTP/3 headers compressed with QPACK.

This package provides Python CFFI bindings to the Brotli library.

The inflate64 package provides Deflater and Inflater classes to compress and decompress with the Enhanced Deflate compression algorithm.

This package provides a modern and easy to use streamable zip file generator

MultiVolumefile is a Python library that provides a file-object abstraction, making it possible to use multiple files as if they were a single file.

This package provides a Python interface to the brotli package, an implementation of the Brotli lossless compression algorithm.

Bitshuffle is an algorithm that rearranges typed, binary data for improving compression, as well as a python/C package that implements this algorithm within the Numpy framework.

This package provides an implementation of the Branch / Call / Jump conversion filter by CFFI for Python.

This package provides Python bindings to the Zstandard (zstd) compression library. The API is similar to Python's bz2/lzma/zlib module.

This package provides py7zr, which implements 7-zip archive compression, decompression, encryption and decryption in Python.

Blosc2 is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() system call.

Python-Blosc2 wraps the C-Blosc2 library, and it aims to leverage its new API so as to support super-chunks, multi-dimensional arrays, serialization and other features introduced in C-Blosc2.

Python-Blosc2 also reproduces the API of Python-Blosc and is meant to be able to access its data, so it can be used as a drop-in replacement.

Python-LZO provides Python bindings for LZO, i.e. you can access the LZO library from your Python scripts thereby compressing ordinary Python strings.
