This package provides a plugin for Pytest that enables a CSV output mode for Pytest. It can be enabled via the --csv option it adds to the Pytest command line interface (CLI).

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.

This package provides home directory fixtures for pytest.

This package provides a pytest plugin for testing console scripts.

This plugin package provides a way to include information about the system, Python installation, and select dependencies in the header of the output when running pytest. It can be used with packages that are not affiliated with the Astropy project, but is optimized for use with astropy-related projects.

Pyinstrument is a Python profiler to help you optimize your code.

This package provides a library for replying fake data to Python software under test, when they make an HTTP query.

This is a pytest plugin to help you test projects that use Trio, a friendly library for concurrency and async I/O in Python.

This package is a pytest plugin for managing VCR.py cassettes.

expecttest is a Python module for expect tests, where the initial expected value of a test can be automatically set by running the test itself.

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 module provides an xopen function that works like Python's built-in open function, but can also deal with compressed files. Supported compression formats are gzip, bzip2 and, xz, and are automatically recognized by their file extensions. The focus is on being as efficient as possible on all supported Python versions.

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

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.

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

This package provides Python CFFI bindings to the Brotli library.

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 modern and easy to use streamable zip file generator

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

This package aims to provide faster zlib and gzip compatible compression and decompression by implementing Python bindings for the ISA-L library.

Lz-string is a string compressor library for Python.

Blosc 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.

Blosc works well for compressing numerical arrays that contains data with relatively low entropy, like sparse data, time series, grids with regular-spaced values, etc.

This Python package wraps the Blosc library.

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