pyramid_tm is a package which allows Pyramid requests to join the active transaction as provided by the Python transaction package.

frozendict is an immutable wrapper around dictionaries that implements the complete mapping interface. It can be used as a drop-in replacement for dictionaries where immutability is desired.

This Python package can be used to read and write SAS, SPSS and Stata files into/from Pandas DataFrames. It is a wrapper around the C library readstat.

scvi-tools (single-cell variational inference tools) is a package for probabilistic modeling and analysis of single-cell omics data, built on top of PyTorch and AnnData.

PhenoGraph is a clustering method designed for high-dimensional single-cell data. It works by creating a graph representing phenotypic similarities between cells and then identifying communities in this graph.

Scikit-opt (or sko) is a Python module implementing swarm intelligence algorithms: genetic algorithm, particle swarm optimization, simulated annealing, ant colony algorithm, immune algorithm, artificial fish swarm algorithm.

pynetdicom is a Python package that implements the DICOM networking protocol. It allows the easy creation of DICOM SCUs and SCPs.

This driver is based on black box reverse engineering of the USB behaviour of the proprietary software, and reading the basic data structure layouts in the original python-can canalystii source.

This library contains the HTTP/2 framing code used in the hyper project. It provides a pure-Python codebase that is capable of decoding a binary stream into HTTP/2 frames.

Python LiveReload provides a command line utility, livereload, for starting a web server in a directory. It can trigger arbitrary commands and serve updated contents upon changes to the directory.

rst.linker automatically replaces text by a reStructuredText external reference or timestamps. It's primary purpose is to augment the changelog, but it can be used for other documents, too.

This package provides a pixel-level image comparison library for Python, originally created to compare screenshots in tests. Its features include accurate anti-aliased pixels detection and perceptual color difference metrics.

Pyresample is a python package for resampling geospatial image data. Resampling or reprojection is the process of mapping input geolocated data points to a new target geographic projection and area.

Scripttest is a Python helper library for testing interactive command-line applications. With it you can run a script in a subprocess and see the output as well as any file modifications.

This package provides a library that wraps the traditional Python dictionaries and provides a syntax to access nested dictionaries values using a dot syntax, for example: dictionary['deeply.nested.key'].

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).

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.

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.

WhiteNoise allows your web app to serve its own static files, making it a self-contained unit that can be deployed anywhere without relying on nginx, Amazon S3 or any other external service.

This package provides a Quart extension to provide Trio support. This is an alternative to using the asyncio event loop present in the Python standard library and supported by default in Quart.

Cloud-init is the multi-distribution method for cross-platform cloud instance initialization. It is supported across all major public cloud providers, provisioning systems for private cloud infrastructure, and bare-metal installations.

This is a fork of the standard library modules cgi and cgitb. They are slated to be removed from the Python standard library in Python 3.13 by PEP-594.

This package provides a framework for working with formal language grammars. The library was originally developed for educational purposes and therefore implements many textbook algorithms regarding the manipulation and interaction with formal grammars.
