versioneer is a tool for managing a recorded version number in distutils-based python projects. The goal is to remove the tedious and error-prone "update the embedded version string" step from your release process.

Imagecodecs is a Python library that provides block-oriented, in-memory buffer transformation, compression, and decompression functions for use in the tifffile, czifile, and other scientific image input/output modules.

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

The Scooby package reports the following information about the currently running system:

• operating system name;

• hardware information including machine type (e.g., i386, x86_64, etc.), CPU count and total RAM;

• Python environment (e.g., Python, IPython, etc.);

• file system name;

• Python version;

• versions of specified Python packages.

It can generate reports as HTML tables or plain text lists.

Scooby has no required dependencies, and only few optional dependencies.

The simplegeneric module lets you define simple single-dispatch generic functions, akin to Python’s built-in generic functions like len(), iter() and so on. However, instead of using specially-named methods, these generic functions use simple lookup tables, akin to those used by e.g. pickle.dump() and other generic functions found in the Python standard library.

ContourPy is a Python library for calculating contours of 2D quadrilateral grids. It is written in C++11 and wrapped using pybind11.

Awkward CPP provides precompiled routines for the awkward package. It is not useful on its own, only as a dependency for awkward.

This package provides file support for setuptools declarative setup.cfg.

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

yamlordereddictloader is a Python package that provides a loader and a dumper for PyYAML allowing to keep items order when loading a file (by putting them in OrderedDict objects) and to manage OrderedDict objects when dumping to a file.

This is a collection of well-tested, simple modules and functions that aim to reduce boilerplate when working with data.

Ubelt is a small library of simple functions that extend the Python standard library. It includes an API to simplify common problems such as caching, timing, computing progress, among other things.

This module provides a portable way of finding out where user data should be stored on various operating systems.

The pip-run command provides on-demand temporary package installation for a single interpreter run. It replaces this series of commands:

$ virtualenv --python pythonX.X --system-site-packages /tmp/env
$ /tmp/env/bin/pip install pkg1 pkg2 -r reqs.txt
$ /tmp/env/bin/python ...
$ rm -rf /tmp/env

Git Hammer is a statistics tool for projects in git repositories. Its major feature is tracking the number of lines authored by each person for every commit, but it also includes some other useful statistics.

This package provides a shim of the shutil.which function that's designed to work across multiple versions of Python.

This module lets you draw large letter from ordinary characters in pure Python.

Gorilla is a Python library that provides a convenient approach to monkey patching. Monkey patching is the process of modifying module and class attributes at runtime with the purpose of replacing or extending third-party code.

Psycopg is a PostgreSQL database adapter for the Python programming language. Its main features are the complete implementation of the Python DB API 2.0 specification and the thread safety (several threads can share the same connection). It was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a large number of concurrent INSERTs or UPDATEs.

Psycopg 2 is mostly implemented in C as a libpq wrapper, resulting in being both efficient and secure. It features client-side and server-side cursors, asynchronous communication and notifications, COPY TO/COPY FROM support. Many Python types are supported out-of-the-box and adapted to matching PostgreSQL data types; adaptation can be extended and customized thanks to a flexible objects adaptation system.

Psycopg 2 is both Unicode and Python 3 friendly.

This package provides a Python library for the bsdiff binary diff utility. It also provides two command-line tools, bsdiff4 and bspatch4.

This package provides a decorator that raises an error when an operation takes longer than expected.

This package is a tool for cross-compiling extension modules. It creates a special virtual environment such that pip or setup.py will cross compile packages for you, usually with no further work on your part.

This Python tool figures out the differences between two similar XML files, in the same way the diff utility does it.

Pox provides a collection of utilities for navigating and manipulating file systems. This module is designed to facilitate some of the low-level operating system interactions that are useful when exploring a file system on a remote host. Pox provides Python equivalents of several shell commands such as which and find. These commands allow automated discovery of what has been installed on an operating system, and where the essential tools are located.
