argcomplete provides extensible command line tab completion of arguments and options for Python scripts using argparse. It's particularly useful for programs with many options or sub-parsers that can dynamically suggest completions ; for example, when browsing resources over the network.

This tool helps to install Rust into a temporary directory, allowing support of Rust-based Python builds. Cargo and rustc are installed into a cache directory, to avoid modifying the host's environment, and further activated using a set of environment variables.

ipyparallel is a Python package and collection of CLI scripts for controlling clusters for Jupyter. ipyparallel contains the following CLI scripts:

1. ipcluster - start/stop a cluster

2. ipcontroller - start a scheduler

3. ipengine - start an engine

This package provides a Python library to perform a 3-way merge between strings, based on diff-match-patch. This library performs merges at a character level, as opposed to most VCS systems, which opt for a line-based approach.

NumPy is the fundamental package for scientific computing with Python. It contains among other things: a powerful N-dimensional array object, sophisticated (broadcasting) functions, tools for integrating C/C++ and Fortran code, useful linear algebra, Fourier transform, and random number capabilities.

Pygame-menu is a python-pygame library for creating menus and GUIs. It supports several widgets, such as buttons, color inputs, clock objects, drop selectors, frames, images, labels, selectors, tables, text inputs, color switches, and many more, with multiple options to customize.

The poetry-core module provides a PEP 517 build back-end implementation developed for Poetry. This project is intended to be a light weight, fully compliant, self-contained package allowing PEP 517 compatible build front-ends to build Poetry managed projects.

A library designed to represent tabular data in visually appealing ASCII tables. PrettyTable allows for selection of which columns are to be printed, independent alignment of columns (left or right justified or centred) and printing of sub-tables by specifying a row range.

This package includes WrapSpawner and ProfilesSpawner, which provide mechanisms for runtime configuration of spawners. The inspiration for their development was to allow users to select from a range of pre-defined batch job profiles, but their operation is completely generic.

Lexicon provides a way to manipulate DNS records on multiple DNS providers in a standardized way. It has a CLI but it can also be used as a Python library. It was designed to be used in automation, specifically with Let's Encrypt.

This is a Python library for the generation of email authentication headers. The library can perform DKIM, SPF, and DMARC validation, and the results are packaged into the Authentication-Results header. The library can DKIM and ARC sign messages and output the corresponding signature headers.

Cloudpickle makes it possible to serialize Python constructs not supported by the default pickle module from the Python standard library. It is especially useful for cluster computing where Python expressions are shipped over the network to execute on remote hosts, possibly close to the data.

This Python library is a wrapper around tokenize from the Python standard library. It provides two additional tokens ESCAPED_NL and UNIMPORTANT_WS, and a Token data type. Use src_to_tokens and tokens_to_src to roundtrip.

FFCx is a compiler for finite element variational forms. From a high-level description of the form in the Unified Form Language (UFL), it generates efficient low-level C code that can be used to assemble the corresponding discrete operator (tensor).

Matplotlib is a Python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. Matplotlib can be used in Python scripts, the python and ipython shell, web application servers, and six graphical user interface toolkits.

pandarallel allows any Pandas user to take advantage of their multi-core computer, while Pandas uses only one core. pandarallel also offers nice progress bars (available on Notebook and terminal) to get an rough idea of the remaining amount of computation to be done.

The Levenshtein Python C extension module contains functions for fast computation of

1. Levenshtein (edit) distance, and edit operations

2. string similarity

3. approximate median strings, and generally string averaging

4. string sequence and set similarity

It supports both normal and Unicode strings.

fastparquet is a Python implementation of the Parquet file format. fastparquet is used implicitly by dask, pandas and intake-parquet. It supports the following compression algorithms:

• Gzip

• Snappy

• Brotli

• LZ4

• Zstd

• LZO (optionally)

CTranslate2 is a C++ and Python library for efficient inference with Transformer models.

The project implements a custom runtime that applies many performance optimization techniques such as weights quantization, layers fusion, batch reordering, etc., to accelerate and reduce the memory usage of Transformer models on CPU and GPU.

smartpants can perform the following transformations:

1. Straight quotes ( " and ' ) into "curly" quote HTML entities

2. Backticks-style quotes (``like this'') into "curly" quote HTML entities

3. Dashes (-- and ---) into en- and em-dash entities

4. Three consecutive dots (... or . . .) into an ellipsis entity

Entry points are a way for Python packages to advertise objects with some common interface. The most common examples are console_scripts entry points, which define shell commands by identifying a Python function to run. The entrypoints module contains functions to find and load entry points.

python-lazy-loader makes it easy to load subpackages and functions on demand. Its main features are:

• Allow subpackages to be made visible to users without incurring import costs.

• Allow external libraries to be imported only when used, improving import times.

Hypothesis is a library for testing your Python code against a much larger range of examples than you would ever want to write by hand. It’s based on the Haskell library, Quickcheck, and is designed to integrate seamlessly into your existing Python unit testing work flow.

lenstronomy is a multi-purpose software package to model strong gravitational lenses. lenstronomy finds application for time-delay cosmography and measuring the expansion rate of the Universe, for quantifying lensing substructure to infer dark matter properties, morphological quantification of galaxies, quasar-host galaxy decomposition and much more.
