warcio is a Python library to read and write the WARC format commonly used in Web archives. It is designed for fast, low-level access to web archival content, oriented around a stream of WARC records rather than files.

k5test is a library for setting up self-contained Kerberos 5 environments, and running Python unit tests inside those environments. It is based on the file of the same name found alongside the MIT Kerberos 5 unit tests.

Joblib is a set of tools to provide lightweight pipelining in Python. In particular, joblib offers: transparent disk-caching of the output values and lazy re-evaluation (memoize pattern), easy simple parallel computing logging and tracing of the execution.

cattrs is an Python library for structuring and unstructuring data. cattrs works best with attrs classes, dataclasses and the usual Python collections, but other kinds of classes can also be supported by manually registering converters.

The rawkit package provides two modules: rawkit and libraw. The rawkit module provides a high-level Pythonic interface for developing raw photos, while the libraw module provides a CTypes based interface for interacting with the low-level LibRaw C APIs.

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.

This package implements a variety of persistent homology algorithms. It provides an interface for

• computing persistence cohomology of sparse and dense data sets

• visualizing persistence diagrams

• computing lowerstar filtrations on images

• computing representative cochains

Bcrypt is a Python module which provides a password hashing method based on the Blowfish password hashing algorithm, as described in "A Future-Adaptable Password Scheme" by Niels Provos and David Mazieres.

Scrapy is a fast high-level web crawling and web scraping framework, used to crawl websites and extract structured data from their pages. It can be used for a wide range of purposes, from data mining to monitoring and automated testing.

asprin is a general framework for optimization in ASP, that allows for computing optimal stable models of logic programs by means of preferences. Some preference types are already predefined, but more can be added as logic programs.

Pifpaf is a suite of fixtures and a command-line tool that starts and stops daemons for a quick throw-away usage. This is typically useful when needing these daemons to run integration testing. It originally evolved from its precursor overtest.

This package provides access to the Stripe financial services' API. It includes a pre-defined set of classes for API resources that initialize themselves dynamically from API responses which makes it compatible with a wide range of versions of the Stripe API.

Orjson is a fast, correct JSON library for Python. It benchmarks as the fastest Python library for JSON and is more correct than the standard json library or other third-party libraries. It serializes dataclass, datetime, numpy, and UUID instances natively.

Carbon is a backend data caching and persistence daemon for Graphite. Carbon is responsible for receiving metrics over the network, caching them in memory for "hot queries" from the Graphite-Web application, and persisting them to disk using the Whisper time-series library.

Vector is a Python library for 2D and 3D spatial vectors, as well as 4D space-time vectors. It is especially intended for performing geometric calculations on arrays of vectors, rather than one vector at a time in a Python for loop.

Invoke is a Python task execution tool and library, drawing inspiration from various sources to arrive at a powerful and clean feature set. It is evolved from the Fabric project, but focuses on local and abstract concerns instead of servers and network commands.

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. It provides many tools for building any Web site. Django focuses on automating as much as possible and adhering to the don't repeat yourself (DRY) principle.

This package includes a variety of tools used to analyze persistence diagrams. It currently houses implementations of

• Persistence images

• Persistence landscapes

• Bottleneck distance

• Modified Gromov–Hausdorff distance

• Sliced Wasserstein kernel

• Heat kernel

• Diagram plotting

Captum is a model interpretability and understanding library for PyTorch. Captum contains general purpose implementations of integrated gradients, saliency maps, smoothgrad, vargrad and others for PyTorch models. It has quick integration for models built with domain-specific libraries such as torchvision, torchtext, and others.

rJSmin is a javascript minifier written in Python. The minifier is based on the semantics of jsmin.c by Douglas Crockford. The module is a re-implementation aiming for speed, so it can be used at runtime (rather than during a preprocessing step).

PyYAML is a YAML parser and emitter for Python. PyYAML features a complete YAML 1.1 parser, Unicode support, pickle support, capable extension API, and sensible error messages. PyYAML supports standard YAML tags and provides Python-specific tags that represent an arbitrary Python object.

Read one-dimensional barcodes and QR codes using the zbar library.

Features:

• Pure python

• Works with PIL / Pillow images, OpenCV / numpy ndarrays, and raw bytes

• Decodes locations of barcodes

• No dependencies, other than the zbar library itself
