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.

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.

pybids provides a set of tools for working with BIDS datasets. The BIDS standard aims at organizing and describing neuroimaging data in a uniform way in order to facilitate data sharing within the scientific community.

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.

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

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.

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.

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

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.

Bandit is a tool designed to find common security issues in Python code. To do this Bandit processes each file, builds an AST from it, and runs appropriate plugins against the AST nodes. Once Bandit has finished scanning all the files it generates a report.

Pydbus provides a pythonic interface to the D-Bus message bus system. Pydbus can be used to access remote objects and also for object publication. It is based on PyGI, the Python GObject Introspection bindings, which is the recommended way to use GLib from Python.

diemPy is a computational tool designed to polarize genomic data for hybrid zone analysis. The package implements an expectation-maximization (EM) algorithm to determine the optimal polarization of genetic markers, enabling researchers to identify and analyze patterns of introgression and hybridization in genomic datasets.

Pydbus provides a pythonic interface to the D-Bus message bus system. Pydbus can be used to access remote objects and also for object publication. It is based on PyGI, the Python GObject Introspection bindings, which is the recommended way to use GLib from Python.

PyStoG is a Python package for converting between different total scattering functions used in crystalline and amorphous materials research. It handles reciprocal-space structure factors and real-space pair distribution functions, performing Fourier transforms between them and applying filters to remove spurious artifacts in the data.

Python module that implements DKIM (DomainKeys Identified Mail) email signing and verification (RFC6376). It also provides helper scripts for command line signing and verification. It supports DKIM signing/verifying of ed25519-sha256 signatures (RFC 8463). It also supports the RFC 8617 Authenticated Received Chain (ARC) protocol.

This library brings the Olson tz database into Python. It allows accurate and cross platform timezone calculations using Python 2.4 or higher. It also solves the issue of ambiguous times at the end of daylight saving time. Almost all of the Olson timezones are supported.

CVXOPT is a package for convex optimization based on the Python programming language. Its main purpose is to make the development of software for convex optimization applications straightforward by building on Python’s extensive standard library and on the strengths of Python as a high-level programming language.

Pandas is a Python package providing fast, flexible, and expressive data structures designed to make working with structured (tabular, multidimensional, potentially heterogeneous) and time series data both easy and intuitive. It aims to be the fundamental high-level building block for doing practical, real world data analysis in Python.

ACME is Automatic Certificate Management Environment, a protocol that allows clients and certificate authorities to automate verification and certificate issuance. The ACME protocol is used by the free Let's Encrypt Certificate Authority.

txacme is an implementation of the protocol for Twisted, the event-driven networking engine for Python.

This package provides Python bindings for the Libdiscid library. The main purpose is the calculation of Disc IDs for use with the MusicBrainz database. Additionally the disc Media Catalog Number (MCN) and track International Standard Recording Code (ISRC) can be extracted.
