The pyparsing module is an alternative approach to creating and executing simple grammars, vs. the traditional lex/yacc approach, or the use of regular expressions. The pyparsing module provides a library of classes that client code uses to construct the grammar directly in Python code.

The Unified Form Language (UFL) is a domain specific language for declaration of finite element discretizations of variational forms. More precisely, it defines a flexible interface for choosing finite element spaces and defining expressions for weak forms in a notation close to mathematical notation.

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.

DJI Tello drone Python interface using the official Tello SDK and Tello EDU SDK. This library has the following features:

• Implementation of all tello commands

• Retrieve a video stream easily

• Receive and parse state packets

• Control a swarm of drones.

The flufl.lock package provides NFS-safe file locking with timeouts for POSIX systems. It is similar to the O_EXCL option of the open system call but uses a lockfile. Lock objects support lock-breaking and have a maximum lifetime built-in.

This packge provides utilities to retrieve tile maps from the internet. It can add those tiles as basemap to matplotlib figures or write tile maps to disk into geospatial raster files. Bounding boxes can be passed in both WGS84 (EPSG:4326) and Spheric Mercator (EPSG:3857).

spacetrack is a python module for Space-Track which promotes space flight safety, protection of the space environment and the peaceful use of space worldwide by sharing space situational awareness services and information with international satellite owners/operators, academia and other entities.

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

Kiwi is an efficient C++ implementation of the Cassowary constraint solving algorithm. Kiwi has been designed from the ground up to be lightweight and fast. Kiwi ranges from 10x to 500x faster than the original Cassowary solver with typical use cases gaining a 40x improvement. Memory savings are consistently > 5x.

SQLAlchemy is the Python SQL toolkit and ORM that gives application developers the full power and flexibility of SQL. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

Zope.proxy provides generic, transparent proxies for Python. Proxies are special objects which serve as mostly-transparent wrappers around another object, intervening in the apparent behavior of the wrapped object only when necessary to apply the policy (e.g., access checking, location brokering, etc.) for which the proxy is responsible.

Css-parser is a Python package for parsing and building CSS Cascading Style Sheets. Currently it provides a DOM only and no rendering options.

It's a fork of cssutils 1.0.2, updated and modified for parsing ebooks, due to cssutils not receiving updates as of 1.0.2.

This Python library provides tools to deal with email and mailboxes over IMAP:

• Parsed email message attributes

• Query builder for searching emails

• Work with emails in folders (copy, delete, flag, move, seen)

• Work with mailbox folders (list, set, get, create, exists, rename, delete, status)

Pyrsistent is a number of persistent collections (by some referred to as functional data structures). Persistent in the sense that they are immutable.

All methods on a data structure that would normally mutate it instead return a new copy of the structure containing the requested updates. The original structure is left untouched.

PyWavelets is a library for wavelet transforms in Python. Wavelets are mathematical basis functions that are localized in both time and frequency. Wavelet transforms are time-frequency transforms employing wavelets. They are similar to Fourier transforms, the difference being that Fourier transforms are localized only in frequency instead of in time and frequency.

This package provides the Shopify API for Python.

The ShopifyAPI library allows Python developers to programmatically access the admin section of stores using an ActiveResource-like interface similar the ruby Shopify API gem. The library makes HTTP requests to Shopify in order to list, create, update, or delete resources (e.g. Order, Product, Collection).

This package provides a quick single file library for easily adding evaluatable expressions into python projects. Say you want to allow a user to set an alarm volume, which could depend on the time of day, alarm level, how many previous alarms had gone off, and if there is music playing at the time.

Soup Sieve is a CSS selector library designed to be used with Beautiful Soup 4. It aims to provide selecting, matching, and filtering using modern CSS selectors. Soup Sieve currently provides selectors from the CSS level 1 specifications up through the latest CSS level 4 drafts and beyond (though some are not yet implemented).

This is a package for image processing with Dask arrays. Features:

• Provides support for loading image files.

• Implements commonly used N-D filters.

• Includes a few N-D Fourier filters.

• Provides some functions for working with N-D label images.

• Supports a few N-D morphological operators.

Accelerate was created for PyTorch users who like to write the training loop of PyTorch models but are reluctant to write and maintain the boilerplate code needed to use multi-GPUs/TPU/fp16. It abstracts exactly and only the boilerplate code related to multi-GPUs/TPU/fp16 and leaves the rest of your code unchanged.
