Itemloaders is a library that helps you collect data from HTML and XML sources. It comes in handy to extract data from web pages, as it supports data extraction using CSS and XPath Selectors.

It’s specially useful when you need to standardize the data from many sources. For example, it allows you to have all your casting and parsing rules in a single place.

This package implements functionality to work with plyline. Features:

• Visvalingham-Whyatt - removes the smallest triangles formed by three consecutive points in a polyline or polygon

• Douglas-Peucker - gives a better representation of the convex hull

This is a PEP 561 type stub package for the ujson package. It can be used by type-checking tools like mypy, PyCharm, pytype etc. to check code that uses ujson.

Pure python C++ header parser that parses C++ headers in a mildly naive manner that allows it to handle many C constructs, including many (C++11 and beyond) features.

This is a small Python library that implements boolean algebra. It defines two base elements, TRUE and FALSE, and a Symbol class that can take on one of these two values. Calculations are done only in terms of AND, OR, and NOT---other compositions like XOR and NAND are emulated on top of them. Expressions are constructed from parsed strings or directly in Python.

Shellingham detects what shell the current Python executable is running in.

This package is an implementation of of bounded Levenshtein distance (Ukkonen).

Cleo allows you to create command-line commands with signature in docstring and colored output.

Shapely is a Python package for manipulation and analysis of planar geometric objects. It is based on the GEOS library.

A Flake8 plugin that checks for the line continuation style to be in the preferred method according to PEP-8, specifically:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. Long lines can be broken over multiple lines by wrapping expressions in parentheses. These should be used in preference to using a backslash for line continuation.

This package provides tools to define a command line interface from a docstring rather than the other way around.

The isoweek module provide the class Week that implements the week definition of ISO 8601. This standard also defines a notation for identifying weeks; yyyyWww (where the W is a literal). Week instances stringify to this form.

python-forex-python can be used to manipulate foreign exchange rates and to operate currency conversions.

Features:

• List all currency rates.

• BitCoin price for all currencies.

• Converting amount to BitCoins.

• Get historical rates for any day since 1999.

• Conversion rate for one currency(ex; USD to INR).

• Convert amount from one currency to other.('USD 10$' to INR).

• Currency symbols.

• Currency names.

This library helps you read text from an unknown charset encoding. Motivated by chardet, it tries to resolve the issue by taking a new approach. All IANA character set names for which the Python core library provides codecs are supported.

This package provides a library for W3C Provenance Data Model supporting PROV-O (RDF), PROV-XML, PROV-JSON import/export.

This package gives you colored strings for the terminal. Crayons automatically wraps a given string in the foreground color and restores the original state after the string is printed.

This package provides a parser to parse binary structs into dataclasses.

Macaroons, like cookies, are a form of bearer credential. Unlike opaque tokens, macaroons embed caveats that define specific authorization requirements for the target service, the service that issued the root macaroon and which is capable of verifying the integrity of macaroons it receives.

Macaroons allow for delegation and attenuation of authorization. They are simple and fast to verify, and decouple authorization policy from the enforcement of that policy.

qstylizer is a Python package designed to help with the construction of PyQt/PySide stylesheets.

This is a implementation of immutable linked lists for Python. It contains nil (the empty linked list) and a Pair class for nodes. Since a linked list is treated as immutable, it is hashable, and its length can be retrieved in constant time. Some of the terminology is inspired by LISP. It is possible to create an improper list by creating a Pair with a non-list cdr.

This library implements validation of JSON documents by JSON schema for drafts 04, 06 and 07.

Palettable (formerly brewer2mpl) is a library of color palettes for Python. It’s written in pure Python with no dependencies, but it can supply color maps for matplotlib. You can use Palettable to customize matplotlib plots or supply colors for a web application.

This package provides helpers for computing similarities between arbitrary sequences. Included metrics are Levenshtein, Hamming, Jaccard, and Sorensen distance, plus some bonuses. All distance computations are implemented in pure Python, and most of them are also implemented in C.

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.
