This package provides a wrapper for the nested containment list data structure. It is a static interval-tree that is fast for both construction and lookups.

This package provides an ANSI terminal tool for Python, colored shell and other handy fancy features.

inotify-simple is a simple wrapper around inotify library.

The library allows a process to change its title (as displayed by system tools such as ps and top).

Changing the title is mostly useful in multi-process systems, for example when a master process is forked: changing the children's title allows identifying the task each process is busy with. The technique is used by PostgreSQL and the OpenSSH Server for example.

This library helps to redirect sys.stdout to a stream or a file while executing some piece of code, including C code running within a Python process.

This library allows the user to define a command-line interface from a program's help message rather than specifying it programmatically with command-line parsers like getopt and argparse.

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.

Schematics is a Python library to combine types into structures, validate them, and transform the shapes of your data based on simple descriptions.

The internals are similar to ORM type systems, but there is no database layer in Schematics. Instead, building a database layer is easily made when Schematics handles everything except for writing the query. Schematics can be used for tasks where having a database involved is unusual.

This package provides a pure Python QR Code generator module. It uses the Python Imaging Library (PIL) to allow for the generation of QR Codes.

In addition this package provides a command line tool to generate QR codes and either write these QR codes to a file or do the output as ascii art at the console.

This Python package provides progress reporting for visual of progress of long running operations. There are multiple choices of progress bars and spinners, with customizable options, such as width, fill character, and suffix.

The mercantile module provides ul(xtile, ytile, zoom) and bounds(xtile, ytile, zoom) functions that respectively return the upper left corner and bounding longitudes and latitudes for XYZ tiles, a xy(lng, lat) function that returns spherical mercator x and y coordinates, a tile(lng, lat, zoom) function that returns the tile containing a given point, and quadkey conversion functions quadkey(xtile, ytile, zoom) and quadkey_to_tile(quadkey) for translating between quadkey and tile coordinates.

EmPy is a system for embedding Python expressions and statements in template text; it takes an EmPy source file, processes it, and produces output. This is accomplished via expansions, which are special signals to the EmPy system and are set off by a special prefix (by default the at sign, @). EmPy can expand arbitrary Python expressions and statements in this way, as well as a variety of special forms. Textual data not explicitly delimited in this way is sent unaffected to the output, allowing Python to be used in effect as a markup language. Also supported are callbacks via hooks, recording and playback via diversions, and dynamic, chainable filters. The system is highly configurable via command line options and embedded commands.

This package implements object-oriented JSONSchema. It lets you traverse a schema like paths and access a schema on demand with separate dereferencing accessor layer.

Deterministically encode JSON.

• Encodes objects and arrays as RFC 7159 JSON.

• Sorts object keys so that you get the same result each time.

• Has no insignificant whitespace to make the output as small as possible.

• Escapes only the characters that must be escaped, U+0000 to U+0019 / U+0022 / U+0056, to keep the output as small as possible.

• Uses the shortest escape sequence for each escaped character.

• Encodes the JSON as UTF-8.

• Can encode frozendict immutable dictionaries.

python-pywatchman is a library to connect and query Watchman to discover file changes.

This package provides the rnc2rng command-line tool as well as a Python library to convert RELAX NG schemata in Compact syntax (rnc) to equivalent schemata in the XML-based default RELAX NG syntax.

Itsdangerous provides various helpers to pass trusted data to untrusted environments and back.

The PyPNG module implements support for PNG images. It reads and writes PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 bits per pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, RGBA, LA (greyscale with alpha) with 8/16 bits per channel; colour mapped images (1/2/4/8 bit). Adam7 interlacing is supported for reading and writing. A number of optional chunks can be specified (when writing) and understood (when reading): tRNS, bKGD, gAMA.

PyPNG is not a high level toolkit for image processing (like PIL) and does not aim at being a replacement or competitor. Its strength lies in fine-grained extensive support of PNG features. It can also read and write Netpbm PAM files, with a focus on its use as an intermediate format for implementing custom PNG processing.

This is a Python package for easy throttling with asyncio support.

This package helps wrapping dynamic libraries in Python. It includes a pure-Python C parser and an automation library that uses C header file definitions to simplify the use of C bindings.

Parso is a Python parser that supports error recovery and round-trip parsing for different Python versions (in multiple Python versions). Parso is also able to list multiple syntax errors in your Python file.

YAPF is a formatter for Python code. It's based off of clang-format, developed by Daniel Jasper. In essence, the algorithm takes the code and reformats it to the best formatting that conforms to the style guide, even if the original code didn't violate the style guide.

This package implements a functionality to print versions of imported Python packages.

pyinotify provides a Python interface for monitoring file system events on Linux.
