This package provides a mutable, self-balancing interval tree implementation for Python. Queries may be by point, by range overlap, or by range envelopment. This library was designed to allow tagging text and time intervals, where the intervals include the lower bound but not the upper bound.

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.

identify is a file identification library for Python. Given a file (or some information about a file), return a set of standardized tags identifying what the file is.

Clone non-relocatable virtualenvs without breaking site-packages.

The ResolveLib library provides a Resolver class that includes dependency resolution logic.

Modern datetime library for Python. Supports:

• DST-safe arithmetic

• Nanosecond precision

• Date arithmetic

Click is a Python package for creating command line interfaces in a composable way with as little code as necessary. Its name stands for "Command Line Interface Creation Kit". It's highly configurable but comes with sensible defaults out of the box.

This package provides provides drop-in replacements for the Python built-in int and float that are on par or faster with the Python equivalents.

This package provides a tokenizer/parser/executor for the PartiQL language, in Python.

This package provides a parser for and generator of the Git fastimport format.

This package provides a parser based on lib2to3 producing docspec data from Python source code.

This is a fork of amqplib which was originally written by Barry Pederson. It is maintained by the Celery project, and used by kombu as a pure python alternative when librabbitmq is not available.

PythonLibCore provides tools for creating larger test libraries for Robot Framework using Python. The Robot Framework hybrid and dynamic library APIs give more flexibility for library than the static library API, but they also set requirements for libraries which need to be implemented in the library side. PythonLibCore eases the problem by providing a simpler interface and by handling all the requirements towards the Robot Framework library APIs.

pdfminer.six is a community maintained fork of the original PDFMiner. It is a tool for extracting information from PDF documents. It focuses on getting and analyzing text data. Pdfminer.six extracts the text from a page directly from the sourcecode of the PDF. It can also be used to get the exact location, font or color of the text.

This package provides an efficient and elegant inotify (Linux filesystem activity monitor) library for Python.

Pexpect is a pure Python module for spawning child applications; controlling them; and responding to expected patterns in their output. Pexpect works like Don Libes’ Expect. Pexpect allows your script to spawn a child application and control it as if a human were typing commands.

Pox provides a collection of utilities for navigating and manipulating file systems. This module is designed to facilitate some of the low-level operating system interactions that are useful when exploring a file system on a remote host. Pox provides Python equivalents of several shell commands such as which and find. These commands allow automated discovery of what has been installed on an operating system, and where the essential tools are located.

Cheetah is a text-based template engine and Python code generator.

Cheetah can be used as a standalone templating utility or referenced as a library from other Python applications. It has many potential uses, but web developers looking for a viable alternative to ASP, JSP, PHP and PSP are expected to be its principle user group.

Features:

1. Generates HTML, SGML, XML, SQL, Postscript, form email, LaTeX, or any other text-based format.

2. Cleanly separates content, graphic design, and program code.

3. Blends the power and flexibility of Python with a simple template language that non-programmers can understand.

4. Gives template writers full access to any Python data structure, module, function, object, or method in their templates.

5. Makes code reuse easy by providing an object-orientated interface to templates that is accessible from Python code or other Cheetah templates. One template can subclass another and selectively reimplement sections of it.

6. Provides a simple, yet powerful, caching mechanism that can dramatically improve the performance of a dynamic website.

7. Compiles templates into optimized, yet readable, Python code.

This Python module lets you correctly generate plurals, singular nouns, ordinals, indefinite articles; it also can convert numbers to words.

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

This package provides an implementation of a topological sort algorithm.

This package provides python utilities to automatically color uncaught exception tracebacks.

This package provides a Python library with graphical symbols that can be displayed on the terminal, with color if possible, for logging purposes.

This package provides Python bindings for the libheif library and a plugin for Pillow.
