A library designed to represent tabular data in visually appealing ASCII tables. PrettyTable allows for selection of which columns are to be printed, independent alignment of columns (left or right justified or centred) and printing of sub-tables by specifying a row range.

The pyvips package provides Python bindings for VIPS, a multithreaded image-processing system with low memory needs.

This package provides:

• PEP 561 typing stubs packages for the Trio project packages:

  • trio (trio-stubs)

  • outcome (outcome-stubs)

  • async_generator (async_generator-stubs)

• A package trio_typing containing types that Trio programs often want to refer to (AsyncGenerator[Y, S] and TaskStatus[T]) and a mypy plugin that smooths over some limitations in the basic type hints.

This package provides a JSON toolkit for Python developers.

LibCST parses Python source code as a CST tree that keeps all formatting details (comments, whitespaces, parentheses, etc). It's useful for building automated refactoring (codemod) applications and linters. LibCST creates a compromise between an Abstract Syntax Tree (AST) and a traditional Concrete Syntax Tree (CST). By carefully reorganizing and naming node types and fields, LibCST creates a lossless CST that looks and feels like an AST.

PLY is a lex/yacc implemented purely in Python. It uses LR parsing and does extensive error checking.

Entry points are a way for Python packages to advertise objects with some common interface. The most common examples are console_scripts entry points, which define shell commands by identifying a Python function to run. The entrypoints module contains functions to find and load entry points.

xlwt is a library for writing data and formatting information to older Excel files (i.e. .xls). The package itself is pure Python with no dependencies on modules or packages outside the standard Python distribution. It is not intended as an end-user tool.

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.

This Python module implements the FLIRT. This technology is useful for identifying common library subroutines in disassembled binaries.

Sqltrie is a SQL-based prefix tree inspired by pygtrie and python-diskcache.

This package provides tools to convert files in the format used by multiple Spanish banks (standard 43 of the Spanish Banking Council [CSB43] / Spanish Banking Association [AEB43]) to other formats.

Supported output formats are: OFX, HomeBank CSV, HTML, JSON, ODS (OpenDocument spreadsheet), CSV, TSV, XLS, XLSX (Microsoft Excel spreadsheet), and YAML.

pydub makes it easy to manipulate audio in Python. It relies on ffmpeg to open various audio formats.

This package provides a Doxygen filter for Python.

This package implements a functionality for time taking using context managers.

This package corresponds to the latest unicodedata standard Python module.

If your code lets other people supply callback functions, it's important to specify the function signature you expect, and check that functions support that. Adding extra parameters later would break other peoples code unless you're careful. The backcall package provides a way of specifying the callback signature using a prototype function.

This package provides utilities for multithreading in Click applications.

This package provides a Python implementation of the CANopen standard for CANs. The aim of the project is to support the most common parts of the CiA 301 standard in a simple Pythonic interface. It is mainly targeted for testing and automation tasks rather than a standard compliant master implementation.

pykakasi is a Python Natural Language Processing NLP library to transliterate hiragana, katakana and kanji (Japanese text) into rōmaji (Latin/Roman alphabet). It can handle characters in NFC form.
