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.

python-pylatexenc is a LaTeX parser providing LaTeX-to-Unicode and Unicode-to-LaTeX conversion.

Hissp is a modular Lisp implementation that compiles to a functional subset of Python—Syntactic macro metaprogramming with full access to the Python ecosystem.

This is a library that enables automated deprecations. It offers the deprecated() decorator to wrap functions, providing proper warnings both in documentation and via Python’s warnings system, as well as the deprecation.fail_if_not_removed() decorator for test methods to ensure that deprecated code is eventually removed.

This package provides Python bindings and utilities for GeoJSON, a format for encoding geographic data structures.

This package provides metadata objects which can be used to represent common constraints such as upper and lower bounds on scalar values and collection sizes, a Predicate marker for runtime checks, and descriptions of how we intend these metadata to be interpreted. In some cases, we also note alternative representations which do not require this package.

Python's built-in itertools module implements a number of iterator building blocks inspired by constructs from APL, Haskell, and SML. more-itertools includes additional building blocks for working with iterables.

Pyro enables you to build applications in which objects can talk to each other over the network. You can just use normal Python method calls to call objects on other machines, also known as remote procedure calls (RPC).

This library provides an efficient mechanism for overloading function implementations based on the types of the arguments.

This package provides a command-line interface (CLI) to the Jinja2 template engine.

language_data is a supplement to the langcodes module, for working with standardized codes for human languages. It stores the more bulky and hard-to-index data about languages, particularly what they are named in various languages.

Pygit2 is a set of Python bindings to the libgit2 shared library.

Senf introduces a new platform native string type called fsnative. It adds functions to convert text, bytes and paths to and from that new type and helper functions to integrate it nicely with the Python stdlib.

SSHLibrary is a Robot Framework library providing support for SSH and SFTP. It has the following main usages:

• Executing commands on the remote machine, either blocking or non-blocking.

• Writing and reading in an interactive shell.

• Transferring files and directories over SFTP.

• Ensuring that files and directories exist on the remote machine.

JMESPath (pronounced “james path”) is a Python library that allows one to declaratively specify how to extract elements from a JSON document.

This package provides a network interface and IP address enumeration library in Python.

This Python library provides additional types and actions for the standard argparse library.

pybind11 is a lightweight header-only library that exposes C++ types in Python and vice versa, mainly to create Python bindings of existing C++ code. Its goals and syntax are similar to the Boost.Python library: to minimize boilerplate code in traditional extension modules by inferring type information using compile-time introspection.

validate_email can be used to verify if an email address is valid and really exists.

This module provides various memoizing collections and decorators, including variants of the Python standard library's lru_cache function decorator.

flex can be used to validate Swagger schemata.

This package provides a Python interface to iw wireless tools.

Virtualenv is a tool to create isolated Python environments.

Rope is a refactoring library for Python. It facilitates the renaming, moving and extracting of attributes, functions, modules, fields and parameters in Python source code. These refactorings can also be applied to occurrences in strings and comments.
