This is the official Discogs API client for Python. You can use it to query the Discogs music database for metadata on artists, releases, and more.

The argparse module was added to Python 2.7 as a replacement for optparse. The implementation of argparse supports features that would not have been easy to add to optparse, and that would have required backwards-incompatible API changes, so a new module was brought into the library instead. optparse is still supported, but is not likely to receive new features.

Hyde is a static website generator written in python. While Hyde took life as awesome Jekyll's evil twin, it has since been completely consumed by the dark side and has an identity of its own.

MComix is an user-friendly, customizable image viewer. It is specifically designed to handle comic books, but also serves as a generic viewer. It reads images in ZIP, RAR, 7Zip or tar archives as well as plain image files. It is written in Python and uses GTK+ through the PyGTK bindings, and runs on both Linux and Windows.

PyEphem provides scientific-grade astronomical computations for the Python programming language. Given a date and location on the Earth’s surface, it can compute the positions of the Sun and Moon, of the planets and their moons, and of any asteroids, comets, or earth satellites whose orbital elements the user can provide. Additional functions are provided to compute the angular separation between two objects in the sky, to determine the constellation in which an object lies, and to find the times at which an object rises, transits, and sets on a particular day.

Emacs is a huge beast. It can read email, play tetris, act as a file manager, display google maps, and even edit videos. It has support for many, many programming languages and has many features related to programming. Unfortunately, emacs doesn’t have a full programming environment for python out-of-the-box.

PyAST is a collection of modules that allows the facilities of the Starlink AST library to be used within Python (version 2.7 or later) scripts.
The AST library provides a comprehensive range of facilities for attaching world coordinate systems to astronomical data, for retrieving and interpreting that information and for generating graphical output based on it. AST is written in ANSI C but has wrappers for various other languages, including Fortran, Java, Perl, and now Python.

This is a home-brew python-mode with some excerpts from GNU/Emacs’ python.el.

It aims to provide the stuff you’ll expect from a major mode for python editing while keeping it simple.

Currently it implements:

Syntax highlighting, Indentation, Movement, Shell interaction, Shell completion, Shell virtualenv support, Pdb tracking, Symbol completion, Skeletons, FFAP, Code Check, Eldoc, imenu.

Cleans up, regularizes, and reformats the text of Python scripts.

Clint is a module filled with a set of awesome tools for developing commandline applications.

This new NumPy book provides an easy start to NumPy for those who want to churn numbers in Python programming language, whether you don't have much programming background or you are switching from your favorite language. The author of the book uses quite a friendly tone throughout the book. Most of the important aspects of NumPy is well covered with well explained examples. The examples provided are step by step explained, starting from the basic array/matrix creation to more complex tasks like signal analysis and linear algebra related calculations.

The maker is a Content Management System (CMS) for websites. the maker is running on your local computer and after you made your changes you are publishing via FTP. All that is required is some webspace with FTP access.

The Radicale Project is a complete CalDAV calendar server solution. It can store multiple calendars.

Calendars are available for both local and remote access, possibly limited through authentication policies. They can be viewed and edited by calendar clients on mobile phones or computers.

Line Identification Plots v0.1 documentation
Line identification plots with automatic label layout

This module has functions for automatically placing labels in a plot in such a way that the labels do not overlap with each other. This is very useful, for example, in creating plots that have labels identifying features in a spectrum.

Parse RSS and Atom feeds in Python. 3000 unit tests. Open source.

PyChecker is a tool for finding bugs in python source code. It finds problems that are typically caught by a compiler for less dynamic languages, like C and C++. It is similar to lint. Because of the dynamic nature of python, some warnings may be incorrect; however, spurious warnings should be fairly infrequent.

PP is a python module which provides mechanism for parallel execution of python code on SMP (systems with multiple processors or cores) and clusters (computers connected via network).

Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions. And before you ask: It's BSD licensed!

Cython is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.

Tutorial given at the Python for Scientific Computing Conference held August 18-23, 2009 at CalTech in Pasadena CA. Presented by Michael Droettboom, Space Telescope Science Institute.

The Kapteyn Package is a collection of Python modules and applications developed by the computer group of the Kapteyn Astronomical Institute, University of Groningen, The Netherlands. The purpose of the package is to provide tools for the development of astronomical applications with Python.

Ropemacs is a plugin for performing python refactorings in emacs. It uses rope library and pymacs.

The purpose of this web site is to act as a community knowledge base for performing astronomy research with Python. It provides lists of useful resources, a forum for general discussion, advice, or relevant news items, collecting users' code snippets or scripts, and longer tutorials on specific topics. The topics within these pages are presented in a list view with the ability to sort by date or topic. A traditional "blog" view of the most recently posted topics is visible from the site Home page.

APLpy (the Astronomical Plotting Library in Python) is a Python module aimed at producing publication-quality plots of astronomical imaging data in FITS format. The module uses Matplotlib, a powerful and interactive plotting package. It is capable of creating output files in several graphical formats, including EPS, PDF, PS, PNG, and SVG.

For Python programmers, I've got some suggestions on how to write a main() function that's easy to invoke in other contexts, e.g. from the interactive Python prompt when you feel like experimenting.

Pymacs is a powerful tool which, once started from Emacs, allows both-way communication between Emacs Lisp and Python. Pymacs aims Python as an extension language for Emacs rather than the other way around, and this asymmetry is reflected in some design choices. Within Emacs Lisp code, one may load and use Python modules. Python functions may themselves use Emacs services, and handle Emacs Lisp objects kept in Emacs Lisp space.

astLib is a set of Python modules that provides some tools for research astronomers. It can be used for astronomical plots, some statistics, common calculations, coordinate conversions, and manipulating FITS images with World Coordinate System (WCS) information through PyWCSTools - a simple wrapping of WCSTools by Doug Mink. PyWCSTools is distributed (and developed) as part of astLib.

Here’s how to plot x or y errorbars (or both) and how to customize the resulting plot.

After I’ve covered basic plotting using matplotlib in this part I’ll show you two ways to display histograms of some data.

Contactsheet is a python script that generates a contactsheet or index print containing a configurable number of images. If there are more images than fits on the page, new contactsheets are created. Also, the image name to the images can be printed.

I enjoy a variety of geeky interests while living happily with my wife Erin—an amazing linguist, crafter, and artist—in sunny San Diego, California.

I’ve written several extensions for Emacs including its JSON parser and its LiveJournal client, ljupdate. I also contribute to ERC, an Emacs IRC client, and run Planet Emacsen. When not playing with Emacs, I run San Diego’s Django user group, I write code, and I contribute to 50ft, a local design blog.

I do some Python coding on my own, and so I have a few python customizations. Python-mode now comes with GNU Emacs, and so these work pretty much out-of-the-box. However, this does not get autoloaded, so you have to put the following before modifying python-mode-map or python-mode-hook.
