Advanced Management Solutions Inc.
AMS provides the AMS REALTIME suite of enterprise software for project management, resource management, cost management and timesheets. The Python language engine is embedded in AMS REALTIME as a means of extending the products, and also as a way of enabling custom behavior and company-specific business rules to be supported.

CWI, Python's home, has used Python in, among other things, GrINS, a 20,000 line authoring environment for transportable hypermedia presentations, and a 5,000 line multimedia teleconferencing tool, as well as many many smaller programs. See the collection of multi-media project papers.

Digital Creations
A long-time sponsor of the PSA, Digital creations develops with Python - and also makes some of their Python software available for free!

ILU (it's spelled Inter-Language Unification but it's pronounced eye-loo) is a (very) CORBA-ish multi-language object interface system. It has bindings for Common Lisp, C++, ANSI C, Modula-3 and Python.

Musi-Cal(tm) is the first online calendar that provides easy access to the most up-to-date worldwide live music information: concerts, festivals, gigs and other musical events. It is maintained by Python scripts. So is their Internet Conference Calendar.

Nightmare Software, Inc.
Nightmare Software builds 32-bit Windows software with Python - and gives some away!

Ultraseek Server, Infoseek's commercial search engine product, is implemented as an elaborate multi-threaded Python program with the primitive indexing and search operations performed by a built-in module. Most of the program is written in Python, and both a built-in spider and HTTP server can be customized with additional Python code. The program contains over 11,000 lines of Python code, and the user interface is implemented with over 17,000 lines of Python-scripted HTML templates. Try it out on the Python.Org web search page or download an evaluation copy from Infoseek Software.

eGroups.com (previously Findmail)
A comprehensive public archive of Internet mailing lists, implemented in pure Python. Latest statistics from Scott Hassan: 180,000 lines of Python doing everything from a 100% dynamic website to all email delivery, pumping out 200 messages/second on a single 400 MHz Pentium!

DataViews Corporation
DataViews Corporation in Northampton, Mass., have been using Python internally quite a bit.

A group at the Lawrence Livermore National Laboratories is basing a new numerical engineering environment on Python, replacing a home-grown scripting language of ten-year standing. Paul Dubois is a central figure in that effort.

Johnson Space Center uses Python in its Integrated Planning System as the standard scripting language. Efforts are underway to develop a modular collection of tools for assisting shuttle pre-mission planning and to replace older tools written in PERL and shell dialects. Python will also be installed in the new Mission Control Center to perform auxiliary processing integrated with a user interface shell. Ongoing developments include an automated grammar based system whereby C++ libraries may be interfaced directly to Python via compiler techniques. This technology can be extended to other languages in the future.

  • WebBook: A system for presenting (big) HTML documents using HTML frames. A WebBook document is created as a set of HTML files. These files can be organized into directories and subdirectories. The names of the files and directories follOw a certain naming convetion. WebBook automates all the structural aspects of document presentation using HTML frames, leaving the author to worry only about the content. WebBook is already being used for presenting the software documentation on the internal Web.
  • WebTrack: A tool for tracking the progress of work items. WebTrack is used by individuals and groups for tracking the progress of their assignments, projects, etc.

Los Alamos National Laboratory (LANL) Theoretical Physics Division
Scientists in the Theoretical Physics Division at Los Alamos National Laboratory are using Python to control large-scale physics codes on massively parallel supercomputers, high-end servers, and clusters.

An integrated command console allows the users to interact with the environment using a combination of Python commands, mouse selections, etc. Python also provides a mechanism to directly subclass and extend the Object Domain framework. Custom editing dialogs, user defined export facilities, and many other application extensions can be realized through Python integration."

Northside Physical Therapy
NSPT uses python to translate medical insurance billing data from one format to another format which allows it to be submitted to clearing houses via a modem. There were two big benefits to our switching to python: 1) Being OO based, it allows us to create new functionality through inheritance, without breaking old functionality; 2) We're not tied to one hardware platform or OS.
