python for commercial desktop software

Are there any examples of python being used in commercial software for windows? Or open source?

I wanted to make a windows program hwhich i am gonna sale in python but im not sure what the performance would be like.

cheers

SpamBayes is an open source plugin for Outlook written in Python, it has a very good Windows installer.

python is also used as the scripting engine in many commercial games - performance is hard to judge there, but it's good enough to be integrated into the game engine.

Python is more than fast enough to be used for desktop software

Another example, this time a pretty expensive comercial program that embeds/extends the the Python interpreter: Maxons Cinema 4D.

One other reason to use Python and not worry about speed, if your program is too slow you can always rewrite part of it in C. Or, if you don't want to do this there are several projects aimed at speeding Python up:

Have fun,

This one of the few things I would say against Python:

If you are really paranoid and want to keep IPR then Python is probably not the language to use in a really commercially sensitive module. You can protect it to some degree using obfuscation but it is possible to "de-compile" the code more easily than say C.
