where are the program that are written in python?

[Deep_Feelings]

python is not a new programming language ,it has been there for the
last .... 15+ years or so ? right ?

however by having a look at this page http://wiki.python.org/moin/Applications
i could not see many programs written in python (i will be interested
more in COMMERCIAL programs written in python ). and to be honest ,i
tried some of the programs in that list and all the programs that i
tried either dead projects or so buggy !

1- where are the programs that is written in python ?
2- python is high productivity language : why there are no commercial
programs written in python ?

is python a valid practical programming language ?
why it is not used in commercial software ?

please don't mention programs where python was used as a glue ,those
programs are not actually written in python.

any help will be appreciated

thank you
