taking python enterprise level?...

[simn_stv]

hello people, i have been reading posts on this group for quite some
time now and many, if not all (actually not all!), seem quite
interesting.
i plan to build an application, a network based application that i
estimate (and seriously hope) would get as many as 100, 000 hits a day
(hehe,...my dad always told me to 'AIM HIGH' ;0), not some 'facebook'
or anything like it, its mainly for a financial transactions which
gets pretty busy...
so my question is this would anyone have anything that would make
python a little less of a serious candidate (cos it already is) and
the options may be to use some other languages (maybe java, C (oh
God))...i am into a bit of php and building API's in php would not be
the hard part, what i am concerned about is scalability and
efficiency, well, as far as the 'core' is concerned.

would python be able to manage giving me a solid 'core' and will i be
able to use python provide any API i would like to implement?...

im sorry if my subject was not as clear as probably should be!.
i guess this should be the best place to ask this sort of thing, hope
im so right.

Thanks
