I think that really depends on what you are doing.  For me, it is  
exactly as Larry said.  I prototype in Python, then profile to figure  
out the slowest piece(s), and write an extension module.  Personally,  
I use Cython which makes the transition pretty trivial.  It is this  
solution (cython, that is) that convinced me to use Python over Ruby,  
or some other language, when I was moving code from Matlab.  I  
haven't regretted it since.
