  This question is asked here frequently.  It is answered in the archives
and the FAQ.

  Luckily, Python isn't a "scripting engine".  It's a programming language. 
It scales to large projects easily.

  I think you're right.

  I don't know what kind of applications you're thinking of, but I've
developed a couple "client-side" apps in Python that were also scriptable in
Python.  It's all pretty straightforward.  The one thing Python can't give
you (yet) that some of those "scripting engines" might offer is something
resembling a secure, restricted execution environment.

  Hope this helps,
