Firstly, if you're simply writing a Python program, the license terms
of the Python interpreter don't matter. Your code is completely
independent, and you can closed-source it while still running it under
Python itself. Similarly, if all you're doing with those BSD-licensed
libraries is importing them, there's no problem there.

Things become a bit more complicated if you're *distributing* the
overall package - if you're creating a single installer that installs
Python, these third-party libraries, and your proprietary software. If
that bothers you, the easiest way is to simply provide installation
instructions that say "install Python from python.org yada yada", or
check with a lawyer about exactly how you're packaging everything up.

But mainly, you don't have to worry too much about the license terms
of the language interpreter, because you can run your code on a
different interpreter perfectly easily.
