Python.h: Why?

I'm a Python n00b. My largest Python project to date is a bubble sort in the interactive shell. That said, if there's a FAQ that answers this, please point me to it -- though, don't point me to the Python/C docs, I'm reading those now.

What kind of project benefits from having Pythin embedded in it? Are there any examples out there to look at? I'm not knocking the fact you can do it, just curious as to the why.

Thanks.
