Python Written in C?

I think your mixing things up. Even modern C compiler are mostly written
in some other high level language. See GCC, for instance: it's mostly
written in C.

Many languages are made for build other major systems:
* C was made in order to ease the build of Unix
* Ada was made in order to ease the build of Air Traffic Control Systems.
* and so on...

On the other hand, Python's language features are, in a way, orthogonal
to those of the underlying language in which Python *may* be implemented
(take a look at PyPy: http://en.wikipedia.org/wiki/PyPy).

I mean, I really don't care how Python mappings are implemented in C.
What I care about is that I think in terms of (key, value) mappings,
regardless of how lookups, insertions, deletions, and so are made
internally. In C, I would have to resort to implement a hash table or so.

Let's summarize: Python is a *new* language. C was the option to make it
happen, there are others.
