There are various packagers out there that can wrap up your python
script with the interpreter and any library files necessary to run it.
I would bet the result is far less than 100 MB.  I'm sure you could
develop a python application that would use all 100 MB of the files that
comprise the standard library and the helper libraries if you really tried.

I'm not up to date on the latest packagers, but I know at one time folks
used py2exe, and some used cx_freeze.
