I think Python doesn't *require* any external module to be able to start.
"site.py" is searched, but may be missing. Probably the interpreter
executable alone is enough (but I've never tested it!). Anyway, most
Python users would expect all the standard modules to be available,
though... part of the usefulness of the language comes from its "batteries
As a test, you might start with a clean install, then invoke the
interpreter and look at sys.modules. The modules you find there (those
that are not built-in) would be the minimum you need to run Python. On
Windows I got this (this was not a true "clean" install, I just disabled
sitecustomize.py and unset my PYTHONSTARTUP variable): UserDict _abcoll
abc codecs copy_reg encodings functools genericpath linecache locale
ntpath os re site sre_compile sre_constants sre_parse stat types warnings.
Most of these are dependencies from "site.py"; if you omit it, the list is
even shorter (just "codecs" and the "encodings" package; note that some
modules are built-in in Windows but external on Linux).
So it looks that -apart from those few modules- you may include as much or
as few of the standard library as you want, but consider what your users
would expect to be available...
