Yes, if you constrain that set to simple-enough operations.
For example, a script made up of
print "hello world"
would satisfy such constraints:-).

Seriously: you can (and should) isolate the system dependencies in
separate modules. "import foo" will import different foo.py modules
(or packages etc) depending on the environment. The 'business logic'
part can be unchanged, but there's no way to avoid the two separate
implementations for the 'technology-infrastructure access' part.

A perfectly understandable concern!
