Are there any other uses for Python\'s \"from\" keyword aside from import statements?
import
No and yes.
According to the official Python 2.7.2 grammar, the only occurrence of the word from is in the clause import_from, so no.
from
import_from
In the Python 3.1.3 grammar a new clause
raise_stmt: 'raise' [test ['from' test]]
appears, so yes.
