While Piet's explanation is correct for the logging module, you'll
also see examples like:
import os
import os.path
Where os.path _is_ accessible via the original os import.
I believe that in this case, os.path is imported and stored against
'os.path', so any further references to it will be handled by the
standard module lookup, rather than having to look up the 'os' import
and then use getattr to reach path. I would expect that this is mostly
of interest if you were using os.path.methods in an inner loop, to
reduce the number of lookups.
