An import statement always imports a module, but Python also has the
from...import statement to import one item from a module:

from core.fleet import Fleet
f = Fleet()

The convention is to use the name "Fleet" (with an initial capital)
for the class and "fleet" (all lower case) for the module.  This
makes it easier to not confuse the class and the module.

Hope this helps,
