Use 'from ... import':

from Pyrl.Entity.Player import Player
from Pyrl.Entity.Monster.Zombie import Zombie

'from ... import *' is considered poor practice, because it imports a whole
bunch of names from the module, but most people have nothing against
importing a few specified names.  

Alan Gauld is correct that it's often clearer to have multiple classes in a
file; for example, "from Pyrl.Entity.Monster import Zombie, Vampire" would
be tidier.  That depends on the length of each class; if the Zombie class is
500 lines long, you're probably going to want to put it in a file of its
own, but if it's 3 lines or 20 lines or maybe 100 lines, you can put
multiple monster classes in a file without things becoming too ungainly.
