I have an instance of a class that i set the value to 'self.world' inside a class named 'zeus' inside a module named 'Greek_gods'. and i have another class names 'World' inside a module name 'World'.

How can i tell zeus to go to 'World' and get the instance self.world?

#module named World
class World():def __init__(self):self.world = Atlas()#module named Greek_gods
class zeus():def __init__(self)

You can't, because you cannot know the world instance to be added in Zeus at the moment you create Zeus.

However, you can pass an instance of World for Zeus. There are various ways to do it:

• Pass World as a parameter to the constructor:

  #module named greek_gods
  class Zeus(object):def __init__(self, world):self.world = Atlas()world = World()
  zeus = Zeus(world)
  

• You can make World to create Zeus:

  #module named World
  class World(object):def __init__(self, world):self.world = Atlas()def create_zeus(self):zeus = Zeus()      # It would be better to pass it as a constructor zeus.world = world # parameter but let us leave it simple# Using your classes:world = World()zeus = World.create_zeus()
  

• You can create one special instance of World in the world module:

  #module named World
  class World(object):def __init__(self):self.world = Atlas()
  greek_world = World()#module named Greek_gods
  import world
  class Zeus(object):def __init__(self):self.world = world.greek_world
  

I would recommend to use the second solution; after that, the first one. The third one, however, can be very useful, too, specially if, by default, you need just one world in your application (the so-called singletons).
