So far I have searched for info on how to pass variables from one class

Remember that OOP is about creating objects from classes.
You can pass an object to another rather than just the
variables, in fact its preferable!
Also remember that you can create many objects from one class.
So just because you have one Room class doesn't mean you are
stuck with one room object. You can have many and each can
be connected to another.
You can get rooms to describe themselves, you can enter a room.
You might even be able to create new rooms or destroy existing ones.
These actions can all be methods of your Room class.
Here is an example somewhat like yours that passes objects:
class Printer:
def __init__(self,number=0):
self.value = number
def sayIt(self):
print self.value
class MyApp:
def __init__(self, aPrinter = None):
if aPrinter == None: # if no object passed create one
aPrinter = Printer()
self.obj = aPrinter # assign object
def doIt()
self.obj.sayIt() # use object
def test()
p = Printer(42)
a1 MyApp()
a2 = MyApp(p) # pass p object into a2
a1.doIt() # prints default value = 0
a2.doIt() # prints 42, the value of p
test()
