Beginner question? Classes, variables, ...

[Ángel Gutiérrez Rodríguez]

The problem:

I have two classes:
 
class X:
  def __init__(self):
    pass

class Y:
  def __init__(self):
    self.a=1
    self.b=X()

and I would like to make 'a' visible inside 'x'. Is there a way to refer to
the Y class from the X? To make things easier :), each class is in a
different file, so class X is imported. Or the only way I have is to
pass 'a' as a variable in each method call of 'b' ('a' can take different
values that affect to the behaviour of 'b').

Thanks in advance.
