Beginner question? Classes, variables, ...

[Ángel Gutiérrez RodrÃguez]

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.

You mean the behavior of X here I guess - b is just a name, there isn't much
behavior in it.

Pass X the instance of Y:

class X:
def __init__(self, my_y):
self.my_y

def foo(self):
print self.my_y.a

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

Then in X you can work with whatever Y contains.
