Class BigClassA:
def __init__(self):
self.a = 3
def foo(self):
self.b = self.foo1()
self.c = self.foo2()
self.d = self.foo3()
def foo1(self):
# do some work using other methods not listed here
def foo2(self):
# do some work using other methods not listed here
def foo3(self):
# do some work using other methods not listed here
Class BigClassB:
def __init__(self):
self.b = # need value of b from BigClassA
self.c = # need value of c from BigClassA
self.d = # need value of d from BigClassA
def foo(self):
self.f = self.bar()
def bar(self):
# do some work using other methods not listed here and the value of self.b, self.c, and self.d
Class BigClassC:
def __init__(self):
self.b = # need value of b from BigClassA
self.f = # need value of f from BigClassB
def foo(self):
self.g = self.baz()
def baz(self):
# do some work using other methods not listed here and the value of self.b and self.g
Question: Basically I have 3 classes with lots of methods and they are somewhat dependent as you can see from the code. How do I share the value of instance variables self.b, self.c, self.d from BigClassA to BigClassB?
nb: these 3 classes can not be inherited from each other, since it does not make sense.
What I have in mind, is just to combine all methods into a super big class. But I don't feel this is a right way to do it.
You are correct, in your case inheritance does not make sense. But, how about explicitly passing the objects during the instantiation. This would make a lot of sense.
Something like:
Class BigClassA:
def __init__(self):
..
Class BigClassB:
def __init__(self, objA):
self.b = objA.b
self.c = objA.c
self.d = objA.d
Class BigClassC:
def __init__(self, objA, objB):
self.b = objA.b # need value of b from BigClassA
self.f = objB.f # need value of f from BigClassB
While instantiating, do:
objA = BigClassA()
..
objB = BigClassB(objA)
..
objC = BigClassC(objA, objB)
