Can't refer to base class attribute?

I've got a Base class with an attribute "foo" (of type Foo), and a
Derived class (derived from Base). In Derived's constructor, I try to
refer to Base.foo, but python complains:
AttributeError: class Base has no attribute 'foo'

Any ideas? (code below)

=== CODE ===
#!/usr/bin/python

class Foo:
def __init__ (self):
self.x = 3

class Base:
def __init__ (self):
self.foo = Foo()

class Derived(Base):
def __init__(self):
Base.__init__(self)
Base.foo.x = 5

Derived()
=== EOF ===
