Please post the actual code that doesn't work. The following works as
expected:

    >>> class A(object):
    ...     def foo(self): return 'Original'
    ...
    >>> a = A()
    >>> b = A()
    >>> a.foo()
    'Original'
    >>> b.foo()
    'Original'
    >>> b.foo = lambda: 'Modified'
    >>> a.foo()
    'Original'
    >>> b.foo()
    'Modified'


HTH,
