the codes as follow:
class Base:
def fun(self):
print "base_fun"
def fun2(self):
print "base_fun2"
class Foo:
def __init__(self, base):
self.__base = base
def fun3(self):
print "foo_fun3"
b = Base()
foo = Foo(b)
my aim is:when "foo.fun3()" be called,it run as usually, but when
"foo.fun()" or "foo.fun2() be called, as Foo hasn't attribute "fun()" and
"fun2()", foo will call "self.__base.fun()" or "self.__base.fun2()".
when a attr can't be find in foo, it's will try to search 'self.__base". I
think this maybe need to use "__getattr__" and "__setattr__" ,but I cant do
it successfully. can someone help me?
