Awesome, Thomas. The trick only works if there is only *one* leading
underscore in the *method* names.
The following example works as I expected for the derived class B.
class A(object):
def __init__(self):
self.__not_here = 1
def _get_not_here(self):
return self.__not_here
def _set_not_here(self, v):
print "I am called"
self.__not_here = v
not_here = property(lambda self: self._get_not_here(), lambda self, v:
self._set_not_here(v))
class B(A):
def _set_not_here(self, v):
print "version B"
self.__not_here = v
a = A()
# print a.__not_here
print a.not_here
# a.set_not_here(10)
a.not_here = 10
print a.not_here
b = B()
print b.not_here
b.not_here = 70 # print version B
print b.not_here
