Exactly correct. Assignment is an operation on a namespace using a new
value, and does not involve the former value. Something similar to
assignment overloading is possible with properties, but you need to be
using object attributes, not names in a module (or function locals).
class SomeDemo(object):
def _read_foo(self):
print 'Reading foo'
return self._foo
def _write_foo(self, value):
print 'Writing foo as %r' % value
return self._foo
def _del_foo(self):
print 'Deleting foo'
del self._foo
foo = property(_read_foo, _write_foo, _del_foo)
obj = SomeDemo()
obj.foo = 123
obj.foo += 1
del obj.foo
