I'm trying to implement a simple repeateable property mechansism so I
don't have to write accessors for every single instance variable I have.
------------
classMyObject:
def __init__ (self):
self.initialize()
def initialize(self):
self._value=None
def _setProperty (self, name, value):
print "set property"
setattr (self, name, value)
def _getProperty (self, name):
print "get property"
return getattr (self, name)
#properties
value = property (lambda self: self._getProperty("_value"),
lambda self, value: self._setProperty("_value",
value))
def testObject():
o = MyObject()
print o.__dict__
print o.value
o.value = 123
print o.value
print o.__dict__
if __name__ == "__main__":
testObject()
---------
The outout looks like this
------------
{'_value': None}
get property
None
123
{'_value': None, 'value': 123}
-----------
As you can see, the _getProperty() method gets called properly when I do
'o.value' but 'o.value = 123' does not seem to use the property
stucture. I can't figure out why 'o.value=123' does not call
_setProperty()
Any ideas?
