class SOFileIndexRecord(object): def __init__(self, so): self._so=so
def _get_code(self): return self._so.code def _set_code(self, value): self._so.code=value testCode=property(_get_code, _set_code) # What does this do? It says that testCode is a property of SOFileIndexRecord A property looks like a data attribute from the user of the class's point of view but internallty it is accessed via the get/set methods. Thus I can do: s = SOFileIndexRecord(mySo): s.testCode = myCode # actually does s._setCode(myCode) print s.testCode # actually s._getCode() properties allow for creation of read only attributes in Python by having a null set method.(Of course you can still cheat and use the 'hidden' methods, or even the real data attributes. Buit if everyone behaves properly it can help a wee bit.
