Declare it as such in the documentation. ;)
If you want to provide error messages, you could alternatively define a
property:
py> class C(object):
... def _getx(self):
... return self._x
... x = property(fget=_getx)
... def __init__(self, x):
... self._x = x
...
py> c = C(4)
py> c.x
4
py> c.x = 6
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
AttributeError: can't set attribute
