Mark attribute as read-only

[Florian Lindner]

Hello,
how can I mark a attribute of a class as read-only (for non classmembers)?
Yes, stupid question, but the docu gave me no help.

Thanks,

Florian

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
