I suspect this is off-topic for python-dev, and would be better on
comp.lang.python or similar, but for what it's worth, I consider having
an attribute named 'None' bad practise, regardless of any runtime
checks. But as part of Python's "we're all consenting adults here"
philosophy, I wouldn't approve of expensive or extensive run-time
checks specifically to prevent it. If you really have to name your
attribute None, and are prepared to live with the consequences, then go
ahead.
In a similar fashion:
>>> class Parrot(object):
... pass
...
>>> p = Parrot()
>>> p.1 = 'spam'
File "<stdin>", line 1
p.1
^
SyntaxError: invalid syntax
>>> setattr(p, '1', 'spam')
>>>
