[Python-Dev] Assignment to None (original) (raw)

So, it's okay to setattr the attribute name "None" but not okay to set it directly? Is this deliberate or is it an unintentional side effect of parser changes to prevent assignment to None?

It's deliberate. setattr(o, "foo bar", "baz") also works, even though "foo bar" is not an identifier. setattr doesn't take the Python grammar into account, but only the object's structure.

Regards, Martin
