I have a variable, f. The value of f might be a list, or it might be a string. I want to do different things to f depending what type it is. How do I check its type from a PythonScript? I can't use type(), as this opens up a security hole with Extension Classes, where the type is the class. I can't import types, as that seems to be restricted. I suggest that either one or both of the following be altered: * The types module is allowed to be imported into restricted stuff. * A safe version of type() is put into the restricted global namespace. I seem to recall a discussion of this a few months ago, where someone (Evan?) proposed a safe version of type(). I guess this got lost in the conversion to RestrictedPython with Zope 2.4. Oh yeah... an ugly workaround is to try to append to f and see if you get and AttributeError. -- Steve Alexander Software Engineer Cat-Box limited
