Can you remember how to do this?

 >>> help(isinstance)
Help on built-in function isinstance in module builtins:

isinstance(obj, class_or_tuple, /)
     Return whether an object is an instance of a class or of a subclass 

     A tuple, as in ``isinstance(x, (A, B, ...))``, may be given as the 
target to check against. This is equivalent to ``isinstance(x, A) or 
isinstance(x, B) or ...`` etc.

Or do you need help :)

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
