In python:

Is there a way to check for an instance (any instance) of a specific class in a list?

Thank you,

 for element in thelist:
 if isinstance(element, TheClass):
 print 'found an instance'

The usual warnings apply; you shouldn't typically have to care about the exact type of an object, only the behaviours it supports. Consider your design carefully.

Thank you, that is a bit more complicated than I would have liked but I'm not really surprised about that.
