I infer from your example that you want
to set default attributes for *instances of* class pipo
(not for class pipo itself).

Use setattr:

class pipo(object):
    PIPODEFAULTS = {'caseSensitivity':'preserve',
        'cellMapTable':'checkPolygon', # etc
    }
    def __init__(self, *args, **kwargs):
        for attr, value in pipo.PIPODEFAULTS.iteritems():
            setattr(self, attr, value)

a = pipo()
b = pipo()
print a.caseSensitivity
a.caseSensitivity = 'lower'
print a.caseSensitivity
print b.caseSensitivity
