Offhand, my only quibble is that sys.exit is not helpful for debugging.
Much better to raise an error:
if not self.funcTable.get(attribute, lambda x: True)(value):
raise ValueError ('error out of bound')
or define a subclass of ValueError just for this purpose. On error, the
program will stop just as dead, but you'll get a trace.
