Here you go:
>>> database = {
... "Alice": 24,
... "Bob":25}
...
>>> class Lookup(object):
... def __catcher(self, name):
... try:
... print "Hello my name is %s and I'm %s" % (name,
database[name])
... except KeyError:
... print "There was an error"
... def __getattr__(self, attr):
... return lambda:self.__catcher(attr)
...
>>> inst = Lookup()
>>> inst.Alice()
Hello my name is Alice and I'm 24
>>> inst.Bob()
Hello my name is Bob and I'm 25
>>> inst.John()
There was an error
>>>
