Thank for your type about the syntax error. This an example example, the keys of my dictionary are tuples: d = {(37.75, 42.22): 1 , (37.51, 40.02): 3 (45.55, 24.27): 4 (47.08, 30.99) : 1} But what I will is to get all keys which has the same valus. And not the keys that have value more than 1! Nader -- http://mail.python.org/mailman/listinfo/python-list
