level: beginners I was trying to write simple code that compares 2 tuples and returns any element in the second tuple that is not in the first tuple.
def tuples(t1, t2): result = [] for b in t2: for a in t1: if b == a: break else: result=result+[b,] return result print tuples([0,5,6], [0,5,6,3,7]) the code works but i was surprised by the following: my understanding was that an ELSE clause is part of an IF statement. Therefore it comes at the same indentation as the IF statement. However the above example only works if the ELSE clause is positioned under the second FOR loop. As if it was an ELSE clause without an IF statement....!? Why/How does this work? tnx Baba -- http://mail.python.org/mailman/listinfo/python-list
