I've almost never had to use (x)range in a for loop. Usually, one just iterate over an iterable.

The main idea here is to encapsulate the knowledge about how iteration is implemented, so the client code just have to iterate. > or, > > for (i = 0 ; i < 10 ; i++) > i = 10; for i in range(10): i = 10 What's your point, exactly ? > > I don't think range/xrange sucks, but I really think there should be > some other constructs to improve the looping flexibility. Have a look at generators then. -- http://mail.python.org/mailman/listinfo/python-list
