How can I insert non-duplicate data in a list? I mean, is there a particular option in the creation of a list that permit me not to use something like:def append_unique(l, val): if val not in l: l.append(val)Thanks, Mattia
Unless the insertion order is important, you could use a set -- where a second insertion will have no effect.
>>> s = set() >>> s.add(1) >>> s.add(2) >>> s.add(1) >>> print s set([1, 2]) Gary Herron -- http://mail.python.org/mailman/listinfo/python-list
