Slicing took that "step" argument since 1.4. However, only Numeric arrays used it up until 2.3 where it was added to the builtin types. > 2.

Since I've obviously been living in ignorance all these years! http://www.python.org/doc/2.3.5/whatsnew/section-slices.html Generally the "What's New" documents are very good for catching up. I've found that they're also a very good, high-density method of refreshing one's memory about useful little tidbits. Sadly, they're not all collected in one place for that purpose. But you can fake it a bit by replacing <version> in the following URL with each of 2.2.3, 2.3.5, 2.4.3, 2.5: http://www.python.org/doc/<version>/whatsnew/ -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
