You should probably look at the wealth of information at http://www.python.org/doc - the tutorial is a good start on how to use the language, and the library reference has much more depth on the array module. http://docs.python.org/lib/module-array.html -- Sean Blakey Saint of Mild Amusement, Evil Genius, Big Geek Python/Java/C++/C(Unix/Windows/Palm/Web) developer quine = ['print "quine =",quine,"; exec(quine[0])"'] ; exec(quine[0]) -- http://mail.python.org/mailman/listinfo/python-list
