In case you want to due numerical calculations take a look at numpy it has an extended slicing notation to select columns directly. See http://www.scipy.org # create 10x10 numpy array filled with 1 data = numpy.ones((10,10)) column = data[:,0] Best wishes! Bernhard -- http://mail.python.org/mailman/listinfo/python-list
