arr1 = [ 'a', 'b', 'c', 1, 2, 3 ] # populate a new list with individual members arr2 = [ arr1[0], arr1[3], arr1[5] ] # create a new list by adding slices together arr3 = arr1[:1] + arr1[2:4] + arr1[5:] print arr2 # output is: ['a', 1, 3] print arr3 # output is: ['a', 'c', 1, 3] -- Denis McMahon, denismfmcma...@gmail.com -- http://mail.python.org/mailman/listinfo/python-list
