Dear Gary, thank you for the reply. I will be more specific and take the same example that you have given and tell you what is my problem - array([0.0, 1.3, 2.45, 3.87, 4.54, 5.11, 6.90, 7.78, 8.23, 9.01]) from this array I want to a sub-list with lower and upper indexes that are not present in the above array for example - sub-list[3, 8] Is there a function for this? thank you niranjan
