When the output is a feature set or record set, the Result class getOutput() method can be used to return the tool's output in a FeatureSet or RecordSet object. Using the reverse() method we can reverse the contents of the list object in-place i.e., we don’t need to create a new list instead we just copy the existing elements to the original list in reverse order. Python 3 Iterating trough recordset in a list. Access Values in a List. Output: [15, 14, 13, 12, 11, 10] Method 2: Using the reverse() built-in function.
