 Let's continue with the dataset of daily-averaged discharge the Rhine you used at {ref}`EXERCISE-1.4`. Create again a new _.py_ file called _Exercise6_ in your work-directory, where you load _LobithDischargeData.asc_ and the commands needed to solve the following assignments.
 
 ### Morphologically relevant statistics of the discharge dataset
