I am trying to calculate the % slope of multiple polylines in a shapefile. I am using Arc 10.1 with the basic licence.


When I run my code in the Field Calculator I get a Python syntax error on line 3. I can't see the issue - can someone tell me where I'm going wrong?


My code is:


NB - I am not sure what directions the polylines were digitised in. Hence I don't know if the last point is at the higher elevation or vice versa, which is why I am trying to return the absolute change in z value.


The error read out I am getting when I run the code is:


Thanks in advance!
