I'm trying to learn how to create Script Tools in ArcGIS Pro, so I thought I would start small with a tutorial on https://www.e-education.psu.edu/geog485/node/120
The tutorial has you make a simple buffer tool, but whenever I check the module it says invalid syntax.
Here is my script and the error message. I know that it is identifying "arcpy" on the last line as the problem. I just don't know why.
