I am trying to run the select attribute tool for a layer that I created. I can manually run the tool in ArcMap, but when I write the script the code fails after the copy feature tool was used. Not sure what I am doing wrong, I am using the ArcMap help section to get a general idea of the code that I needed.
I am new to python, so I appreciate any guidance anyone has:
#Import a CSV file that will show you what ASOS weather stations are in the state.
