Relative Field Values in For Loop

TomGiles — Thu, 15 Mar 2012 20:45:41 GMT

My issue is trying to retrieve field values inside a for loop:

#userFile - type FeatureLayer
userFile = arcpy.GetParameterAsText(0)

#user selects field from userFile - type Field "obtained from [userFile]"
userField = arcpy.GetParameterAsText(1)

#start cursor
rows = = arcpy.SearchCursor(userFile)

#inside loop, report all values of field [userField]
for row in rows:
        arcpy.AddMessage("Analyzing zone " + row.userField)

Python wants userField to be a hard coded value for the field. It won't accept it as a variable set by the user. Any way I can accomplish this?

Cheers
Tom

Thanks Mathew - I knew it was too easy.

Also Tom, you have == in the searchcursor line which won't work ... which I see you have now fixed
