Python: DeleteField Management_for loop

LarryAdgate — Mon, 02 Feb 2015 16:24:29 GMT

If someone could help me with this, I would forever be greatful. My preference is not to repeat DeleteField_management three times for the three diffrent feature classes, but to use a for loop and loop through all the feature classes except my creation will not work. Please help

Thanks, Larry

# Import arcpy module
import arcpy

# Local variables:
Arden = "C:\\Projects\\TestProject.gdb\\Project\\Arden"
Baypoint = "C:\\Projects\\TestProject.gdb\\Project\\Baypoint"
Clearlake = "C:\\Projects\\TestProject.gdb\\Project\\Clearlake"

mylist = Arden, Baypoint, Clearlake

for delete in mylist:
arcpy.DeleteField_management(mylist, "Pump;Well;Tank")

print "Finished the Delete Function"

It is helpful to post specific error messages, if any, as well.

Try changing your second to last line to:

arcpy.DeleteField_management(delete, ["Pump", "Well", "Tank"])

I believe you're passing the wrong variable to DeleteField_management. You want to pass the current feature class in your loop ("delete"), not the list of feature classes you're looping over.
