Batch Add Fields, Model Builder

Hi All,

Can anyone suggest a better way to batch add fields using the model builder? See attached image.

Thanks,

My first thought is to use Python and arcpy.AddField_management(). This assumes all the fields are the same type and length. If they are all different, it can still be done but the code would have to be changed a bit.

import arcpy

testtable = r"C:\temp\mygdb.gdb\Test"

newfields = [
    "Test1",
    "Test2",
    "Test3",
    "Test4",
    "Test5"
]

for field in newfields:
    arcpy.AddField_management(
        testtable,  ## in_table
        field,  ## field_name
        "TEXT",  ## field_type
    )
    print "{} added".format(field)
