Table properties example (stand-alone script)

The following stand-alone script displays the OID field name if the table has one. It then prints the name and type for each field in the table.

import arcpy

# Create a Describe object from the table.
#
desc = arcpy.Describe("C:/data/chesapeake.gdb/munich")

# If the table has an OID, print the OID field name
#
if desc.hasOID:
    print "OIDFieldName: " + desc.OIDFieldName

# Print the names and types of all the fields in the table
#
for field in desc.fields:
    print "%-22s %s %s" % (field.name, ":", field.type)
    #print field.name + " = " + field.type
