Table properties example
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
