After much experimentation, I found the following solution:
commandString =
"\\xA500046898000AC73D228B0B01800000000000000000000000000000000040003BF9"
insert = "INSERT INTO profile_commands(command_id, profile_id,
execution_order, command, command_type) VALUES(%s, %s, 0, %s, 1); "
self.cur.execute(insert, (command_id, profileID, commandString,))
The 'key' to solving this was to add the \\x to the beginning of commandString.
Thanks to all who pondered this
Stacy
