Code failed JSON KeyError

[popps]

Hello,

I am trying to retrieve information on network equipment, but I have the following error and I do not know how to handle it

Error:
connect : xxxxx
{"device": "switch_1", "interface": "Ethernet1/1", "description": "xxxxxx"}
{"device": "switch_1", "interface": "Ethernet1/2", "description": "xxxxxx"}
{"device": "switch_1", "interface": "Ethernet1/3", "description": "xxxxxx"}
Traceback (most recent call last):
  File "test_mac_inv.py", line 51, in <module>
    desc = items["desc"]
KeyError: 'desc'

I know where this error came from. At times I don't have the description information.
How can I make the code go to the next JSON line and not do the KeyError?

Thank's
My code

 IP =  ["xxx.xxx.xxx.xxx"]
 #SSH INIT
 ssh = paramiko.SSHClient()
 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

 username = "xxxxxx"
 password = "xxxxxxx"
 port = 22

 for swi in IP:
         Connection = "connect : " + swi
         print Connection
 #GET hostname
         ssh.connect(swi, port, username, password, look_for_keys=False)
         stdin,stdout,stderr = ssh.exec_command('show hostname ')
         host = str(stdout.readlines()[0].strip())
 #GET desc
         ssh.connect(swi, port, username, password, look_for_keys=False)
         stdin,stdout,stderr = ssh.exec_command('show interface description | json ')
         output = stdout.readlines()

         #GET OUTPUT
         JSON_DATA = json.loads('\n'.join(output))

         for items in JSON_DATA["TABLE_interface"]["ROW_interface"]:
              interface = items["interface"]
              desc = items["desc"]
              Cisco_Inventory = { "device" : host, "interface" : str(items["interface"]), "description" : str(items["desc"])}
              print Cisco_Inventory
