Next we just need to restructure the data into a useful format, in this case we'll put collect the strings together and then dump it as json format.

By using json it is ready for more advanced manipulations in the future. Further atomization of the data is possible too, but sticking with our original plan is a good example to begin with.

Remember the two levels of data we want to collect: host level and service/port level, stored in the following as host_state and port_state.

import nmap, json, time

def scan(host='127.0.0.1',range='22-80'):
  '''Setup port scanner'''
  nm = nmap.PortScanner()
  nm.scan(host, range)
  return nm

nm = scan()

for host in nm.all_hosts():
  host_state = {}
  host_state["host"] = host
  host_state["state"] = nm[host].state()
  for proto in nm[host].all_protocols():
    for port in nm[host][proto].keys():
      port_state = nm[host][proto][port]
      port_state["host"] = host
      port_state["protocol"] = proto
      port_state["port"] = port
      timestamp = time.time()
      host_state["timestamp"] = str(timestamp)
      port_state["timestamp"] = str(timestamp)
      print json.dumps(host_state)
      print json.dumps(port_state)
      docid = str(host) + ":" + str(proto) + ":" + str(port) + ":" + str(port_state["timestamp"])

In addition to a few more lines of code, note specifically that you must now import json and time modules. We also remove all the verbose print lines and only print the resulting json string instead. The docid variable is also created, which will be used for the Couchbase document key in the next step.
