data = [{'type':'trigger','addr':'0x1234','data':'0x1234'}]
print "data:", data
json_str = json.dumps(data)
print "json:", json_str


輸出結果：
data: [{'data': '0x1234', 'type': 'trigger', 'addr': '0x1234'}]
json: [{"data": "0x1234", "type": "trigger", "addr": "0x1234"}]
 

#!/usr/bin/env python
import json


s = json.loads('{"type":"trigger","addr":"0x1234","data":"0x5678"}')
print s
print s["type"]
print s["addr"]
print s["data"]

輸出結果
