            ]
          }
        }
      ]
    }
  ]
}

所以我试着提取字段“txid:”、“value:”和“addresses:”的值，我可以提取字段txid和value，但是提取addresses字段失败，我就是无法到达addresses字段。这是我用python编写的代码

jdata = json.loads(open('rawtrans.json').read())

for x in range(0,2):
for c in jdata['tx']:
    print 'txid: {}'.format(c.get('txid'))

for c in jdata['tx'][x]['vout']:
    print 'value: {}'.format(c.get('value'))

for c in jdata['tx']['vout'][x]['scriptPubKey']:
    print 'addresses: {}'.format(c.get('addresses'))
