6.访问有道词典查询单词

import urllib.request
import urllib.parse

url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule'
data = {}
data['i'] = 'I love you'
data['type'] = 'AUTO'
data['doctype'] = 'json'
data['version'] = '2.1'
data['keyfrom'] = 'fanyi.web'
data['typoResult'] = 'true'

data = urllib.parse.urlencode(data).encode('utf-8')

response = urllib.request.urlopen(url,data)

html = response.read().decode('utf-8')

print(html)

7.结果json数据

{"type":"EN2ZH_CN","errorCode":0,"elapsedTime":1,"translateResult":[[{"src":"I love you","tgt":"我爱你"}]]}

8.处理查询的数据，将json转化为字典

import json
target =  json.loads(html)
{'type': 'EN2ZH_CN', 'errorCode': 0, 'elapsedTime': 1, 'translateResult': [[{'src': 'I love you', 'tgt': '我爱你'}]]}

9.获取翻译的数据

target['translateResult'][0][0]['tgt']

10.有道词典

import urllib.request
import urllib.parse
import json

while True:
    text = input('请输入要翻译的文字:')
    if text == 'exit':
        break

    url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule'
    data = {}
    data['i'] = text
    data['type'] = 'AUTO'
    data['doctype'] = 'json'
    data['version'] = '2.1'
    data['keyfrom'] = 'fanyi.web'
    data['typoResult'] = 'true'

    data = urllib.parse.urlencode(data).encode('utf-8')

    response = urllib.request.urlopen(url,data)

    html = response.read().decode('utf-8')

    target = json.loads(html)

    print(target['translateResult'][0][0]['tgt'])
    print('输入exit退出程序！')

'我爱你'
