利用python写一个有道翻译的脚本

import urllib.request
import urllib.parse
import json
content = input("请输入要翻译的内容：")
url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule&smartresult=ugc&sessionFrom=null'
data = {}
data['type'] = 'AUTO'
data['i'] = content
data['doctype'] = 'json'
data['xmlVersion'] = '1.8'
data['keyfrom'] = 'fanyi.web'
data['ue'] = 'UTF-8'
data['action'] = 'FY_BY_CLICKBUTTON'
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("翻译结果：%s" % (target['translateResult'][0][0]['tgt']))

import urllib.request
url = "http://img1.mm131.com/pic/2537/"
for i in range(1,50,1):
page_url = url + str(i) + '.jpg'
response = urllib.request.urlopen(page_url)
cat_img = response.read()
filename = page_url.split('/')[-1]
with open(filename,'wb') as f:
f.write(cat_img)
