data['i']=content

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

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

target = json.loads(html)
target = target['translateResult'][0][0]['tgt']
print(target)
出现的错误是：

请输入带翻译的内容： i
Traceback (most recent call last):
  File "E:\python课后题\54-1.py", line 26, in <module>
    target = target['translateResult'][0][0]['tgt']
KeyError: 'translateResult'

将在审查元素中获得的url中translate后面的_o去掉，错误就消失
