有两个问题
1.百度翻译的URL有变化，没有后面的q
2. userinput 不要加引号

下面是可能使用的代码

 #!/usr/bin/env python                                                                                            
 # coding=utf-8   

import requests
userinput = input("请输入想要翻译的单词: ")
data = {"from":"en","to":"zh","query":userinput,"transtype":"realtime","simple_means_flag":"3"}

r = requests.post("http://fanyi.baidu.com/v2transapi", data)
print(r.json()["trans_result"]["data"][0]["dst"])
