这个sug url只能翻译单个字,翻译有另外的url:https://fanyi.baidu.com/v2transapi,且还需要提交sign和token,你可以参考下这个:https://blog.csdn.net/qq_38534107/article/details/90440403,以下是参考他的方法写的代码:

会不会是哪里出问题了?如果你只需要英翻中,可以试试直接get,我的浏览器显示的这样的url
https://fanyi.baidu.com/?aldtype=16047#en/zh/cat
看见没有,这个就很明显了
temp = input('请输入待翻译的英文:')
url = r'https://fanyi.baidu.com/?aldtype=16047#en/zh/'+temp
