在我这台电脑上始终报错,同样的代码在我同学那里就可以正常输出翻译内容

我运行你的代码也正常输出，没有报错。是不是requests版本不同导致的？
不行的话，你把headers加个host试试：
header = {'User-Agent': 'Mozilla/5.0', 'host': 'fanyi.baidu.com'}

加了host还是不行，应该不是requests版本的问题，今天中午12点才刚装的，会不会和python版本有关？我的是3.8的

这个其实跟选用的python版本的关系不大，主要原因是因为每次使用 pip install 命令下载插件的时候，下载的都是最新的版本，比如下载requests插件，它会自动的将依赖的urllib3这个插件也安装，然后依赖的插件版本太高，就导致了这个报错的问题。---搬运至CSDN,原文链接如下：
