请教这句代码哪错了？？

rt=requests.get("https://baike.baidu.com/item/Python/407313") #这句执行错误，没想明白为什么

rt=requests.get("https://baike.sogou.com/v58828.htm?fromTitle=Python") #这一句可以执行，为什么上一句出错？

Start by reproducing the two requests shown in the issue and read the traceback through requests/api.py and requests/sessions.py, especially the redirect handling. The issue would need a confirmed project change or a documented explanation of why the Baidu URL redirects repeatedly while the Sogou URL succeeds.
