request问题-为什么出现这个问题

import urllib.request

req = request.Requst("http://www.baidu.com")

req.add_header("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36")

resp = request.urlopen(req)

print(resp.read().decode("utf-8"))

报错
