Python爬虫 headers出错
报错代码：
import requests
url = "https://movie.douban.com/top250"
headers = {'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36'}
res = requests.get(url,headers=headers)
print (res)
答：headers是个字典，要加上键名：“User-Agent”
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36'}
