关于#Python，运行报错求专家解答。

为什么我加上heabers就报错
代码：
import requests

start_url = "http://www.baidu.com/%22
heabers = {
"User-Agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36"
}

response = requests.get(url=start_url,heabers=heabers)
print(response)

运行结果
报错：
TypeError: request() got an unexpected keyword argument 'heabers'

heabers=heabers

headers=heabers
