pycharm中出现NameError: name 'response' is not defined

import requests
if name == "main":
url = "https://www.sogou.com/web?query=%E6%B3%A2%E6%99%93%E5%BC%A0%22
kw = input('enter a word:')
param = {
'query': kw
}
requests.get(url=url, params=param)
page_text = response.text
fileName = kw+".html"
with open(fileName, "w", encoding='utf-8') as fp:
fp.write(page_text)
print(fileName, '保存成功！')
出现了错误 显示
Traceback (most recent call last):
File "C:/Users/Percy/网络爬虫/网络爬虫.py", line 9, in
page_text = response.text
NameError: name 'response' is not defined

你是不是少写了一句
response=requests.get(url=url, params=param)
