我在运行完美的python3中编写了以下代码：
now = datetime.now()
current_time = now.strftime("%H:%M:%S")
message = ""
run_again = False
try:
response = requests.get(url, headers=headers, cookies=cookies, allow_redirects=False)
except requests.exceptions.RequestException as e:
message = "Connection Failed!"
run_again = True
if "משתמש לא מזוהה" in response.text:
message = "User Was Logged Out Automatically!"
但是，当我断开互联网连接时，会出现以下错误：
if "משתמש לא מזוהה" in response.text:
UnboundLocalError: local variable 'response' referenced before assignment
我该如何解决？
如果没有互联网，这条线上将引发例外情况。
response = requests.get(url, headers=headers, cookies=cookies, allow_redirects=False)
那将是response不确定的。解决此问题的一种方法是将if语句移至try块
try:
response = requests.get(url, headers=headers, cookies=cookies, allow_redirects=False)
if "משתמש לא מזוהה" in response.text:
message = "User Was Logged Out Automatically!"
except requests.exceptions.RequestException as e:
message = "Connection Failed!"
run_again = True
