Crawler crawls a website and can't run with the following code! There seems to be a problem with the regularity. Please give me the correct regularity of a mailbox. Thank you.

  
    mkt@all-dream.com 
   response=requests.get("http://www.doyd.cn/")
    if re.findall("""[\w!-sharp$%&"*+/=?^_`{|}~-]+(?:\.[\w!-sharp$%&"*+/=?^_`{|}~-]+)*@(?:[\w](?:[\w-]*[\w])?\.)+[\w](?:[\w-]*[\w])?""",response.text):
        print("email")
        item["email"]=re.findall("""[\w!-sharp$%&"*+/=?^_`{|}~-]+(?:\.[\w!-sharp$%&"*+/=?^_`{|}~-]+)*@(?:[\w](?:[\w-]*[\w])?\.)+[\w](?:[\w-]*[\w])?""",response.text)[0]
    else:
        print("no email")
        print("")
        item["email"] = ""

when I was running the website in bulk, when I climbed to this website, I got stuck and asked for advice. Why didn"t the card owner move?
because it is a regular matching mailbox, all the other websites have run out before, so this one is stuck!
