import socket
import ssl
from datetime import datetime


def get_ssl_expiry_date(host):
    context = ssl.create_default_context()
    with context.wrap_socket(socket.socket(), server_hostname=host) as s:
        s.connect((host, 443))
        cert = s.getpeercert()
    return datetime.strptime(cert['notAfter'], '%b %d %H:%M:%S %Y %Z')


host = 'www.baidu.com'
print(get_ssl_expiry_date(host))
