Python字符串和列表串联错误

Question

这是一个相当初学者的问题，因为我对编码非常陌生……如果您能指导我的话，将会非常感谢您

import time
from datetime import datetime as dt

host_file = r"C:\Windows\System32\drivers\etc\hosts"
host_temp = "hosts"
redirect = "127.0.0.1"
website_list=['facebook.com','www.facebook.com']

while True:
    if dt(dt.now().year,dt.now().month,dt.now().day,8) < dt.now() < dt(dt.now().year,dt.now().month,dt.now().day,18):
        print("working hours .....")
        with open(host_temp , "r+") as file:
            content = file.read()
            for web in website_list:
                if web in content:
                    pass
                else:
                    file.write(redirect+website_list)
    else:
        print("fun hours .....")
    time.sleep(5)
