我知道关于同一个问题有很多问题,但我没有找到解决我问题的答案
我做了一个应用程序,写在主机文件的某些字,但当我来输出程序,它显示关闭的文件 这是我的密码
import time
from datetime import datetime as dt
host_temp = r"C:\Users\ALAA\AppData\Local\atom\app-1.38.2\hello\web site blocker\hosts"
host_path = r"C:\Windows\System32\drivers\etc\hosts"
redirect = "127.0.0.1"
website_list = ["www.facebook.com","www.instagram.com", "www.youtube.com"]
while True:
if dt(dt.now().year,dt.now().month,dt.now().day,16) < dt.now() < dt(dt.now().year,dt.now().month,dt.now().day,23):
print("Working hours!!!")
with open(host_temp, "r+") as file:
content = file.read()
for website in website_list:
if website in content:
pass
else:
file.write(redirect + " " + website + "\n")
else:
print("Fun hours!!!")
time.sleep(5)
这里是错误信息
Working hours!!!
Traceback (most recent call last):
File "C:\Users\ALAA\AppData\Local\atom\app-1.38.2\hello\web site blocker\web_site_blocker.py", line 20, in <module>
file.write(redirect + " " + website + "\n")
ValueError: I/O operation on closed file.
试试这个:
我缩进了for循环及其内容,因为python不会忽略不正确的缩进
