拒绝访问“ C：\ Windows \ System32 \ Drivers \ etc \ hosts”的权限

Question

所以尝试以管理员身份运行此python代码时遇到问题，因此我无法访问主机文件并在主机文件上写入。谁能帮我？我浏览了许多其他问题，但似乎没有一个起作用。

主机文件目录： C：\ Windows \ System32 \ Drivers \ etc \ hosts

（例如） Request UAC elevation from within a Python script?

其中一些答案实际上在提示获得管理员访问权限时起作用，但仍未授予我的程序许可。我发现的唯一方法是先以管理员身份运行python shell，然后以管理员身份运行代码或运行命令提示符，然后使用命令提示符打开python文件。

网站

该程序是用于阻止网站的。

import time 
from datetime import datetime as dt 

# change hosts path according to your OS 
hosts_path = r”C:\Windows\System32\Drivers\etc\hosts”
# localhost's IP 
redirect = "127.0.0.1"

# websites That you want to block 
website_list = ["www.facebook.com","facebook.com", 
      "dub119.mail.live.com","www.dub119.mail.live.com", 
      "www.gmail.com","gmail.com"] 

while True: 

    # time of your work 
    if dt(dt.now().year, dt.now().month, dt.now().day,8)  < dt.now() < dt(dt.now().year, dt.now().month, dt.now().day,16): 
        print("Working hours...") 
        with open(hosts_path, 'r+') as file: 
            content = file.read() 
            for website in website_list: 
                if website in content: 
                    pass
                else: 
                    # mapping hostnames to your localhost IP address 
                    file.write(redirect + " " + website + "\n") 
    else: 
        with open(hosts_path, 'r+') as file: 
            content=file.readlines() 
            file.seek(0) 
            for line in content: 
                if not any(website in line for website in website_list): 
                    file.write(line) 

            # removing hostnmes from host file 
            file.truncate() 

        print("Fun hours...") 
    time.sleep(5) 

这是错误：

Working hours...
Traceback (most recent call last):
  File "C:\Users\Key\Desktop\random project.py", line 19, in <module>
    with open(hosts_path, 'r+') as file:
PermissionError: [Errno 13] Permission denied: 'C:\\Windows\\System32\\Drivers\\etc\\hosts'

您可以在this link之后为程序运行所在的用户添加写权限，以向主机文件添加权限
