            print("Start Blocking..")
            ***with open(host_path,"r ") as host_file:***
                content = host_file.read()
                for website in site_block:
                    if website not in content:

PermissionError: [Errno 13] Permission denied: 'C:/Windows/System32/drivers/etc/hosts'

CodePudding user response：

Permission denied simply means the system is not having permission to open the file to that folder.

C:\Windows\System32\drivers\etc\hosts is writable only by the Administrator. You should run your script in Administrator mode.

CodePudding user response：

The PermissionError is caused when you do not have a permission to do something. The file C:/Windows/System32/drivers/etc/hosts is protected by the permission. That is why you cannot access to it. Why don't you run it as administrator?
