You may receive PermissionError: [WinError 5] Access is denied: ‘C:\\Windows\\to_your_path’ while you use shutil.rmtree python code in windows environment.
shutil.rmtree is utility with a function that can remove directory in windows even if it contains files or subdirectories.
But what happens when you encounter WinError 5?
It may be while you use explorer.exe to enter the directory you want to delete and go back to the parent folder in some cases.So, it may be explorer.exe occupy the directory handles while you use explorer to check it and go back and run the python script.
Solution: Just close the explorer window which contains the history of the directory you want to remove.

If I have a python script in linux, touch run.sh:
#!/bin/bash
python3 script_name.py

chmod +x run.sh

I want to divide wan_net,lan_net and iptv net in the home ethernet. 2 switches are response to divide vlan, which are tl-sg2016d and tl-sg2008d.

I always use 1 cable cat-6 line of port 1 for single line multiplexing. Port 1 is responsible for the transmission of 3 VLAN. Port 2 is responsible for wan_lan. Port 3 is responsible for iptv. Port 4 and all the remaining ports are responsible for lan network.

1.set 802.1Q VLAN of switches

1.1 set tl-sg2016d

Set wan_net, lan_net, iptv of tl-sg2016d respectively. like pic 1.

1.2 set tl-sg2008d

Set wan_net, lan_net, iptv of tl-sg2008d respectively. like pic 2.

2.modified 802.1Q VLAN PVID to assign vlan tag

2.1 set tl-sg2016d

Assign port 4-16 as VLAN 3(lan_net).Assign port 2 as VLAN 2(wan_net).Assign port 3 as VLAN 4(iptv).Assign port 1 as VLAN 1(default).

2.2 set tl-sg2008d

Assign port 4-8 as VLAN 3(lan_net).Assign port 2 as VLAN 2(wan_net).Assign port 3 as VLAN 4(iptv).Assign port 1 as VLAN 1(default).

3. Other thing about ip address

You can assign a lan_net ip address and gateway to switch to replace ip 10.18.18.251 to manage it in the local network.
