Change IP using Python

[sathish 0]

Hi, Everyone is there any possible way to change the IP address of tinker board using python script. I tried to change it using script, changes reflecting in network file properly (/etc/NetworkManager/system-connections/Wired Ethernet1.nmconnection). But It's creating new connection eth0  and taking auto IP. Not taking my IP, anyone have any idea about this my guess is because of edit maybe format change will happens because of that its not changing I think.  File also attached . 

Eg.

[connection]
id=Ethernet connection 1
uuid=940351fd-af24-4694-ab43-65f8560e76d7
type=ethernet
permissions=

[ethernet]
mac-address-blacklist=

[ipv4]
address1= 192.168.1.220/24,192.168.1.10
dns8.8.8.8 4.2.2.2
dns-search=
method=manual

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
ip6-privacy=0
method=auto

Wired1.nmconnection

import netifaces
from configobj import ConfigObj

def change_ip_address(interface_name, new_ip, new_subnet, new_gateway):
    iface = netifaces.ifaddresses(interface_name)
    current_ip = iface[netifaces.AF_INET][0]['addr']
    current_subnet = iface[netifaces.AF_INET][0]['netmask']

    config = ConfigObj('/etc/NetworkManager/system-connections/Wired Ethernet1.nmconnection', encoding='utf8')
    config['ipv4']['address1'] = f"{new_ip}/{new_subnet}"
    config['ipv4']['gateway'] = new_gateway
    config.write()

    print(f"IP address for {interface_name} changed from {current_ip}/{current_subnet} to {new_ip}/{new_subnet}")

interface_name = 'eth0'
new_ip = '192.168.1.220'
new_subnet = '24'
new_gateway = '192.168.1.1'

change_ip_address(interface_name, new_ip, new_subnet, new_gateway)
