# Variables
host = ('169.254.255.64', '57400')

# Body
if __name__ == '__main__':
    with gNMIclient(target=host, username='admin', password='admin', insecure=True) as gc:
         result = gc.get(path=['openconfig-interfaces:interfaces', 'openconfig-acl:acl'])

    print(result)

All gNMI RPCs supported
