Answer 1

Can you try as follows:

from napalm import get_network_driver
from getpass import getpass
 
 
hostname = input("IP address of router: ")
username = input(f"Username of {hostname}: ")
password = getpass(f"Password of {hostname}")
secret = getpass(f"Enable password of {hostname}: ")
 
driver = get_network_driver("ios")
device_detail = {
    "hostname": hostname,
    "username": username,
    "password": password,
    "optional_args": {
        "secret": secret
    }
}
 
with driver(**device_detail) as router:
    print(router.get_facts())
