Netmiko python script to add a new ip address to a blacklist group on multiple Cisco ASA firewalls

add-to-asa-blacklist.py

#!/usr/bin/env python3

#check that we have enough parameters to continue (the ip addresses we need)

hi can you please tell me where i have to put the IP address , which i have to block

At Line no .19 = param_1 = sys.argv[1], probably.
