This code helps me make an ssh connection. I know that set_missing_host_key_policy helps when the key is not found in the known_hosts. But it is not behaving like the actual ssh, because after the first time I run this code, I assumed that that the host_key would be added to known_hosts and that I need not have the function set_missing_host_key_policy() anymore. But, I was wrong (paramiko.ssh_exception.SSHException). How can I permanently add the host_key to known_hosts using paramiko? (As a certain part of the backend code is written in 'C' and it needs the host_key to be found in known_hosts)

Or am I misunderstanding something? I would need some guidance on this...

import paramiko

client = paramiko.SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname=str(host),username =str(user),password=str(pswd))
