f = open("C:\\Users\0\Desktop\\deneme.txt")
for line in f:
ip_address = line.strip()
ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(hostname=ip_address, username=username, password=password)
f.close()
print ("Successfull", ip_address)
