I'm not sure if I know what you mean. Basically, I want to know how to
write that depends on the read's response. For example,
import getpass
import sys
import telnetlib
HOST = "localhost"
user = raw_input("Enter your remote account: ")
password = getpass.getpass()
tn = telnetlib.Telnet(HOST)
tn.read_until("login: ")
tn.write(user + "\n")
if password:
tn.read_until("Password: ")
tn.write(password + "\n")
tn.write("ls\n")
tn.write("exit\n")
print tn.read_all()
This example only assumes tn.read_until() will read "Password". What if the
tn returns something else? Therefore, I want to check the "Password"
returns before I write password.
