Are you using expect only for login purposes? Why don't you use your ssh public key for autologin?

[prodigy_]

set username [lindex $argv 0]
set password [lindex $argv 1]
set hostname [lindex $argv 2]

What's the point of scripting if you enter hostname and credentials manually anyway? You could as well use ssh username@hostname and type your password when prompted.

Or if you call expect from another script, you could use something much simpler like the following stock example from Wikipedia:

spawn ssh $user@machine
while {1} {
  expect {
 
    eof                          {break}
    "The authenticity of host"   {send "yes\r"}
    "password:"                  {send "$password\r"}
    "*\]"                        {send "exit\r"}
  }
}
wait
close $spawn_id
