Or easier using 'return':

     def ssh_command_output_contains(self, cmd, exp):
        stdout, _ = self.ssh_command(cmd)
        for line in stdout:
            if exp in line:
                return
        self.fail('"%s" output does not contain "%s"' % (cmd, exp))

Regardless, thanks for the cleanup!
