pexpect telnet login from one device to another

[kaf3773]

I am trying to use pexpect to telnet to a device and then subsequently telnet from that device to another device and then output the result of a command on the second device but i am unable to. Here is the script i wrote and the error i am getting

I will appreciate help very much. Thanks

import pexpect
 
child = pexpect.spawn('telnet 192.168.2.45');
 
child.expect('assword:');
child.sendline('getin');
 
child.expect('AS-C5350-02>');
child.sendline('telnet 192.168.1.2'); 
child.expect('\nTrying 192.168.1.2 ... Open\n\n\nUser Access Verification\n\nPassword:');
child.sendline('cisco'); 
child.expect('ipipgw01>'); 
child.sendline('sh clock');
child.sendline('exit');
 
child.expect(pexpect.EOF);
 
print child.before;
 

Here is the error i keep getting
