[Tutor] need to automate connection

[Payal Rathod]

Hi,
I need to automate connection to a IP like this. The IP (or domain name) 
is taken from command line or from user (whichever is easier for me to 
code). It should emulate,

telnet 127.0.0.1 25

mail from: <test at test.com>
250 ok
rcpt to: <support at example.com>
250 ok
quit

Can Python do this for me? How do I start?

With warm regards,
-Payal
