How to realize ssh & scp by Python

[刚 王]

I would like to write a Python code like this:

It can login a host by SSH
after login the host, use SCP to get a remote file, so it can deliver file to the host.
then execute the program
then leave the host

For example :

STEP 1. ssh xxxx_yyy at 123.45.67.89
STEP 2. Enter the password automatically 
STEP 3. run " scp -r zzz at 123.45.67.90:/home/xxx/program ."
STEP 4. Enter the password for SCP automatically 
STEP 5. run "./program"
STEP 6. run " exit"

I know telnetlib can help us with telnet, and how to deal with this SSH situation in Python?

Thanks a lot for your help :)
