I already checked these documents, but it didn't help much on my specific requirement. I am new to Python. I was able to do it with shell scripting, but couldn't find a way around in python.

shell script:

Output:
for i in `cat filename` #here around cat filename i inserted a special symbol that is on the tilde key sitting next to number 1 on the keyboard, it just doesn't get visible here.
do
ssh -l user@$i
done

## Filename contains the list of IP Addresses separated by newline
