That is correct. But why did you try using interact() method in the
first place?
I just want to know to see if I could improve the documentation.
After you send the password the 'scp' command should finish quickly
and exit,
so there would be nothing for a human to interact with.

You could also try using the run() function which is a simplified
interface to pexpect.
Something like this might work:
    pexpect.run ('scp u... at server.com:/home/config/role{/file1,/files/
file2,/files/file3} /tmp',
        events={'(?i)password': 'server_password'})
That's all there is to it. The run() function will run the given scp
command.
When it see 'password' in the output it will send the server_password.
