but remove package ask like

After this operation, 2,621 kB disk space will be freed.
Do you want to continue [Y/n]?
how to give Y in program via python

Answer 1

Configure apt-get not to ask (see the apt-get man page:

apt-get --assume-yes remove xxx

For tools that cannot be configured, use pexpect to steer the process. pexpect lets you listen for output from a subprocess, and send input based on a simple API:

import pexpect

ag = pexpect.spawn('apt-get remove xxx')
ag.expect('Do you want to continue')
ag.send('Y')
ag.wait()
ag.close()
