import time
cmd = "runas /user:administrator notepad.exe"
proc = Popen(cmd, stdout=PIPE, stdin=PIPE, stderr=PIPE)

Are you open to using Pexpect instead? If yes, you can use the following:

import pexpect
cmd = "runas /user:administrator notepad.exe"
child_process = pexpect.spawn(cmd)
child_process.expect('assword')
child_process.sendline(password)
