HHello,

import pexpect
cmd2="sudo mount -t cifs //<ip address>/FinalWork  /mnt/win"
child = pexpect.spawn(cmd2)
i = child.expect([' password .* ', pexpect.EOF, pexpect.TIMEOUT])
if i == 0:
   print "******************sending pwd"
   child.sendline(pwd) #Here pwd is password for sudo
   print "+++++++++++given password : " + pwd
elif i == 1:
   print "--------------EOF"
elif i == 2:
   print "%%%%%%%%%%%%%%TIMEOUT"

print "^^^^^^^^^^^^^^after pwd affair"
child.close()
