Pexpect, yes. Making sudo not ask for a password? Only if you tell sudo to only not ask for a password for _this_ file. Telling sudo to not require a password at all is asking for trouble. Also, modifying sudo to allow this script to run without a password would require that to be done on every machine that the OP wants to run on. OP: use pexpect.
