You wouldn't ask for the password with optparse. optparse just parses
command-line options.

If you must provide a command-line argument to accept a password, then check if
the option value is None (i.e. the user did not provide it), then prompt the
user using getpass.getpass(). That function will not print the user's input to
the screen.
