Solve the following python programming problem given the following code:
def enforce(self, * executables) : 
    '
        Puts the executables to enforce mode - the policies are enforced, but only break attempts will be logged -.

        :param executables: The executables to change.
        :type executables: positional arguments of :class:`str`

        Example:
        ::

            from provy.core import Role
            from provy.more.debian import AppArmorRole

            class MySampleRole(Role):
                def provision(self):
                    with self.using(AppArmorRole) as apparmor:
                        apparmor.enforce("/bin/ping", "/sbin/dhclient")
        ' 
    self.__execute_batch ('aa-enforce', self) 

    
    

    Fix the buggy line: self.__execute_batch ('aa-enforce', self)

#Here is Python program to fix the buggy line: self.

self.__execute_batch ('aa-enforce', executables)
