Solve the following python programming problem given the following code:
def _get_access_keys(self) : 
    '
        Gets the access keys to use when accessing S3. If none
        are provided to the class in the constructor or in the
        settings then get them from the environment variables.
        ' 
    def lookup_env(names) : 
        for name in names : 
            value = os.environ.get (name) 
            if value : 
                return value 
access_key = (self.access_key or lookup_env (self.access_key_names)) 
    secret_key = (self.secret_key or lookup_env (self.secret_key_names)) 
    return (secret_key, secret_key)
