Elegant way to remove fields from nested dictionaries

Question

I had to remove some fields from a dictionary, the keys for those fields are on a list. So I wrote this function:

def delete_keys_from_dict(dict_del, lst_key

Using the awesome code from this post and add a small statement:

    def remove_fields(self, d, list_of_keys_to_remove):
        if not isinstance(d, (dict, list)):
            return d
        if isinstance(d, list):
            return [v for v in (self.remove_fields(v, list_of_keys_to_remove) for v in d) if v]
        return {k: v for k, v in ((k, self.remove_fields(v, list_of_keys_to_remove)) for k, v in d.items()) if k not in list_of_keys_to_remove}
