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         


        

Answer 1

I think the following is more elegant:

def delete_keys_from_dict(dict_del, lst_keys):
    if not isinstance(dict_del, dict):
        return dict_del
    return {key:value for key,value in ((key, delete_keys_from_dict(value)) for key,value in dict_del.items()) if key not in lst_keys}
