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

def delete_keys_from_dict(dict_del, lst_keys):
    for k in lst_keys:
        try:
            del dict_del[k]
        except KeyError:
            pass
    for v in dict_del.values():
        if isinstance(v, dict):
            delete_keys_from_dict(v, lst_keys)

    return dict_del
