如何获取python字典中与不同列表中的值相对应的所有内层嵌套键的列表？

def find_keys(dictionary, target_values, current_keys=[]):
    result = []
    for key, value in dictionary.items():
        if isinstance(value, dict):
            new_keys = current_keys + [key]
            result.extend(find_keys(value, target_values, new_keys))
        elif value in target_values:
            result.append(current_keys + [key])
    return result

dictionary = {
    'a': {
        'b': {
            'c': 1,
            'd': 2
        },
        'e': {
            'f': 3,
            'g': 4
        }
    },
    'h': {
        'i': {
            'j': 5,
            'k': 6
        },
        'l': {
            'm': 7,
            'n': 8
        }
    }
}

target_values = [1, 4, 7]

result = find_keys(dictionary, target_values)
print(result)

[['a', 'b', 'c'], ['a', 'e', 'g'], ['h', 'l', 'm']]
