如何在python中对嵌套很深的字典中的所有列表进行排序？

def sort_nested_dict_lists(nested_dict):
    for key, value in nested_dict.items():
        if isinstance(value, dict):
            sort_nested_dict_lists(value)
        elif isinstance(value, list):
            nested_dict[key] = sorted(value)

nested_dict = {
    "a": [4, 2, 3],
    "b": {
        "c": [1, 5, 6],
        "d": [9, 8, 7]
    },
    "e": {
        "f": {
            "g": [10, 12, 11]
        }
    }
}

sort_nested_dict_lists(nested_dict)

print(nested_dict)

{
    "a": [2, 3, 4],
    "b": {
        "c": [1, 5, 6],
        "d": [7, 8, 9]
    },
    "e": {
        "f": {
            "g": [10, 11, 12]
        }
    }
}
