在嵌套字典中打印值时出现问题

def print_dict_values(d):
    for key, value in d.items():
        if isinstance(value, dict):
            print_dict_values(value)  # 递归调用自己处理字典
        else:
            print(value)  # 打印值

# 假设我们有一个嵌套字典如下:
my_dict = {
    "key1": "value1",
    "key2": {
        "key3": "value3",
        "key4": {
            "key5": "value5"
        }
    },
    "key6": "value6"
}

# 调用函数打印字典中的值
print_dict_values(my_dict)

value1
value3
value5
value6
