从Python字典中移除以字符分隔的命名键列表

def remove_keys_from_dict(dictionary, keys):
    key_list = keys.split('.')  # 将字符分隔的命名键列表拆分为单独的键
    for key in key_list:
        if key in dictionary:  # 检查字典中是否存在该键
            del dictionary[key]  # 从字典中删除该键值对

# 示例用法
my_dict = {
    "person": {
        "name": "John",
        "age": 30,
        "address": {
            "street": "123 Street",
            "city": "New York"
        }
    },
    "company": "ABC"
}

keys_to_remove = "person.address.city"  # 字符分隔的命名键列表

remove_keys_from_dict(my_dict, keys_to_remove)

print(my_dict)

{
    "person": {
        "name": "John",
        "age": 30,
        "address": {
            "street": "123 Street"
        }
    },
    "company": "ABC"
}
