如何在字典中返回最大值对应的key？

def get_key_with_max_value(dictionary):
    values = list(dictionary.values())
    max_value = max(values)
    for key, value in dictionary.items():
        if value == max_value:
            return key

# 示例字典
my_dict = {'a': 10, 'b': 5, 'c': 15, 'd': 10}

# 调用函数获取最大值对应的key
max_key = get_key_with_max_value(my_dict)
print("最大值对应的key是:", max_key)

最大值对应的key是: c
