导语 自2020年Python 2停止维护至今，5年过去了。虽然还有很多项目依旧在使用Python 2，但不可否认，无论是企业还是社区，都在努力向Python 3迈进。Python ...

defaultdict的核心原理是它在初始化时接受一个工厂函数（factory function），这个函数用于生成默认值。当访问一个不存在的键时，defaultdict会调用这个工厂函数来生成默认值，并将其插入到字典中。这使得defaultdict在处理图算法、计数器等需要频繁检查键是否存在的场景时，比普通字典更加高效和简洁。

*args 和 **kwargs的主要价值在于它们允许开发者编写更加通用和灵活的代码。无论是处理不确定数量的输入，还是需要在函数中传递额外的参数，*args 和**kwargs都能提供极大的便利。
