此时两个对象的引用计数都是 1,而实际上程序已经不再有变量引用它们,系统应该回收它们,此时 Python 的垃圾回收器就可能没那么快,要等专门的循环垃圾回收器(Cyclic Garbage Collector)来检测并回收这种引用循环。

Garbage Collection: The runtime environment includes a garbage collector that automatically manages memory, freeing up resources that are no longer needed. This feature eliminates the need for manual memory management, reducing the risk of memory leaks and improving application performance. Language Intero...
4.另外元数据也是序列化的实现基础,能够将对象中的所有成员序列化到内存,从而完成类型远程传输,保存。 5.Metadata 是GC (Garbage Collector)追踪各种不同对象的生命周期,管理各种对象内存生命周期的关键连接数据。 这里需要重点说明一下,C#禁止类似于C++的多继承,并且所有对象都是继承于System.object,这个为所有的类型...
