Python 的 DeepCopy 的迭代版本
Python 2.5.2 是否有深度复制迭代版本的现有实现？ 复制模块中提供的深度复制方法是递归的，并且在大型树上失败。 我无法在运行时安全地增加堆栈限制。

我确实追踪到了这一点：

我还没有测试过，但看起来它有潜力。
Is there an existing implementation of an iterative version of deepcopy for Python 2.5.2? The deepcopy method available from the copy module is recursive and fails on large trees. I am not in a position where we can safely increase the stack limit at runtime.

I did track this down:

I haven't tested it, but it looks like it has potential.

我不确定这是否有意义。
deepcopy的全部意义不就是每个对象都会要求其子对象复制自己吗？想必您确切地知道要复制的对象类型以及它的子对象是什么样子，所以如果我是您，我只会编写自己的函数来复制它。 不应该太难。
I'm not sure this would make sense. Isn't the whole point of
deepcopythat each object will ask its children to copy themselves?Presumably you know exactly what kind of object you're copying and what its children look like as well, so if I were you, I'd just write my own function to copy it. Shouldn't be too hard.
也许它可以与 Stackless Python 一起工作
Maybe it would work as such with Stackless Python
