python 是否在用于列表元素的“del”之后创建一个新列表？

Question

I plan to use an array as a stack for a binary tree print operation. Will it be more efficient to use Del operator to delete a node object from the list when it is printed, or sould I substitute some check symbol instead of the node object?

Is del operation efficient? After del operation does python still store the list contagiously?

It is an efficieny question.

Answer 1

Generally Python List is perfect candidate for using it as a stack.
