使用列表作为堆栈在python中实现堆栈

Question

我正在创建一个具有以下功能的堆栈演示：

( Method ) __init__(self, n) => How can I initial the fix  n len of stack. ?
( Method ) IsEmpty      => Done by using lists as stacks 
( Method ) IsFull       => Done by using lists as stacks 
( Method ) Push         => Done by using lists as stacks 
( Method ) Pop          => Done by using lists as stacks 

我正在做的代码

 class Stack(object) :

   def __init__(self) :
    self.items = []
   def push(self, item) :
    self.items.append(item)

   def pop(self) :
    return self.items.pop()

   def isEmpty(self) :
    return (self.items == []) 

if __name__ == "__main__":
    demoStack = Stack()
    demoStack.push(1)
    print demoStack.items

有人知道怎么做吗？

谢谢

Python的列表可能已经有了您想要的一切。如果您想要一些额外的功能，比如限制对象的最大数量，您应该将其子类化，或者用另一个类将其包装起来。
