so a.insert(0, x) inserts at the front of the list, and a.insert(len(a), x) is equivalent to a.append(x).本方法是在指定的位置插入一个对象，第一个参数是要插入元素的位置，a.insert(0, x)是在当前列表的前面插入，a.insert(len(a),x)等效于a.append(x)。list...

In this example, you first add an integer number, then a string, and finally a floating-point number. However, you can also add another list, a dictionary, a tuple, a user-defined object, and so on.Using .append() is equivalent to the following operation:...

你只能使用队列的基本操作 —— 也就是push to back、peek/pop from front、size和is empty这些操作。 你所使用的语言也许不支持队列。 你可以使用 list (列表)或者 deque(双端队列)来模拟一个队列 , 只要是标准的队列操作即可。 示例: 输入: ["MyStack", "push", "push", "top", "pop", "empty"]...
push to back,从队列的尾部加入新的元素; peek/pop from the front, 从队伍的前面查看或者抽取; size; isempty,判断是否为空; 可以使用 list 或者 dqueue 双端队列,只要使用队列的标准操作即可 下面的题目附带的例子: 2 解题思路 用队列实现栈 = 用先进先出,模拟后进先出 ...
