list.insert(i, x) 在给定的位置插入一个元素。第一个参数是要插入的元素的索引,所以 a.insert(0, x) 插入列表头部, a.insert(len(a), x) 等同于 a.append(x) 。 list.remove(x) 移除列表中第一个值为 x 的元素。如果没有这样的元素,则抛出 ValueError 异常。

list有一些非常有用的方法,比如append,extend,insert,remove,pop,index,count,sort,reverse,copy等。 举个例子: >>> fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana'] >>> fruits.count('apple') 2 >>> fruits.count('tangerine') ...
list.insert(i, x) 1. 在给定位置插入一个元素。第一个参数是准备插入到其前面的那个元素的索引,所以 a.insert(0, x) 在列表的最前面插入,a.insert(len(a), x) 相当于 a.append(x)。 list.remove(x) 1. 删除列表中第一个值为 x 的元素。如果没有这样的元素将会报错。
Tuples are unchangeable, meaning that we cannot change, add or remove items after the tuple has been created. Allow Duplicates Since tuples are indexed, they can have items with the same value: Example Tuples allow duplicate values:
