(1)append()
>>> classmates = ['张三','李四','王五','赵六']
>>> classmates.append('xiaozuanfeng')
>>> classmates
['张三', '李四', '王五', '赵六', 'xiaozuanfeng']
(2)clear()#删除列表内所有元素
>>> classmates

>>> classmates.clear()
>>> classmates
(3)copy()
>>> classmates = ['张三', '李四', '王五', '赵六']
>>> classmates1 = classmates.copy()
>>> classmates1

>>>
(4)count()#计算参数在列表中的位置
>>> classmates = ['张三', '李四', '王五', '赵六']
>>> classmates.count('张三')

>>>
(5)extend()#用于在列表末尾一次性追加另一个序列中的多个值(用新列表扩展原来的列表)。
>>> classmates1 = ['张三','李四','王五']
>>> classmates2 = ['赵六','周七']
>>> classmates1.extend(classmates2)
>>> classmates1
