列表（list）
增
append 向列表末尾追加
>>> a = [1, 2, 3] >>> a.append(‘1‘) >>> a [1, 2, 3, ‘1‘]
insert 插入到指定下标
>>> a = [1, 2, 3] >>> a.insert(1, ‘1‘) >>> a [1, ‘1‘, 2, 3]
删
remove
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> a.remove(‘e‘) >>> a [‘s‘, ‘h‘, ‘e‘, ‘p‘]
del
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘]
>>> del a[1]
>>> a
[‘s‘, ‘e‘, ‘e‘, ‘p‘]
pop 如果不传索引，默认删除最后的索引
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> a.pop() ‘p‘ >>> a [‘s‘, ‘h‘, ‘e‘, ‘e‘] >>> a.pop(0) ‘s‘ >>> a [‘h‘, ‘e‘, ‘e‘]
查
切片 左边的索引:右边的索引(:步长)
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> a[:] [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘]
>>> a[-4:-1:2] [‘h‘, ‘e‘]
index 查指定元素的索引
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> a.index(‘h‘) 1
count 查指定元素的个数
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> a.count(‘e‘) 2
其它操作
clear 清空列表（python3）
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> a.clear() >>> a []
reverse 反转
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> a.reverse() >>> a [‘p‘, ‘e‘, ‘e‘, ‘h‘, ‘s‘]
sort 排序（按照ascii排序规则）
>>> a = [‘2s‘, ‘5h‘, ‘ce‘, ‘Be‘, ‘*p‘] >>> a.sort() >>> a [‘*p‘, ‘2s‘, ‘5h‘, ‘Be‘, ‘ce‘]
extend 扩展
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘] >>> b = [1, 2, 3, 4, 5] >>> a.extend(b) >>> a [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘, 1, 2, 3, 4, 5] >>> b [1, 2, 3, 4, 5]
copy (python3，浅copy，只copy一层)
>>> a = [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘, [‘today‘, ‘3-11‘]] >>> b = a.copy() >>> b [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘, [‘today‘, ‘3-11‘]] >>> b[4] = ‘e‘ >>> b [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘e‘, [‘today‘, ‘3-11‘]] >>> a [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘, [‘today‘, ‘3-11‘]] >>> b[5][0] = ‘tomorrow‘ >>> b [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘e‘, [‘tomorrow‘, ‘3-11‘]] >>> a [‘s‘, ‘h‘, ‘e‘, ‘e‘, ‘p‘, [‘tomorrow‘, ‘3-11‘]]
元组（tuple，只读列表）
只有两个方法：index()和count()
