1,列表中添加一个元素
>>> name= ["jim","tom","luch","jon","jia"]
>>> name.append("key")
>>> name
[‘jim‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
2,列表中查找元素的索引
>>> name
[‘jim‘, ‘ka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
>>> name.index(‘jim‘)
0
>>> name.index(‘ka‘)
1
3,通过索引在ka的前面添加kaka
>>> name
[‘jim‘, ‘ka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
>>> name.insert(name.index(‘ka‘),‘kaka‘)
>>> name
[‘jim‘, ‘kaka‘, ‘ka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
4,直接删除列表中的元素
>>> name
[‘jim‘, ‘kaka‘, ‘ka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
>>> name.remove(‘jim‘)
>>> name
[‘kaka‘, ‘ka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
5,通过索引删除
>>> name
[‘kaka‘, ‘ka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
>>> del name[1]
>>> name
[‘kaka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
6,通过索引更改列表中的元素
>>> name
[‘kaka‘, ‘wen‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
>>> name[1]="kaka"
>>> name
[‘kaka‘, ‘kaka‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
7,统计列表中相同元素的个数
>>> name
[‘kaka‘, ‘kaka‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘]
>>> name.count(‘kaka‘)
2
8,列表元素正向排序
>>> name
[‘kaka‘, ‘kaka‘, ‘tom‘, ‘luch‘, ‘jon‘, ‘jia‘, ‘key‘, 1, 2, 30]
>>> name.sort()
>>> name
[1, 2, 30, ‘jia‘, ‘jon‘, ‘kaka‘, ‘kaka‘, ‘key‘, ‘luch‘, ‘tom‘]
9.列表元素反向排序
>>> name
[1, 2, 30, ‘jia‘, ‘jon‘, ‘kaka‘, ‘kaka‘, ‘key‘, ‘luch‘, ‘tom‘]
>>> name.reverse()
>>> name
[‘tom‘, ‘luch‘, ‘key‘, ‘kaka‘, ‘kaka‘, ‘jon‘, ‘jia‘, 30, 2, 1]
