如何操作python语言中的列表并获取对应的元素

1、定义列表

>>> a = [1,2,3,4,5,6,7,8,9,0];
>>> a;
[1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
>>> 

2、切片

>>> b = ["a","c","f","m","n","k","e"];
>>> b[2];
'f'
>>> b[3:7];
['m', 'n', 'k', 'e']
>>> b[-3:-1];
['n', 'k']
>>> b[-4]
'm'
>>> b[2:7:2];
['f', 'n', 'e']
>>> 

3、列表相加

>>> c = [12,23,34,45,56,67];
>>> d = ["A","F","E","R","T","Y"];
>>> c + d;
[12, 23, 34, 45, 56, 67, 'A', 'F', 'E', 'R', 'T', 'Y']
>>> 

4、列表重复显示

>>> e = [1,3,5,7,9];
>>> e*4;
[1, 3, 5, 7, 9, 1, 3, 5, 7, 9, 1, 3, 5, 7, 9, 1, 3, 5, 7, 9]
>>>
