1. 列表和元组简介
列表:用中括号[]包裹,元素的个数及元素的值可以改变。
元组:用小括号()包裹,不可用更改。
通过切片运算[]和[:]可以得到子集。
2.列表
示例:
List = [1, 2, 3, 4] print List print List[0] print List[1:3] List[3] = 5 print List
运行结果:
[1, 2, 3, 4] 1 [2, 3] [1, 2, 3, 5]
3. 元组
示例:
Tuple = ('Today', 'is', '11', '20') print Tuple print Tuple[0] print Tuple[0:2] Tuple[1] = 'are' print Tuple
运行结果:
Traceback (most recent call last): File "C:UsersAdministratorworkspacepracticesrcpractice_testdailytest.py", line 5, in <module> ('Today', 'is', '11', '20') Today ('Today', 'is') Tuple[1] = 'are' TypeError: 'tuple' object does not support item assignment
