  • [python]python列表、元组

    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
