Tuple ¶

叫做 tuple，用小括号、或者无括号来表述，是一连串有顺序的数字。

a_tuple=(12,3,5,15,6)another_tuple=12,3,5,15,6

List ¶

而list是以中括号来命名的:

a_list=[12,3,67,7,82]

两者对比 ¶

他们的元素可以一个一个地被迭代、输出、运用、定位取值:

forcontentina_list:print(content)""" 12 3 67 7 82 """forcontent_tupleina_tuple:print(content_tuple)""" 12 3 5 15 6 """

下一个例子，依次输出a_tuple和a_list中的各个元素：

forindexinrange(len(a_list)):print("index = ",index,", number in list = ",a_list[index])""" index = 0 , number in list = 12 index = 1 , number in list = 3 index = 2 , number in list = 67 index = 3 , number in list = 7 index = 4 , number in list = 82 """forindexinrange(len(a_tuple)):print("index = ",index,", number in tuple = ",a_tuple[index])""" index = 0 , number in tuple = 12 index = 1 , number in tuple = 3 index = 2 , number in tuple = 5 index = 3 , number in tuple = 15 index = 4 , number in tuple = 6 """
