元组 列表
作者: Hao 编辑: 莫烦 2016-11-03
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:
for content in a_list:
print(content)
"""
12
3
67
7
82
"""
for content_tuple in a_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：
for index in range(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
"""
for index in range(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
"""
