Python 数据思维：元组基础

Python 数据思维：元组基础

元组 (Tuple)：不可变有序序列

创建元组

tup = 4, 5, 6

嵌套元组

tup_net = (4, 5, 6), (7, 8)

元组拆包

tup = (4, 5, 6)
a, b, c = tup
# a, b, c 的值分别为 4, 5, 6

嵌套拆包

tup = 4, 5, (6, 7)
a, b, (c, d) = tup
# a, b, c, d 的值分别为 4, 5, 6, 7

遍历拆包

seq = [(1, 2, 3), (4, 5, 6), (7, 8, 9)]
for a, b, c in seq:
    print('a={}, b={}, c={}'.format(a, b, c))

输出结果：

a=1, b=2, c=3
a=4, b=5, c=6
=, =, c=
