【382】利用 namedtuple 实现函数添加属性

namedtuple 能够实现类似类的效果，tuple 的元素可以通过属性的形式返回，如下所示：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

from collections import namedtuple Student = namedtuple('stu', ['Name', 'Age', 'Height', 'Weight']) Alex = Student('Alex', 23, '173', '63') Vincent = Student('Vincent', 20, '172', '57')   Alex.Name Alex.Age Alex.Height Alex.Weight   Vincent.Name Vincent.Age Vincent.Height Vincent.Weight   output: 'Alex' 23 '173' '63'   'Vincent' 20 '172' '57'

因此若是想要让函数返回属性的效果，只需让函数的返回值是 namedtuple 即可，如下所示

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

from collections import namedtuple def get_info(Name, Age, Height, Weight):     Student = namedtuple('stu', ['Name', 'Age', 'Height', 'Weight'])     return Student(Name, Age, Height, Weight)   Alex = get_info('Alex', 23, '173', '63') Alex.Name Alex.Age Alex.Height Alex.Weight   output: 'Alex' 23 '173' '63'
