Python-lis中的命名元素

Question

在PHP中，我可以在如下列表中命名元素：

<?php
    list($name,$address,$home) = array("Alex","Taiwan","Vietnam");
    echo $address."\n";
?>

输出：台湾

在Python中它能起到同样的作用吗？我厌倦了这样做：

^{pr2}$

您可以创建自定义namedtuple数据类型：

from collections import namedtuple

# create a new data type (internally it defines a class ContactData):
ContactData = namedtuple("ContactData", ["name", "city", "state"])

# create an object as instance of our new data type
alex = ContactData("Alex", "Taiwan", "Vietnam")

# access our new object
print(alex)             # output: ContactData(name='Alex', city='Taiwan', state='Vietnam')
print(alex.city)        # output: Taiwan
print(alex[1])          # output: Taiwan
alex[0] = "Alexander"   # set new value
print(alex.name)        # output: Alexander
