各位

又碰到一个怪问题，请看下面的3个Python文件

main.py:

from a import *

from b import *

 

a.py:

Host = "http://www.163.com"

Hosts = {"site":[Host,]}

 

b.py

Host =” http://www.google.com”

 

在Shell环境下执行下列代码

import main

main.Hosts

 

但是输出结果是

{'site': ['http://www.163.com']}

 

按我的理解应该是

{‘site’:[‘http://www.google.com’]}

 

请问是怎么回事啊？？？

有什么不对么，

你的 Hosts = {"site":[Host,]}  后，
修改 Host 会改变 Hosts ？

Python 里边 字符串可是 不可变对象，
不能作为"引用" 来用
