Python模块互相导入

Question

I have 2 modules importing each other, I try to nick a global variable from one of them into the other:

package1.module_1:

import package1.module_2 as module_2

SOME_VARIABLE = 5

package1.module_2:

import package1.module_1 as module_1

SOME_VARIABLE = module_1.SOME_VARIABLE 

It gives the error below:

AttributeError: 'module' object has no attribute 'module_2'

How can I fix it?

Answer 1

Answer: don't use as .

instead of:

import package1.module_2 as module_2

use:

import package1.module_2 

Answer 2

the right syntax is

from package1 import module_1

and

from package1 import module_2

but will led to circular import
