非常简单的导入在 python 中不起作用

Question

main.py:

import second
from second import *

print(second.a)

second.py:

a = "testA"
b = "testB"

Error:

AttributeError: module 'second' has no attribute 'a'

Importing wasn't working on a more complex program. Tried to test it simply and it's not working.

Inside the project folder, there are the other .py files as well as a __pycache__ folder

Doing ↓ doesn't work either:

from second import a, b

Answer 1

Your code works for me as well. I think it maybe caused by your .pyc file which you run your code before.

Delete .pyc file in your package and rerun your code.

Or you can try running your code in a new environment.

Answer 2

I figured it out!

The answer was quite simple, and it was to create a virtual environment.
