导入错误 Python 3 与 tkinter 类

Question

I know this is probably quite easy to solve but I dont know the answer.

I have the following folder structure in my python3 project:

---UserInterface
------__init__.py
------MainApplication.py
------StartPage.py

(PS my __init__.py is empty)

Now I want to add the StartPage to my MainApplication and I try the following import.

from . import StartPage

I am getting the following error: ImportError: cannot import name 'StartPage' from '__main__'.

Can anyone tell me where the problem with importing is? (My main method is inside my MainApplication.py)

Answer 1

did you just try import StartPage ? the error text says that there is no StartPage in main . You run MainApplication and it gets the name main after launch. This means that an attempt is being made to import StartPage from the MainApplication . But it's not there
