this code in user.py file

When I run this code I get the following error: File “c:Pythonapp.py”, line 3, in
from user import db, Hasta # user.py’den ilgili sınıfları ve veritabanını içe aktarın
^^^^^^^^^^^^^^^^^^^^^^^^^^
File “c:Pythonuser.py”, line 6, in

^^^^^^^^^^^^^^^^^^^^^^^^^^
ImportError: cannot import name ‘db’ from partially initialized module ‘user’ (most likely due to a circular import) (c:Pythonuser.py)
PS C:Python>

Even though my user.py and app.py files are in the same directory, I get an error. I tried every way but couldn’t find it. Can you help me. Additionally, although I researched this error, I could not do it.
