ImportError in Python 3.8.6

I am using python 3.8.6 to build a simple web app with the module Flask and the folder structure looks exactly like this:

web-app   ├── main.py   └── site       ├── __init__.py       ├── auth.py       └── models.py  

In __init__.py there is a function called create_app() and this function must be accessed by my main.py.

# site/__init__.py  from flask import Flask    def create_app():      app = Flask(__name__)      app.config.SECRET_KEY = ""      return app  enter code here  

In my main.py I am importing the create_app() like this:

# main.py  from .site import create_app    app = create_app()    if __name__ == "__main__":      app.run(debug=True)  

But when I try to run my main.py, raises the following error:

Traceback (most recent call last):    File "c:/Users/User/Desktop/website/main.py", line 1, in <module>      from .site import create_app  ImportError: attempted relative import with no known parent package  

I've already try to import without the dot before the folder's name, like from site import create_app, but that also didn't work, the error message just changes to ImportError: cannot import name 'create_app' from 'site' (C:\Python38\lib\site.py).
