ImportError: cannot import name 'app' from partially initialized module 'market' (most likely due to a circular import)-Flask

Question

#market package
from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy
from market import routes
app = Flask(__name__)
app.config\['SQLALCHEMY_DATABASE_URI'\] = 'sqlite:///market.db'
db = SQLAlchemy(app)
----------
from market import db #(models)
----------
from market import app #(routes)
from flask import render_template
from market.models import Item
----------#run
from market import app
if __name__ == '__main__':
app.run(debug=True)

Structuring the code into packages then importing modules but then getting the above error
