How do I import my error_handler module into my app.py in flask?

I separated my flask errorhandlers into a separate module called 'error_handlers.py' within my 'app.py' directory. I have tried importing the error_handlers module into the app module but i keep getting an ImportError:

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

I looked up a similar question and added blueprint but i'm still getting the same error. Please is there anything I'm doing wrong. My code below:

app.py

import os

from error_handler import *

from flask import Flask, flash, jsonify, redirect, render_template, request, session, abort
from flask_session import Session
from tempfile import mkdtemp

from helpers import lookup, login_required

# Configure application
app = Flask(__name__)
app.register_blueprint(error_handlers.blueprint)
...

error_handlers.py

from app import app
from flask import render_template, Blueprint

blueprint = Blueprint('error_handlers', __name__)


@blueprint.app_errorhandler(404)
def page_not_found(e):
return render_template("errors/404.html")
