python - Why can't I import the page.py module in the PageObjects directory?

Question

I am following the flaskr tutorial so my code is similar to (https://flask.palletsprojects.com/en/1.1.x/tutorial/). I am also following the Selenium PageObjects tutorial (https://selenium-python.readthedocs.io/page-objects.html).

└── setup.py

At the beginning I am importing my PageObject main.py file; PythonOrgSearch class in flaskr/auth.py.

from flask import (
    Blueprint, flash, g, redirect, render_template, request, session, url_for
)

from .PageObjects.main import PythonOrgSearch

The PythonOrgSearch class imports page module.

import unittest
from selenium import webdriver
import sys

import page

class PythonOrgSearch(unittest.TestCase):

Why can't it import the page.py module?

Answer 1

You may need an __init__.py file in the PageObjects directory.
