Import local python file as class

Question

I have a Flask app created, and my folder structure looks like this:

-- Folder
  ---- app.py
  ---- page.py
  ---- __init__.py

I'm trying to reference page.py as a class, using:

from flask import render_template
from flask import Flask, redirect, url_for
import logging
import json
import requests
import os
import page as Page 

""" Initialise the app """
app = Flask(__name__)

@app.route("/")
def home():
    return render_template('index.html')

if __name__ == "__main__":
    app.run(debug=True)

But I get the error:

Cannot import 'page' due to syntax error 'invalid syntax (<unknown>, line 3)'pylint(syntax-error)

Where am I going wrong?

My class file looks like this:

class Page:
    def __init__(self, title, environ)
    self.title = title 
    self.environment = environ

I tried from .page import Page

but still got the error:

Cannot import 'page' due to syntax error 'invalid syntax (<unknown>, line 3)'pylint(syntax-error)

Answer 1

It is due to syntax error in line 3.

class Page:
    def __init__(self, title, environ) # no colon
    self.title = title # no indentation
    self.environment = environ

If this is how it looks like (as you have attached), there is no colon (:) and indention after def where it should belong. Therefore, your page.py should look something like:

class Page:
    def __init__(self, title, environ):
        self.title = title 
        self.environment = environ

Answer 2

Have you tried:

from .page import Page

Answer 3

page.py cannot be referenced as a class as it is just a python file. I presume there is a class within this file called Page.

Therefore, you will need to import the Page class from the page.py file with the following syntax:

from .page import Page

Answer 4

The reason you are having that error is because you aren't accessing the package first, you are trying to go straight to the module, but it doesn't work that way.
You have to access the package first, then the module, then the class and so on.

What you should have then is

from Folder.page import Page

or to work with relative path use

 from .page import Page

Hope this helps One last piece of advice would be to use correcting naming patterns which means classes start with uppercase letters, that will make imports easier for you in the long run

class Page:
    def __init__(self, title, environ)
        self.title = title 
        self.environment = environ

Note the indentation change
