Flask confusion with app

Question

I am starting a flask project, and in my code I have

from flask import Flask, render_template, abort app = Flask(__name__) 

Now what exactly is app?

I am following this guide and I am particularly confused about the structure because he has chosen to have directory named app/ and is his app/__init__.py he has

from flask import Flask app = Flask(__name__) from app import views 

and in his app/views.py he has

from app import app 

What the hell is it with all these app's?!

Answer 1

I think the main confusion is in the line:

from app import app 

You have a python package (a folder with __init__.py file) named "app". From this folder, you are now importing the variable "app" that you defined below in __init__.py file:

app = Flask(__name__) 

Rename the folder from app to say "myproject". Then you will call

from myproject import app 

Also, you will import views as

from myproject import views
