20,315 PointsPython import issues
I am at university and I have come into contact with a technology I would now consider myself quite familiar with, Flask. In the module however there is an issue it seems all students are encountering and I am of the mind that this is a mistake.
We are being told to import a file from a directory as such:
from app import app
With a directory named app and a file named app.
My understanding of imports in python was:
from file import Class
Am I wrong here? Or am I misunderstanding?

Python Development Techdegree Student 36,888 PointsHi Josh,
Python's imports can be confusing, not least because you can import various different entities using essentially the same syntax. You can import variables, functions, classes, modules and packages, and it's not always obvious just by looking at an import statement what level of entity is being imported.
In the specific case of Flask, the situation is that flask (lowercase) is a package, and Flask (titlecase) is a class. So you are importing the Flask class from the flask package. This is very similar to your experience, except that we are importing from a package (which in this case is a collection of a files) instead of from a single file.
Hope that clears things up,
Cheers
Alex
