How to import python module as a specific reference?

Question

I had a file at db/connection.py. I moved the file and now the path is project/db/connection.py. Previously I imported that file using this syntax:

import db.connection

And somewhere in the code I had access to the file:

db.connection.open_connection()

Since now the file is moved, I know only two options to import the file: using import and from import keywords. But both of them will change the reference to the file. I'll show you what I mean. If I use import:

import project.db.connection

Then the new reference is project.db.connection and I need to change the code that accesses the file as well, so that it becomes:

project.db.connection.open_connection()

If I use from import:

from project.db import connection

The same problem, but now the reference is connection.

I thought I could do that:

from project import db.connection

But python gives me an error at that line of code:

from project import db.connection
                     ^

SyntaxError: invalid syntax

So if it's possible, how to import the new file having the reference db.connection, so I don't need to change the code that accesses that file?

If I understand your question correctly, you can just do: import x as db.connection — einekratzekkatze

@einekratzekkatze, unfortunately, the same syntax error at line import project.db.connection as db.connection — g00dds

@deceze, this syntax imports the file as connection, but not as db.connection — g00dds

Yeah, but if you always take care to import it as connection, then that's fine… — deceze

from project import db

Maybe you need to add __init__.py file in project and in project/db.
