Force importing module from current directory

Question

I have package p that has modules a and b. a relies on b:

b.py contents:

Answer 1

Because there is an __init__.py file in /p. This file tells Python: "All modules in this folder are in the package p".

As long as the __init__.py file exists, you can import b as p.b, no matter where you are.

So the correct import in b.py would be: import p.a
