A question about "Intra-package References"

[ChrisWang]

Hi all,

I have a simple question about "Intra-package References"
There are two source files and __init__.py in package MyPkg shown below:

|-MyPkg
-__init__.py
-example.py
-test.py

example.py is like this:

a = 5

and test.py is like this:

from . import example
 
print example.a

While I executed test.py, python said "ValueError: Attempted relative import in non-package". Could anybody tell me what's wrong with the code. Thanks!

My limited understanding is that you cannot use relative imports in a top-level module. There does not appear to be anything wrong.

Thank you. I've got the answer why the error happened.

"Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application should always use absolute imports."

So I made another main module with absolute imports, and also imports this test module. Everything is fine.

Thanks again for your help:)
Have a nice day!

You are welcome, and thank you for the feedback ChrisWang.
