Getting `Top `level package` error when importing module in `python3`

Question

I am having directory structure as

-Practice
 -Connect
    -connect.py -> having function abc
    -__init__.py
 -Pytest
    -__init__.py
    -file.py

file.1 contents

from ..connect.connect import abc
abc()

Getting error as

ValueError: attempted relative import beyond top-level package

I can use import from parent directory as

from connect.connect import abc
abc()

This is working. Need to know why relative import is not working

As people suggested i have added init .py in Practice directory and still getting same error

Answer 1

您需要一个__init__.py位于顶级Practice文件夹中，因此 Python 知道它本身应该是一个包，而不是一个恰好包含两个包的随机文件夹。

Answer 2

You need an __init__.py in your Practice directory too. Otherwise, Pytest and Connect are separate toplevel packages and not sibling subpackages of the Practice package. Hence the error you're getting.
