从另一个文件夹导入 Python Package

Question

I have seen many questions and answers for this same, but none of them solved mine. Please have a look into this,

This is my folder structure,

code/ 
  helloworld.py
stdlib/
  stdio.py
  stddraw.py 
  __init__.py

Inside __init.py i have done

from . import stdio

Inside helloworld.py, i have done

from ..stdlib import stdio
stdio.writeln("Test")

But it says me an error saying, " attempted relative import with no known parent package " Can anyone please explain me what i am doing wrong in this case?

Answer 1

As the error says, you would need a "parent package" for what you're currently doing to work. Something like this:

parent/
 __init__.py
 code/ 
  helloworld.py
 stdlib/
  stdio.py
  stddraw.py 
  __init__.py
