如何从上面一个文件夹中的python文件导入函数？

Question

This is a follow up to " How to import a Python class that is in a directory above? ", which gives how to import a file from the parent directory:

from .. import module

I to get a specific function from a file in the directory above.

This is my attempt: There is a file in the higher directory called topLevel.py which has a function called test_function .

from .. import topLevel
from topLevel import test_function

This is the error message:

ValueError: attempted relative import beyond top-level package

Answer 1

import sys 
sys.path.insert(0, "./../" )
from topLevel import test_function

test_function()
