如何导入模块？

Question

The directory structure is as follows:

folder1
  __init__.py
  file1.py
  folder2
    file2.py

If I write file2.py as follows:

from folder1 import file1

I get the error No module named 'folder1' .

If I write file2.py as follows:

from ..folder1 import file1

I get the error ValueError: attempted relative import beyond top-level package .

How can I import file1 from file2?

Answer 1

Try the following:

import sys
sys.path.append("..")
from .. import file1
