Python，无法从另一个文件夹导入文件

Question

Structure:

folder "a":
     __init__.py
     car.py
folder "b":
     tad.py

And I do in tad.py:

from a.car import *


ModuleNotFoundError: No module named 'a'

What can I do?? EDIT: I added init to the top level folder, and now throws this error:

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'

Answer 1

You should try

from .a.car import *

The leading dot goes one directory up in folder hierarchy.
