从父目录导入 python

Question

I have the following structure:

   app/
     code/
       script.py -- has a function called func
     main.py

How can I import script.py from main.py ?

I tried from code.script import func and I got ModuleNotFoundError: No module named 'code.script'; 'code' is not a package ModuleNotFoundError: No module named 'code.script'; 'code' is not a package

Answer 1

Place a __init__.py file in the code directory. This will allow your main.py code to import it as a module like you have tried there.

Answer 2

Indeed the best way is to add __init__.py in code directory because when a regular package is imported __init__.py file is implicitly executed and the objects it defines are bound to names in the package's namespace.

FYI, as an alternative you can also to this in your main.py before the import:

import sys
sys.path.append("/path/to/script.py")
