从文件夹导入Python

Question

I have such structure of application

mainApp.py
   |_Folder1
       |_fileFromFolder1.py
   |_Folder2
       |_fileFromFolder2.py

I want in fileFromFolder1.py import object from fileFromFolder2.py

I know that one of solution is to sys.path.insert(0, '/path/to/application/app/folder') but is it possible to make without absolute path

Answer 1

You need(not strictly need in Python3, but still really really should have) __init__.py files in directories you would like to import code from. An __init__.py file makes the difference between a plain directory and a Python package

mainApp.py
   |_Folder1
       |__init__.py
       |_fileFromFolder1.py
   |_Folder2
       |__init__.py
       |_fileFromFolder2.py
