Below is my code:

from pathlib import Path
import os
import sys
sys.path.insert(0, os.path.join(Path(__file__).parent.parent.parent.parent,'public'))
import utilities 
sys.path.insert(0, Path(__file__).parent.parent)
print(Path(__file__).parent.parent)
import publicmethods

I'm tring to import .py file in special directory. I can import utilities.py in os.path.join(Path(__file__).parent.parent.parent.parent,'public') but can't import publicmethods.py. I'm sure the publicmethods.py under the Path(__file__).parent.parent directory. What's wrong with it? Thanks!

ps: my dir structure like below:

c:\---|--projects|---spider|---public|      |---utilities.py|---website|--website|-- publicmethods.py|-- spiders|-- myspider.py

The code about import write in myspider.py

You must convert it to str before inserting it in sys.path:

sys.path.insert(0, str(Path(__file__).parent.parent))
