I want to import a class from a .py to another .py but it says : no module named "example"

Question

My folders looks like this:

Code_Sources (folder)
    main.py
    Class (folder)
        game_class.py
        player_class.py

I made in game_class.py:

from player_class import *

And when I run the game_class.py I have no problem. But when I run main.py which contains:

import pygame

from Class.game_class import Game

if __name__ == "__main__" :
    pygame.init()
    game = Game()
    game.run()

It says that an error comes from game_class.py and No module named 'player_class'. I don't understand why.

I tried the method of init.py but it doesn't work.

What exactly did you try with `init.py`? – Abhijit Sarkar Dec 18 '22 at 11:04 — Abhijit Sarkar, Dec 18 '22 at 11:04

Check out python documentation on packages.

Also it's good practise to follow style guide for python code PEP8, especially the package and module names section.

Let's rebuild your code structure a bit.

code_sources
  | __init__.py
  | main.py
  | classes
      | __init__.py
      | game_class.py
      | player_class.py

The names of directories are still vague imo, think about giving them name that reflect what they are grouping inside.

All your internal imports should look like this now:

from code_sources.classes import player_class

Even when you are importing something between game_class and player_class

Also try to avoid asking questions that already has been answered or are well documented by the software creators. Python is perfect example of great documentation.
