Linking files

[cosmere]

Hello I'm trying to create a basic game in python using OOP style programming. The problem is that I'm not sure how to link my files. I currently have main.py, a game.py and a logic.py. I would like to be able to run everything from my main.py through the start_game method. However if I run the code below I get the following error: TypeError: Main.start_game() takes 0 positional arguments but 1 was given. I'm just a beginner so I'm not sure if I'm approaching this the right way. My current code looks like this:

from game import Game

class Main():
def __init__(self):
self.game = Game
def start_game():
player_choice = Game.player_choice()
print(player_choice)

if __name__ == '__main__':
main = Main()
print(main.start_game())
