Ошибка при импортировании класса Python

Делаю игру на Pygame. Есть код игрока:

import pygame
from settings import *


class Player:

    def __init__(self):
        self.x = HALF_WIDTH
        self.y = HALF_HEIGHT
        self.player_right = pygame.image.load('knightRight.png')
        self.player_left = pygame.image.load('knightLeft.png')
        self.current_picture = self.player_left

    @property
    def pos(self):
        return self.x, self.y

    def movement(self):
        keys = pygame.key.get_pressed()
        if keys[pygame.K_w]:
            self.y -= player_speed
        if keys[pygame.K_s]:
            self.y += player_speed
        if keys[pygame.K_a]:
            self.current_picture = self.player_left
            self.x -= player_speed
        if keys[pygame.K_d]:
            self.current_picture = self.player_right
            self.x += player_speed

Есть код оружия:

import pygame
from settings import *
from main import player


class BadPistol:

    def __init__(self):
        self.x = HALF_WIDTH
        self.y = HALF_HEIGHT
        self.bad_pistol_pic = pygame.image.load('bad_pistol.png')
        self.colorkey = self.bad_pistol_pic.get_at((0, 0))
        self.bad_pistol_pic.set_colorkey(self.colorkey)

    @property
    def pos(self):
        return self.x, self.y

    def move(self):
        self.x = player.x
        self.y = player.y

main.py:

import pygame
from settings import *
from player import Player
from bad_pistol import BadPistol

pygame.init()

screen = pygame.display.set_mode((WIDTH, HEIGHT))
player = Player()
bad_pistol = BadPistol()
clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            exit()

    player.movement()
    bad_pistol.move()
    screen.fill(WHITE)
    screen.blit(player.current_picture, (player.x, player.y))
    screen.blit(bad_pistol.bad_pistol_pic, (bad_pistol.x, bad_pistol.y))

    pygame.display.flip()
    clock.tick(FPS)
