python遇到错误AttributeError: 'Settings' object has no attribute 'screen_width'
AttributeError: 'Settings' object has no attribute 'screen_width'运行就出现，改了就会出现其他错误，各位大佬能帮忙看看吗？
class Settings():
"""存储《外星人入侵》的所有设置的类"""
def _init_(self):
"""初始化游戏的设置"""
#屏幕设置
self.screen_width = 1080
self.screen_height = 960
self.bg_color = (230, 230, 230)

import pygame
class Ship():
def _init_(self,screen):
"""初始化飞船并设置其初始位置"""
self.screen = screen
#加载飞船图像并获取其外链接矩形
self.image = pygame.image.load('images/ship.bmp')
self.rect = self.image.get_rect()
self.screen_rect = screen.get_rect()
#将每艘新飞船放在屏幕底部中央
self.rect.centerx = self.screen_rect.centerx
self.rect.bottom = self.screen_rect.bottom

def run_game():
#初始化游戏并创建一个屏幕对象
pygame.init()
ai_settings = Settings()
screen = pygame.display.set_mode(

pygame.display.set_caption("Alien Imvasion")
#创建一艘飞船
ship = Ship(screen)
#开始游戏的主循环
while True:
#监视键盘和鼠标事件
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
#每次循环都重绘屏幕
screen.fill(ai_settings.bg_color)
ship.blitme()
#让最近绘制的屏幕可见
pygame.display.flip()
run_game()

我有修改代码，只要不用前面两个就能跑
用了就报错，有大佬能说一下原因吗？
AttributeError: 'Settings' object has no attribute 'screen_width'
TypeError: Ship() takes no arguments 构造函数时双下划线开始双下划线结束 def __init__(self,screen):
