学习python编写飞船入侵时提示Ship() takes no arguments

代码1

_import sys
import pygame
from settings import Settings
from ship import Ship

def run_game():
     #初始化Pygame、并设置和屏幕对象#
     pygame.init()
     ai_settings = S_ettings()
     screen = pygame.display.set_mode(
         (ai_settings.screen_wi_dth, ai_settings.screen_height))
     pygame.display.set_caption("Alien Invasion")

     #创建一艘飞船#
     ship = Ship(screen)
     # 开始游戏主循环#
     while True:
       for event in pygame.event.get():
         if event.type == pygame.QUIT:
             sys.exit()

       #每次循环时都重绘屏幕#
       screen.fill(ai_settings.bg_color)

       ship.blitme()
       #让最近绘制的屏幕可见#
       pygame.display.flip()

run_game()_

代码2

import pygame

class Ship():

      def __int__(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外接矩形#
          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 blitme(self):
          """在指定位置绘制飞船"""
          self.screen.blit(self.image, self.rect)

代码3.

class Settings():
    #储存《外星人入侵》的所有设置的类#
    def __init__(self):
       """初始化游戏设置"""
       self.screen_width = 1200
       self.screen_height = 800
       self.bg_color = (230, 230, 230)

运行alien_invasion.py 之后，出现全黑的窗口，然后窗口自动退出
请问什么问题呢？

下面是提示信息：

C:\Users\pc\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/pc/python_tool/alien_invasion/alien_invasion.py

ship = Ship(screen)

恳请大家指正

def __int__(self, screen):
改为
def __init__(self, screen):
你这不是构造函数，是随便取了个名字的函数，那么ship类使用默认构造函数，当然是无参数的了
