Python：AttributeError：＆＃39;设置＆＃39;对象没有属性＆＃39; screen＆＃39;

Question

我遇到AttributeError问题：＆＃39;设置＆＃39;对象没有属性＆＃39; screen＆＃39;。请帮帮我，代码如下：

class Settings():
def __init__(self):
    self.screen_width=1200
    self.screen_height=800
    self.bg_color=(230,230,230)

import sys
import pygame
from settings import Settings
def run_game():
    pygame.init()
    ai_settings=Settings()
    screen=pygame.display.set_mode((ai_settings.screen_width,ai_settings.screen.height))
    pygame.display.set_caption("Inwazja obcych")
    while True:
        screen.fill(ai_settings.bg_color)
        for event in pygame.event.get():
            if event.type==pygame.quit:
                sys.exit()
    pygame.display.flip()


run_game()

它应该是screen_height的下划线。您的代码改为screen.height
