Python -类-函数参数-takes 0 positional arguments but 1 was given

在学习 Python 基础的时候，在创建某一个 shownametest()函数，解析器会报错 ‘’‘ ypeError: shownametest() takes 0 positional arguments but 1 was given ’‘’ ‘’‘ import pygame

from settings import Settings

from ship import Ship import game_functions as gf from pygame.sprite import Group

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( (ai_settings.screen_width, ai_settings.screen_htight)) pygame.display.set_caption("Alien Invasion")

#创建一艘飞船
ship = Ship(ai_settings, screen)

#创建一个用于存储子弹的编组
bullets = Group()

#设置背景色
bg_color = (230, 230, 230)


#开始游戏的主循环
while True:
    gf.check_events(ai_settings, screen, ship, bullets)
    ship.update()
    gf.update_bullets(bullets)
    gf.update_screen(ai_settings, screen, ship, bullets)

    #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()
