【python入门】属性丢失？AttributeError: 'Scoreboard' object has no attribute 'level'

Question

运行提示：

    self.level.rect = self.level_image.get_rect()
AttributeError: 'Scoreboard' object has no attribute 'level'

这是我的scoreboard部分的代码

import pygame.font

class Scoreboard():
    def __init__(self, ai_settings, screen, stats):
        self.screen = screen
        self.screen_rect = screen.get_rect()
        self.ai_settings = ai_settings
        self.stats = stats
        self.text_color = (30, 30, 30)
        self.font = pygame.font.SysFont(None, 48)

        self.prep_score()
        self.prep_high_score()
        self.prep_level()

    def prep_score(self):
        """将得分转换为一幅渲染的画像"""
        round_score = int(round(self.stats.score, -1))
        score_str = "{:,}".format(round_score)
        self.score_image = self.font.render(score_str, True, self.text_color,
                                            self.ai_settings.bg_color)

        self.score_rect = self.score_image.get_rect()
        self.score_rect.right = self.screen_rect.right - 20
        self.score_rect.top = 20

    def prep_high_score(self):
        """将最高得分转换为渲染的图像"""
        high_score = int(round(self.stats.high_score, -1))
        high_score_str = "{:,}".format(high_score)
        self.high_score_image = self.font.render(high_score_str, True,
                                                 self.text_color, self.ai_settings.bg_color)

        self.high_score_rect = self.high_score_image.get_rect()
        self.high_score_rect.centerx = self.score_rect.centerx
        self.high_score_rect.top = self.score_rect.top

    def prep_level(self):
        """将等级转换为渲染的图像"""
        self.level_image = self.font.render(str(self.stats.level), True,
                self.text_color,self.ai_settings.bg_color)
        #将等级放在得分的下方
        self.level_rect = self.level_image.get_rect()
        self.level_rect.right = self.score_rect.right
        self.level_rect.top = self.score_rect.bottom + 10

    def show_score(self):
        self.screen.blit(self.score_image, self.score_rect)
        self.screen.blit(self.high_score_image, self.high_score_rect)
        self.screen.blit(self.level_image, self.level_rect)

各位，这是什么原因导致的呢
代码核对过了，没啥错误呀

你这个类没有level属性，把self.level.rect改成self.level_rect
