千家信息网最后更新 2024年11月11日如何用Python实现问题回答小游戏

这篇文章将为大家详细讲解有关如何用Python实现问题回答小游戏，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。

读取问题

如下所示，我们在文本中写了一个问题，然后将其读取出来。

"黄河远上白云间，一片孤城万仞山。"的作者是谁？
王之涣
李白
白居易
杜甫

file = open("1.txt", "r")question_coll = file.readlines()file.close()print(file)

运行之后发现报错，查询之后发现编码格式不正确。

设置了读取的编码格式发现可以读取文本的内容

file = open("1.txt", encoding='utf-8')

绘制回答面板

为了方便读取，新建一个类来储存文件中的问题

# 问题类class Question:    # 回答列表    answer_question = []    # 正确答案    answer_index = 1    """问题类"""    def __init__(self, question):        self.question = question

导入问题，将文件中的问题保存在qustion中

from question import Question

因为文件的格式是固定的以6为一个问题的所有行数。

将问题

questionList = []for i in range(int(len(question_coll) / 6)):    que_all = question_coll[i * 6: i * 6 + 6]    que = Question(que_all[0].rstrip())    que.answer_question = [que_all[1].rstrip(), que_all[2].rstrip(), que_all[3].rstrip(), que_all[4].rstrip()]    que.answer_index = int(que_all[5].rstrip())    questionList.append(que)

封装屏幕上显示文字的打印

def draw_text(window_screen, font_size, content, starting_x, starting_y, text_color=WHITE, bg_color=BLACK):    # 绘制文字    # 设置字体    font = pygame.font.SysFont("方正粗黑宋简体", font_size)    text1 = font.render(content, True, text_color, bg_color)    window_screen.blit(text1, (starting_x, starting_y))

显示问题

draw_text(screen, 48, "知识竞赛", 180, 20)while True:    for event in pygame.event.get():        if event.type == QUIT:            pygame.quit()            sys.exit()    tips = "当前一共有" + str(len(questionList)) + "个问题,目前是第" + str(index) + "个。"    draw_text(screen, 18, tips, 20, 140, bg_color=WHITE, text_color=BLACK)    current_que = questionList[index - 1]    question_main = "问题" + str(index) + ". " + current_que.question    draw_text(screen, 16, question_main, 20, 200, bg_color=WHITE, text_color=BLACK)    for i in range(len(current_que.answer_question)):        option = str(i + 1) + ". " + current_que.answer_question[i]        draw_text(screen, 16, option, 40, 260 + i * 40, bg_color=WHITE, text_color=BLACK)    pygame.display.update()

这样就实现了问题的显示

回答问题

首先我们给出提示，为了方便确认问题是否回答，答案正确与否，我们在问题类中添加变量

# 是否回答    answeredFlg = False    # 回答是否正确    rightFlg = False

根据这些变量设置文字。

if current_que.answeredFlg:        if current_que.rightFlg:            print("回答正确，是" + current_que.answer_question[current_que.answer_index])        else:            print("回答错误，正确答案是" + current_que.answer_question[current_que.answer_index])    else:        draw_text(screen, 16, "请按下1、2、3、4来回答答案", 40, 460, bg_color=WHITE, text_color=RED)

如果按下按键，根据答案的正确与否给与响应的提示。

 if current_que.answeredFlg:        if current_que.rightFlg:            str1 = "回答正确，是" + current_que.answer_question[current_que.answer_index - 1]            draw_text(screen, 16, str1, 40, 460, bg_color=WHITE, text_color=GREEN)        else:            str1 = "回答错误，正确答案是" + current_que.answer_question[current_que.answer_index - 1]            draw_text(screen, 16, str1, 40, 460, bg_color=WHITE, text_color=RED)    else:        draw_text(screen, 16, "请按下1、2、3、4来回答答案", 40, 460, bg_color=WHITE, text_color=RED)

问题切换

为了方便用户切换问题，在窗口上添加对应的按钮。

import pygame.fontclass Button:    def __init__(self, screen, msg, start_x, start_y):        # 设置按钮的尺寸和其他属性        self.screen = screen        self.width, self.height = 200, 50        self.button_color = (0, 255, 0)        self.text_color = (255, 255, 255)        self.font = pygame.font.SysFont("方正粗黑宋简体", 20)        # 创建按钮的rect对象，并使其居中        self.rect = pygame.Rect(0, 0, self.width, self.height)        self.rect.left = start_x        self.rect.right = start_y        # 按钮的标签只需创建一次        self._prep_msg(msg)    def _prep_msg(self, msg):        """将msg渲染为图像，并让按钮居上"""        self.msg_image = self.font.render(msg, True, self.text_color, self.button_color)        self.msg_image_rect = self.msg_image.get_rect()        self.msg_image_rect.center = self.rect.center    def draw_button(self):        # 绘制一个用颜色填充的按钮，在绘制文本        self.screen.fill(self.button_color, self.rect)        self.screen.blit(self.msg_image, self.msg_image_rect)

answer_question.py

        btn1 = Button(screen, "next", 300, 500)    btn1.draw_button()

修改对应的按钮颜色，并添加上一个按钮。

通过是否回答和是否有下一个或者上一个控制按钮的显示

if current_que.answeredFlg and index < len(questionList):        btn1 = Button(screen, "下一个", 300, 500)        btn1.draw_button()    if index > 1:        btn2 = Button(screen, "上一个", 50, 500)        btn2.draw_button()

给按钮添加事件

if event.type == pygame.MOUSEBUTTONDOWN:            mouse_pos = pygame.mouse.get_pos()            if btn1.rect.collidepoint(mouse_pos):                if current_que.answeredFlg and index < len(questionList):                    index += 1            if btn2.rect.collidepoint(mouse_pos) and index > 1:                index -= 1
