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。
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')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
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)
为了方便用户切换问题，在窗口上添加对应的按钮。
import pygame.font
class 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
