Trivia类编程存在的一些问题

Question

询问一下，关于readlines()函数怎么使用才不会使得输出到窗口上的内容是白板？编码是同类型，一样为”GBK“，是在做Trivia类遇到的难题

import pygame
import sys
from pygame.locals import *


def print_text(font, x, y, text, color=(255, 255, 255), shadow=True):
    if shadow:
        imgText = font.render(text, True, (0, 0, 0))
        screen.blit(imgText, (x - 2, y - 2))
    imgText = font.render(text, True, color)
    screen.blit(imgText, (x, y))

运行情况：

编码一致，但是原文本有中文，然后输出变成这样的情况

问题：关于readlines()函数怎么使用才不会使得输出到窗口上的内容是白板？ 回答： readlines()函数将文件的所有行读取到一个列表中，并将列表返回。在本例中，readlines()函数被用于从文件中读取Trivia游戏的问题和答案。 如果输出到窗口上的内容是白板，问题可能是出在以下几个方面： 1.文件编码问题：请确保文件和Python脚本的编码类型相同。可以使用Notepad++等编辑器查看文件的编码类型。在打开文件时，请指定文件的编码类型。 with open("demo_text.txt", "r", encoding='gbk') as f:

trivia_data = f.readlines()
f.close()

2.代码逻辑问题：请检查代码逻辑。在此例中，show_question()方法和next_question()方法用于显示问题和处理下一个问题。如果这两个方法的逻辑出现问题，可能会导致输出的内容为空白。 3.屏幕更新问题：请确保在输出后更新了屏幕。在每次输出后，使用pygame.display.update()方法更新屏幕。 下面是一个完整的示例代码，其中readlines()函数用于读取文件： import pygame from pygame.locals import * pygame.init() screen = pygame.display.set_mode((640, 480)) font1 = pygame.font.Font(None, 36) font2 = pygame.font.Font(None, 24) white = (255, 255, 255) yellow = (255, 255, 0) purple = (255, 0, 255) green = (0, 255, 0) red = (255, 0, 0) class Trivia(object): def init(self, filename): self.data = [] self.current = 0 self.total = 0 self.correct = 0 self.score = 0 self.scored = False self.failed = False self.wronganswer = 0 self.colors = [white, white, white, white] with open("demo_text.txt", "r", encoding='gbk') as f: trivia_data = f.readlines() f.close() for text_line in trivia_data: self.data.append(text_line.strip()) self.total += 1 def show_question(self): print_text(font1, 210, 5, "TRIVIA GAME") print_text(font2, 190, 500 - 20, "Press Keys(1-4) TO Answer", purple) print_text(font2, 530, 5, "SCORE", purple) print_text(font2, 550, 25, str(self.score), purple) self.correct = int(self.data[self.current + 5]) question = int(self.current / 6) print_text(font1, 5, 80, "QUESTION" + str(question + 1)) print_text(font2, 20, 120, self.data[self.current], yellow) if self.scored: self.colors = [white, white, white, white] self.colors[self.correct - 1] = green print_text(font1, 230, 380, "CORRECT!", green) print_text(font2, 170, 420, "Press Enter For Next Question", green) elif self.failed: self.colors = [white, white, white, white] self.colors[self.wronganswer - 1] = red self.colors[self.correct - 1] = green print_text(font1, 220, 380, "INCORRECT!", red) print_text(font2, 170, 420, "Press Enter For Next Question", red) # 显示答案 print_text(font1, 5, 170, "Answers") print_text(font2, 20, 210, "1 - " + self.data[self.current + 1], self.colors[0]) print_text(font2, 20, 240, "2 - " + self.data[self.current + 2], self.colors[1]) print_text(font2, 20, 270, "3 - " + self.data[self.current + 3], self.colors[2]) print_text(font2, 20, 300, "4 - " + self.data[self.current + 4], self.colors[3]) def next_question(self): if self.scored or self.failed: self.scored = False self.failed = False self.correct = 0 self.colors = [white, white, white, white] self.current += 6 if self.current >= self.total: self.current = 0 def handle_input(self, number): if not self.scored and not self.failed: if number == self.correct: self.scored = True self.score += 1 else: self.failed = True self.wronganswer = number def print_text(font, x, y, text, color=(255, 255, 255), shadow=True): if shadow: imgText = font.render(text, True, (0, 0, 0)) screen.blit(imgText, (x - 2, y - 2)) imgText = font.render(text, True, color) screen.blit(imgText, (x, y)) if name == 'main': trivia = Trivia("demo_text.txt") pygame.display.set_caption("Trivia Game") while True: for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() elif event.type == KEYUP: if event.key == pygame.K_ESCAPE: pygame.quit() sys.exit() elif event.key == pygame.K_RETURN: trivia.next_question() elif event.key == pygame.K_1: trivia.handle_input(1) elif event.key == pygame.K_2: trivia.handle_input(2) elif event.key == pygame.K_3: trivia.handle_input(3) elif event.key == pygame.K_4: trivia.handle_input(4) screen.fill((0, 0, 200)) trivia.show_question() pygame.display.update()
