Python打字练习

代码解析

导入模块和定义单词列表

import tkinter as tk
import randomsample_words = ["apple", "banana", "cherry", "date", "fig", "grape", "kiwi", "lemon", "mango", "orange", "papaya", "quince", "ugli", "vanilla", "yam"
]

• 导入'tkinter'库用于创建 GUI
• 导入'random'库用于随机选择单词 
• 定义'sample_words'列表包含游戏中可能出现的单词

TypingGame 类的初始化

class TypingGame:def __init__(self, root):self.root = rootself.root.title("打字练习")  # 修改窗口标题self.canvas = tk.Canvas(self.root, width=800, height=600, bg="white")self.canvas.pack()self.user_input = tk.StringVar()self.words = []self.labels = []self.word_y_positions = []self.speed = 2  # 掉落速度self.game_over = False  # 游戏状态self.create_widgets()self.new_round()

• 初始化游戏类，设置窗口标题和画布 
• 创建'user_input'变量用于存储用户输入
• 初始化'words'、'labels'和'word_y_positions'列表
• 设置'speed'变量控制单词下落速度
• 初始化'game_over'状态
• 调用'create_widgets'方法创建控件，并开始新一轮游戏

创建控件

    def create_widgets(self):self.entry = tk.Entry(self.root, textvariable=self.user_input, width=50)self.entry.pack(pady=10)self.entry.bind("<KeyRelease>", self.check_input)self.result_label = tk.Label(self.root, text="", wraplength=400)self.result_label.pack(pady=10)self.new_round_button = tk.Button(self.root, text="New Round", command=self.new_round)self.new_round_button.pack(pady=10)# 将输入法锁定为英语self.root.bind('<FocusIn>', self.set_english_input)

• 创建输入框、结果标签和新一轮按钮，并将它们放置在窗口中
• 绑定'KeyRelease'事件到'check_input'方法，监听用户输入
• 绑定'FocusIn'事件到'set_english_input'方法，以确保输入法锁定为英语

设置输入法为英语

    def set_english_input(self, event):self.root.tk.call('tk', 'scaling', 1.0)  # 假定的命令以确保输入法锁定为英语

• 绑定窗口获取焦点时设置输入法为英语

新一轮游戏

    def new_round(self):num_words = random.randint(1, 5)  # 随机选择1到5个单词self.words = random.sample(sample_words, num_words)  # 选择不重复的单词self.user_input.set("")self.result_label.config(text="")self.word_y_positions = [0 for _ in self.words]self.game_over = Falsefor label in self.labels:self.canvas.delete(label)self.labels = []used_positions = []for word in self.words:while True:x_position = random.randint(50, 750 - len(word) * 15)  # 确保单词不会超出边界y_position = 0if not any(abs(x_position - pos[0]) < len(word) * 15 and abs(y_position - pos[1]) < 30 for pos in used_positions):used_positions.append((x_position, y_position))breaklabel = self.canvas.create_text(x_position, y_position, text=word, font=("Helvetica", 24), fill="black")self.labels.append(label)self.entry.config(state='normal')self.entry.focus()self.drop_words()

• 随机选择1到5个不重复的单词
• 清空输入框和结果标签，重置单词位置和游戏状态
• 删除旧的标签并创建新的标签，确保单词不会重叠
• 调用'drop_words'方法开始单词下落

单词下落

    def drop_words(self):if not self.game_over:for i, label in enumerate(self.labels):self.word_y_positions[i] += self.speedself.canvas.coords(label, self.canvas.coords(label)[0], self.word_y_positions[i])if self.word_y_positions[i] >= 600:self.result_label.config(text=f"Game Over! The word was: {self.words[i]}")self.game_over = Trueself.entry.config(state='disabled')returnself.root.after(50, self.drop_words)

• 如果游戏未结束，所有单词按速度下落
• 如果单词下落超过画布高度，显示游戏结束信息并禁用输入框
• 使用'root.after'方法定时调用'drop_words'方法实现动画效果

检查用户输入

    def check_input(self, event):if self.game_over:returninput_text = self.user_input.get()for index, word in enumerate(self.words):if word.startswith(input_text):correct_text = ""for i, char in enumerate(input_text):if i < len(word) and char == word[i]:correct_text += charelse:breakremaining_text = word[len(correct_text):]self.canvas.itemconfig(self.labels[index], text=f"{correct_text}{remaining_text}")self.canvas.itemconfig(self.labels[index], fill="green" if correct_text else "black")else:self.canvas.itemconfig(self.labels[index], fill="black")if input_text == word:self.canvas.delete(self.labels[index])self.words.pop(index)self.labels.pop(index)self.word_y_positions.pop(index)self.user_input.set("")  # 清空输入框if not self.words:self.result_label.config(text="Correct! Starting new round...")self.new_round()return

• 如果游戏结束，直接返回
• 获取用户输入并遍历所有单词，检查输入是否与单词开头匹配
• 将匹配部分的单词变为绿色
• 如果用户输入完整单词，删除该单词并清空输入框
• 如果所有单词都被正确输入，开始新一轮游戏

主程序

if __name__ == "__main__":root = tk.Tk()game = TypingGame(root)root.mainloop()

• 创建主窗口并实例化'TypingGame'类
• 进入'tkinter'主循环，开始游戏
