使用Python实现单词记忆软件

前言

该代码实现了一个基于PyQt5的单词记忆软件，支持高考、四级、六级和考研四个级别的词库。程序提供四种学习模式：拆分模式（将单词拆分为片段重组）、填空模式（选择正确字母填空）、输入模式（手动输入单词）和测试模式（评估单词记忆效果）。软件界面包含单词释义显示、交互练习区域和反馈功能，支持单词级别切换、结果统计和保存功能。采用随机算法打乱单词顺序，确保学习效果，具有错误提示和自动跳转下一题功能，适合不同英语水平的学习者使用。 

目前存在的问题和优化思路，目前还没实现：

• 拆分模式再次点击已经被选择的单词片段可以取消锁定，但是要按单词拼写的倒序取消（原本是没锁定的，但是那样会导致一个字符可以重复点击，导致单词拼接不正确，而且还没法判断正误）。
• 模式之间切换会导致窗口卡死，这个还没找到是什么原因。
• 测试模式可以结合其他三种模式来进行选择。
• 当保存的时候点击那个词书就会保存什么，比如我是测试的“高考”，但是在保存的时候点击了“考研”，保存名字默认是“考研”。
• 单词太少了，完全是deepseek生成的，自己目前还没看到错误的，也可以是因为本人英语不好所以还没发现。

拆分模式

1. 显示单词的释义
2. 将单词拆分成若干片段并打乱顺序显示
3. 用户按正确顺序点击片段拼出完整单词
4. 系统检查是否正确，提供反馈

def setup_mode1(self, word, meaning):"""设置拆分模式"""self.mode1_meaning.setText(meaning)self.mode1_answer.clear()self.mode1_feedback.clear()# 清理旧按钮while self.mode1_chunks_layout.count():item = self.mode1_chunks_layout.takeAt(0)if item.widget():item.widget().deleteLater()# 安全拆分单词if len(word) < 2:chunks = [word]else:n = min(3, max(2, len(word) // 2))split_points = sorted(random.sample(range(1, len(word)), n - 1))chunks = []start = 0for point in split_points:chunks.append(word[start:point])start = pointchunks.append(word[start:])# 打乱顺序random.shuffle(chunks)# 创建新按钮self.chunk_buttons = []self.selected_chunks = []  # 存储字典：{"chunk": 片段, "button": 按钮, "position": 位置}for chunk in chunks:btn = QPushButton(chunk)btn.setStyleSheet("...")btn.clicked.connect(lambda _, c=chunk, b=btn: self.toggle_chunk(c, b))self.mode1_chunks_layout.addWidget(btn)self.chunk_buttons.append(btn)self.correct_word = wordself.user_answer = ""

填空模式

1. 显示单词的释义
2. 显示带有空缺的单词（部分字母被下划线替代）
3. 提供4个选项（1个正确，3个干扰项）
4. 用户选择正确选项填补空缺
5. 系统检查是否正确，提供反馈

def setup_mode2(self, word, meaning):"""设置填空模式"""self.mode2_meaning.setText(meaning)self.mode2_feedback.clear()# 清理旧选项while self.mode2_options_layout.count():item = self.mode2_options_layout.takeAt(0)widget = item.widget()if widget is not None:widget.deleteLater()del item# 创建填空if len(word) <= 3:blank_pos = len(word) // 2blank_len = len(word) - blank_poscorrect_part = word[blank_pos:]else:blank_len = min(3, max(2, len(word) // 3))blank_pos = random.randint(1, len(word) - blank_len - 1)correct_part = word[blank_pos:blank_pos + blank_len]blank_word = word[:blank_pos] + "_" * blank_len + word[blank_pos + blank_len:]self.mode2_blank.setText(blank_word)# 生成选项options = [correct_part]chars = list(set(word) - set(correct_part))while len(options) < 4:if chars:option = ''.join(random.sample(chars, min(len(chars), blank_len)))else:option = ''.join(random.choices('abcdefghijklmnopqrstuvwxyz', k=blank_len))if option != correct_part and option not in options:options.append(option)random.shuffle(options)# 创建选项按钮self.option_buttons = []  # 保存按钮引用防止被垃圾回收for option in options:btn = QPushButton(option)btn.setStyleSheet("...")btn.clicked.connect(lambda _, o=option, cp=correct_part, w=word: self.check_fill_answer(o, cp, w))self.mode2_options_layout.addWidget(btn)self.option_buttons.append(btn)  # 保存按钮引用

输入模式

这个当时最大的问题就是那个错误信息和文本信息没有清空，导致再次输入还可以看到提示信息，那岂不是可以照着输入。

1. 显示单词的释义
2. 用户输入框中输入对应单词
3. 系统检查是否正确，提供反馈
4. 可回车提交答案

def setup_mode3(self, meaning):"""设置输入模式"""self.mode3_meaning.setText(meaning)self.mode3_input.clear()self.mode3_feedback.clear()self.mode3_input.setFocus()self.input_error_shown = Falsedef check_input_mode(self):"""检查输入模式答案"""user_input = self.mode3_input.text().strip().lower()correct = self.current_words[self.current_index]["word"].lower()if user_input == correct:self.mode3_feedback.setText("✓ 正确！")self.mode3_feedback.setStyleSheet("color: #28a745;")QTimer.singleShot(1000, self.next_word)else:self.mode3_feedback.setText(f"✗ 错误！正确答案是: {correct}")self.mode3_feedback.setStyleSheet("color: #dc3545;")self.input_error_shown = True

测试模式

1. 点击"开始测试"按钮
2. 系统随机选择词库中的单词
3. 显示单词释义，用户输入对应单词
4. 记录错误次数
5. 测试完成后显示统计结果（正确率、错误最多的单词等）
6. 可保存测试结果到文件
