Python Tkinter随机名字生成器点击按钮不刷新及分类选择问题

核心问题点 #

• 随机取值逻辑仅在程序启动时执行一次，点击生成按钮不会重新计算随机值
• 每次点击重复创建展示名称的Label控件，新旧内容堆叠无法看到更新
• 所有复选框共用同一个绑定变量，无法正确识别用户选中的分类
• 生成逻辑固定输出希腊神话分类名称，未关联勾选的分类配置

功能说明 #

• 支持同时勾选多个分类，生成时会从所有选中分类的名称池中随机取值
• 未勾选任何分类时默认从全部分类中随机取名字
• 每次点击生成按钮都会重新计算随机值，不会出现内容不更新的问题
• 补充了原代码缺失的罗马、俄罗斯分类名称库，可自行修改扩展
