Python开发Hangman游戏：单词转下划线及大小写兼容问题求助

问题1：将目标单词转为下划线形式显示 #

你之前定义的underscoreWoord函数未被调用且逻辑有误，正确实现方式如下：

• 在GekozenMain中新增一个StringVar专门存储下划线格式的单词
• 绑定原单词变量的追踪事件，当原单词更新时自动生成下划线文本
• 将标签绑定到这个新的StringVar上

具体修改点：

1. 在GekozenMain的__init__方法中添加下划线变量：

self.underscore_var = tk.StringVar()

2. 编写更新下划线的函数并绑定追踪：

def update_underscore(*args):
    target_word = self.controller.shared_data["gekozenWoord"].get()
    # 字母替换为下划线，非字母保留原字符，用空格分隔
    underscore_text = ' '.join(['_' if c.isalpha() else c for c in target_word])
    self.underscore_var.set(underscore_text)

# 追踪原单词变化，自动更新下划线
self.controller.shared_data["gekozenWoord"].trace_add("write", update_underscore)

3. 修改标签绑定的变量为下划线变量：

woordLabel = tk.Label(self, textvariable=self.underscore_var, font=("futura"))

问题2：实现大小写不敏感的猜词判断 #

在RaadWoord方法中，将用户输入和目标单词统一转为小写（或大写）后再比较：

def RaadWoord(self):
    target_word = self.controller.shared_data["gekozenWoord"].get().lower()
    user_input = self.wentry.get().strip().lower()
    if user_input == target_word:
        tk.messagebox.showinfo("成功", "恭喜你猜对了！")
        self.AnderWoord()
    else:
        tk.messagebox.showwarning("错误", "猜错了，再试试！")
    self.wentry.delete(0, "end")

注：需导入tkinter.messagebox模块使用弹窗提示。
