我正在嘗試使用 Tkinter 編寫一個模擬 Hangman 游戲的 GUI。到目前為止，我已經(jīng)讓 GUI 創(chuàng)建了一個標簽，該標簽根據(jù)用戶正確猜測的字母進行更新，但終端仍然給出錯誤：“TypeError：‘StringVar’類型的參數(shù)不可迭代”。我已經(jīng)查看了此錯誤的其他解決方案，但無法弄清楚如何解決該問題。它還沒有完成 - 但到目前為止的代碼如下：import randomword# from PyDictionary import PyDictionaryfrom tkinter import *root = Tk()playerWord: str = randomword.get_random_word()word_guess: str = ''guesses = ''def returnEntry(arg=None):    global word_guess    global guesses    global wordLabel    word_guess = ''    # dictionary = PyDictionary()    failed = 0    incorrect = 10    result = myEntry.get()    while incorrect > 0:        if not result.isalpha():            resultLabel.config(text="that's not a letter")        elif len(result) != 1:            resultLabel.config(text="that's not a letter")        else:            resultLabel.config(text=result)            assert isinstance(END, object)            myEntry.delete(0, END)        guesses += result        for char in playerWord:            if char in guesses:                # Print the letter they guessed                word_guess += char            elif char not in guesses:                # Print "_" for every letter they haven't guessed                word_guess += "_ "                failed += 1        if guesses[len(guesses) - 1] not in playerWord:            resultLabel.config(text="wrong")            incorrect -= 1        wordLabel = Label(root, updateLabel(word_guess))        myEntry.delete(0, END)resultLabel = Label(root, text="")resultLabel.pack(fill=X)myEntry = Entry(root, width=20)myEntry.focus()myEntry.bind("<Return>", returnEntry)myEntry.pack()text = StringVar()text.set("your word is: " + ("_ " * len(playerWord)))wordLabel = Label(root, textvariable=text)wordLabel.pack()def updateLabel(word):    text.set("your word is: " + word)    return textmainloop()當我在 wordLabel 上運行該函數(shù)時出現(xiàn)問題：“wordLabel = Label(root, updateLabel(word_guess))”來重置標簽。關(guān)于如何在 while 循環(huán)迭代后將標簽更新為 word_guess 有什么建議嗎？
