python - 如何在 Tkinter 中设置 Entry 参数“显示”以始终在 Entry 字段中显示固定数量的星号？

问题描述

我将“显示”参数设置为“*”，这样“输入”字段就不会显示输入的内容。我遇到的问题是，它暗示了这个词的实际长度。因此，例如，如果我输入单词“blue”，它将显示为“****”，这暗示它是一个 4 个字符长的单词。此外，解决方案代码需要与填写上述字段的随机函数一起使用

我该如何解决这个简单的方法？

编辑：为了把事情放到一个上下文中，这是我制作的应用程序的代码。

import random
from tkinter import *

def num_guess():
    try:
        int(num_input.get())

    except ValueError:
        Ans = "You must enter a number in your number field!\n"
        result_field.insert(INSERT, Ans)

    if int(num_input.get()) == int(hidden_num):
        Ans = "Congrats you guessed correctly!\n"
        result_field.insert(INSERT, Ans)
        secret_num.delete(0, END)
        secret_num.insert(END, hidden_num) 

    elif int(num_input.get()) in range(int(hidden_num) - 2, int(hidden_num) + 3):
        Ans = "You are very close to secret number!..." + str(num_input.get()) + "\n"    
        result_field.insert(INSERT, Ans)

    elif int(num_input.get()) in range(int(hidden_num) - 5, int(hidden_num) + 6):
        Ans = "You are close to secret number!..." + str(num_input.get()) + "\n"    
        result_field.insert(INSERT, Ans)

    elif int(num_input.get()) in range(int(hidden_num) - 10, int(hidden_num) + 11):

        result_field.insert(INSERT, Ans)

    elif int(num_input.get()) in range(int(hidden_num) - 15, int(hidden_num) + 16):
