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？

Question

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，它暗示了单词的实际长度。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：将事物放入上下文中，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):
        Ans = "You are relatively close to secret number!..." + str(num_input.get()) + "\n"    
        result_field.insert(INSERT, Ans)

    elif int(num_input.get()) in range(int(hidden_num) - 15, int(hidden_num) + 16):
        Ans = "You are far from secret number!..." + str(num_input.get()) + "\n"   
        result_field.insert(INSERT, Ans)

    else:
        Ans = "You are very far from secret number!..." + str(num_input.get()) + "\n"   
        result_field.insert(INSERT, Ans)

    secret_num.insert(END, random.randint(1,100)) 
    hidden_num = secret_num.get()
    secret_num.delete(0, END)
    secret_num.insert(END, "***")
    result_field.insert(INSERT, "Now enter your number as a guess!\n")

hidden_num = 0

window.mainloop()

Answer 1

如何在 Tkinter 中设置 Entry 参数“show”以始终在 Entry 字段中显示固定数量的星号？ ..我该如何解决这个简单的方法？

没有简单的方法，也没有其他方法可以使用show 属性隐藏长度，而不是将显示设置为空白。

如果您需要更安全的东西，则必须创建自己的绑定，以接受来自用户的输入，然后显示其他内容。

Answer 2

使用此代码：

from tkinter import *
root = Tk()

passwordInput = Entry(root, show = "   ‍   ")
passwordInput.pack()

root.mainloop()

请务必仔细复制show = 中的代码。它与空白空间的长度不同，因此可以将人们赶走。将其复制到此处（引号之间）：“ ‍” 注意是iEmpty 空白字符

如果需要，可以将显示设置为：（只需空格键）
