python-3.x - python3中的tkSimpleDialog用法

Question

我正在开发我的程序以使其符合 python3 标准，但它严重依赖 tkinter，而且我遇到了一些问题。

我已经更改了所有导入名称，因为其中许多已重命名（哪些 tkinter 模块在 Python 3 中被重命名？），但我该如何处理以下问题？

class PasswordDialog(tkSimpleDialog.Dialog):

我尝试将其更改为

class PasswordDialog(tkinter.simpledialog.dialog):

但它一直告诉我AttributeError: 'module' object has no attribute 'dialog'

（非）工作代码：

#!/usr/bin/python3

from tkinter import simpledialog

class PasswordDialog(simpledialog.Dialog):                 
    def body(self, master):
        Label(master, text="Password for file "+currentfn).grid(row=0, sticky=W)
        self.e1 = Entry(master,show='*')
        self.e1.grid(row=0, column=1)
        self.attributes("-topmost", True) 
        return self.e1 
    def apply(self):
        p = self.e1.get()
        self.result = p

结果：

AttributeError: 'module' object has no attribute 'Dialog'

在 Windows 10 机器上使用 Python 3.74。我按原样采用了您的代码，并刚刚定义了 currentfn，它对我有用。这是我的整个代码清单
