python使用tkinter实现自定义多参数对话框

import tkinter as tk
from tkinter.simpledialog import *
tk.Tk()     # 相当于开启Tkinter服务
askfloat("askfloat", "please input float")
# 3.1415926
askinteger("askinteger", "please input a integer number")
# 299732458
askstring("askstring", "please input string")
# 'tiny cool'

import tkinter as tk
import tkinter.ttk as ttk
class AskDct(tk.Tk):
    def __init__(self, dct):
        super().__init__()
        self.title("请输入参数")
        self.dct = dct
        self.initWidgets()
        self.mainloop()
    def initWidgets(self):
        self.varDct = {}
        for i,key in enumerate(self.dct):
            self.varDct[key] = tk.StringVar()
            frm = tk.Frame(self)
            frm.pack(side=tk.TOP)
            ttk.Label(frm, text=key, width=10).pack(side=tk.LEFT, pady=2)
            ttk.Entry(frm, width=20,
