无法将 python GUI 拆分为多个字段“AttributeError: module 'tk' has no attribute 'Frame'”

Question

我开始使用 Python，我对它还很陌生，所以我试图让我的主文件与其他页面一起在单独的 python 文件中运行。我不断收到同样的错误。

import tkinter as tk
from tkinter import *
from tkinter import ttk

import options as options

from StartPage import StartPage
from PageDecryption import Page2, Page2a, Page2b, Page2c
from PageEncryption import Page1, Page1a, Page1b, Page1c

LARGEFONT = ("Verdana", 35)



class tkinterApp(tk.Tk):

    # __init__ function for class tkinterApp
    def __init__(self, *args, **kwargs):
        # __init__ function for class Tk
        tk.Tk.__init__(self, *args, **kwargs)

        # creating a container
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        # initializing frames to an empty array
        self.frames = {}

        # iterating through a tuple consisting
        # of the different page layouts
        for F in (StartPage, Page1, Page2, Page1a, Page1b, Page1c, Page2a, Page2b, Page2c):
            frame = F(container, self)

            # initializing frame of that object from
            # startpage, page1, page2 respectively with
            # for loop
            self.frames[F] = frame

            frame.grid(row=0, column=0, sticky="nsew")

        self.show_frame(StartPage)

    # to display the current frame passed as
    # parameter
    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()





# Driver Code
app = tkinterApp()
app.mainloop()


import tk as tk
from tkinter import ttk
import tkinter
import StartPage

LARGEFONT = ("Verdana", 35)

class Page2(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = ttk.Label(self, text="Decryption", font=LARGEFONT)
        label.grid(row=0, column=4, padx=10, pady=10)

        # button to show frame 2 with text
        # layout2
        #button2 = ttk.Button(self, text="Encryption",
        #                     command=lambda: controller.show_frame(Page1))

        # putting the button in its place by
        # using grid
        #button2.grid(row=1, column=1, padx=10, pady=10)

        # button to show frame 3 with text
        # layout3
        button2 = ttk.Button(self, text="Startpage",
                             command=lambda: controller.show_frame(StartPage))

        # putting the button in its place by
        # using grid
        button2.grid(row=2, column=1, padx=10, pady=10)

        button2a = ttk.Button(self, text="Caeser",
                              command=lambda: controller.show_frame(Page2a))

        # putting the button in its place by
        # using grid
        button2a.grid(row=4, column=4, padx=10, pady=10)

        button2b = ttk.Button(self, text="Rail Method",
                              command=lambda: controller.show_frame(Page2b))

        # putting the button in its place by
        # using grid
        button2b.grid(row=2, column=4, padx=10, pady=10)

        button2c = ttk.Button(self, text="Blowfish",
                              command=lambda: controller.show_frame(Page2c))

        # putting the button in its place by
        # using grid
        button2c.grid(row=2, column=5, padx=10, pady=10)

我试图将文件拆分为多个文件以便于阅读，但我一直运行到模块“tk”没有属性“Frame”错误
