仅在菜单中选择选项时才打开对话框

Question

我接受了一些项目，并将它们组合到一个菜单脚本中，您可以在其中选择要执行的操作，程序将相应运行。 当我在PyCharm IDE中运行它时，一切都很好，但是当我尝试从CMD（Windows 10）运行它时，即使没有/没有人要求它，对话框也会打开。

如果将root = tk.Tk（）放在类中，我会得到

  

RecursionError：调用Python对象时超出了最大递归深度

感谢您的帮助！ 代码：

import tkinter as tk
from tkinter import filedialog

class ShowFiles:

    root = tk.Tk()

    def __init__(self):
        self.path = path
        self.folder = folder
        self.filelocation = filelocation
        self.filenames = filenames
        self.root = root
        self.user = user
        self.root = root


        def show_files():

        try:
            # Opens a folder dialog box.
            path = filedialog.askdirectory(parent=root,
                                       initialdir=os.getcwd(),
                                       title="Select A Folder:")
            folder = path
            # User choose a filename to show on Desktop.
            savename = input("Name the file: ")
            filelocation = f"c:\\Users\\Gilush\\Desktop\\{savename}.txt"
            # Get the file names in the folder.
            filenames = os.listdir(folder)

            # Writing to file
            with open(filelocation, 'ab') as file:

                               f"######################################################\n".encode())

            print(colored(f"[+] Done! file {savename}.txt has been saved on your Desktop! [+] \n", 'cyan'))

            ShowFiles.restart()
