如何使用tkinter在python中选择多个文件或整个文件夹(显示它包含的所有文件的名称)？

import tkinter as tk
from tkinter import filedialog
import os

root = tk.Tk()
root.title("文件选择器")

def select_files():
    # 弹出文件选择对话框
    file_path = filedialog.askopenfilenames(initialdir="/", title="选择文件或文件夹")
    
    # 获取选择的文件或文件夹路径
    file_paths = root.tk.splitlist(file_path)
    
    # 显示选择的文件或文件夹名称
    for path in file_paths:
        if os.path.isdir(path):
            # 如果选择的是文件夹，则显示文件夹下所有文件的名称
            files = os.listdir(path)
            for file in files:
                print(file)
        else:
            # 如果选择的是文件，则直接显示文件名称
            print(os.path.basename(path))

select_button = tk.Button(root, text="选择文件或文件夹", command=select_files)
select_button.pack()

root.mainloop()

import tkinter as tk
from tkinter import filedialog
import os

def select_files():
    file_path = filedialog.askopenfilenames(initialdir="/", title="选择文件或文件夹")
    file_paths = root.tk.splitlist(file_path)
    for path in file_paths:
        if os.path.isdir(path):
            files = os.listdir(path)
            for file in files:
                print(file)
        else:
            print(os.path.basename(path))

root = tk.Tk()
root.title("文件选择器")

select_button = tk.Button(root, text="选择文件或文件夹", command=select_files)
select_button.pack()

root.mainloop()
