tkinter选择文件和目录（filedialog）

import tkinter as tk
from tkinter import filedialog

def open_file():
    # 弹出文件选择对话框并获取用户选择的文件路径
    file_path = filedialog.askopenfilename()
    if file_path:
        print("Selected file:", file_path)

def save_file():
    # 弹出文件保存对话框并获取用户选择的保存路径
    file_path = filedialog.asksaveasfilename()
    if file_path:
        print("Selected save path:", file_path)

def open_multiple_files():
    # 弹出文件选择对话框并获取用户选择的多个文件路径
    file_paths = filedialog.askopenfilenames()
    if file_paths:
        print("Selected files:", file_paths)

def choose_directory():
    # 弹出目录选择对话框并获取用户选择的目录路径
    directory_path = filedialog.askdirectory()
    if directory_path:
        print("Selected directory:", directory_path)

# 创建主窗口
root = tk.Tk()
root.title("File Dialog Example")

# 创建框架以容纳按钮，并设置左对齐
frame = tk.Frame(root)
frame.pack(padx=10, pady=10, anchor="w")

# 创建按钮并绑定事件，每个按钮调用相应的函数
btn_open_file = tk.Button(frame, text="Open File", command=open_file, width=20)
btn_open_file.pack(pady=5, anchor="w")

btn_save_file = tk.Button(frame, text="Save File", command=save_file, width=20)
btn_save_file.pack(pady=5, anchor="w")

btn_open_multiple_files = tk.Button(frame, text="Open Multiple Files", command=open_multiple_files, width=20)
btn_open_multiple_files.pack(pady=5, anchor="w")

btn_choose_directory = tk.Button(frame, text="Choose Directory", command=choose_directory, width=20)
btn_choose_directory.pack(pady=5, anchor="w")

# 运行主循环，使应用程序保持运行状态
root.mainloop()
