Tkinter请求选择文件夹

from tkinter import *
from tkinter import filedialog

gui_win = Tk()
gui_win.geometry('400x200')
gui_win.grid_rowconfigure(0, weight = 1)
gui_win.grid_columnconfigure(0, weight = 1)

def directory():
    # get a directory path by user
    filepath=filedialog.askdirectory(initialdir=r"F:\python\pythonProject",
                                    title="Dialog box")
    label_path=Label(gui_win,text=filepath,font=('italic 14'))
    label_path.pack(pady=20)

dialog_btn = Button(gui_win, text='select directory', command = directory)
dialog_btn.pack()

gui_win.mainloop()
可以看出askdirectory直接返回选择的文件夹目录
