from tkinter import *
from tkinter.filedialog import askdirectory

def selectPath():
  path_ = askdirectory()
  path.set(path_)

root = Tk()

Label(root,text = "目标路径:").grid(row = 0, column = 0)
Entry(root, textvariable = path).grid(row = 0, column = 1)
Button(root, text = "路径选择", command = selectPath).grid(row = 0, column = 2)
