使用GUI python浏览要打开和运行的文件

Question

嗨，我有一些python脚本。我需要用几个按钮创建一个GUI，通过浏览打开那些文件。我必须通过单击GUI按钮来运行这些脚本，并将输出写入一个n excel表。我试过下面的代码，但用它我可以读取文件！请帮忙？ 谢谢你

from Tkinter import *            
from tkFileDialog   
import askopenfilename      

def callback():
    r = open(askopenfilename(),'r')

a = Button(text='click me', command=callback)
a.pack()

mainloop()

        import Tkinter, tkFileDialog
        root = Tkinter.Tk()
        root.withdraw()
        dirname=tkFileDialog.askdirectory(parent=root,initialdir="/",title='Please select a directory')
        do something with dirname
        print dirname

#This code for file selection:

    from Tkinter import Tk
    from tkFileDialog import askopenfilename

    Tk().withdraw() # we don't want a full GUI, so keep the root window from appearing

    filename = askopenfilename() # show an "Open" dialog box and return the path to the selected file
    print(filename)
