如何让用户使用python选择输出文件的路径

Question

我有一个python脚本，它读取文件并将其内容复制到另一个文件，同时在发送之前删除不需要的行。

问题是我想允许用户选择源文件和目标路径。

如何解决这个问题？

outputSortedFiles.py

#!/usr/bin/python

'''FUNCTION THAT READ SELECTE DFILE AND WRITE ITS 
   CONTENT TO SECOND FILE WITH DELETING
   TH EUNWANTED WORDS'''

import Tkinter
from os import listdir
from os.path import isfile
from os.path import join
import tkFileDialog
import os

def readWrite():
    unwanted = ['thumbnails', 'tyroi', 'cache', 'Total files', 'zeryit', 'Ringtones', 'iconRecv',
                'tubemate', 'ueventd', 'fstab', 'default', 'lpm']
    mypath = r"C:\Users\hHJE\Desktop/filesys" 
    Tkinter.Tk().withdraw()
    in_path = tkFileDialog.askopenfile(initialdir = mypath, filetypes=[('text files', ' TXT ')])    
    files = [f for f in listdir(mypath) if isfile(join(mypath, f))]
    for file in files:
        if file.split('.')[1] == 'txt':
            outputFileName = 'Sorted-' + file
            with open(mypath + outputFileName, 'w') as w:
                with open(mypath + '/' + file) as f:
                    for l in f:
                        if not True in [item in l for item in unwanted]:
                            w.write(l)
                            print ("
                                    *********************************\
                                        THE OUTPUT FILE IS READY\
                                    *********************************\
                                   ")
    in_path.close()
    if __name__== "__main__":
        readWrite()

您可以像使用TkFileDialog一样询问inputFiles：

outputpath = tkFileDialog.asksaveasfile()
