python利用文件对话框获取文件路径

一、单文件

python3：

 import tkinter as tk
 from tkinter import filedialog

 root = tk.Tk()
 root.withdraw()

 file_path = filedialog.askopenfilename()

python2：

 import Tkinter, tkFileDialog

 root = Tkinter.Tk()
 root.withdraw()

 file_path = tkFileDialog.askopenfilename()

二、多文件

 import tkinter as tk
 from tkinter import filedialog

 root = tk.Tk()
 root.withdraw()

 file_path = filedialog.askopenfilenames()
 for f in file_path:
     fo = f.split('.')[0]+'.csv'
     with open(fo,'w') as foo:
         with open(f,'r') as fn:
             fn.readline()
             for line in fn.readlines():
                 li = line.strip().split()
                 foo.write('%f,%f\n'%(float(li[1]),float(li[0])))
                 print(li)
