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
'%(float(li[1]),float(li[0])))
                print(li)
