Overview
An overview of file dialogs:

Tkinter Open File

The askopenfilename function to creates an file dialog object. The extensions are shown in the bottom of the form (Files of type). The code below will simply show the dialog and return the filename. If a user presses cancel the filename is empty. On a Windows machine change the initialdir to “C:\”.

Python 2.7 version:

.asksaveasfilename	Directory, Title, Extension)	To save file: Dialog that requests creation or replacement of a file.
.askdirectory	None	To open directory

from Tkinter import *from Tkinter import * import Tkinter, Tkconstants, tkFileDialog root = Tk() root.filename = tkFileDialog.askopenfilename(initialdir = "/",title = "Select file",filetypes = (("jpeg files","*.jpg"),("all files","*.*"))) print (root.filename)

Python 3 version:

from tkinter import filedialog
from tkinter import *

root = Tk()
root.filename =  filedialog.askopenfilename(initialdir = "/",title = "Select file",filetypes = (("jpeg files","*.jpg"),("all files","*.*")))
