I have the following code where I’m trying to allow the user to open a text file and once the user has selected it, I would like the code to read it (this isn’t a finished block of code, just to show what I’m after).
However, I’m having difficulties either using tkFileDialog.askopenfilename and adding ‘mode=’rb” or using the code like below and using read where it produces an error.
Does anyone know how I can arrange to do this as I don’t wish to have to type Tkinter.’module’ for each item such as Menu and Listbox. Beginner to Tkinter and a bit confused! Thanks for the help!
import sys from Tkinter import * import tkFileDialog from tkFileDialog import askopenfilename # Open dialog box fen1 = Tk() # Create window fen1.title("Optimisation") # menu1 = Menu(fen1) def open(): filename = askopenfilename(filetypes=[("Text files","*.txt")]) txt = filename.read() print txt filename.close() fen1.mainloop()
Obviously the error I’m getting here is:
AttributeError: 'unicode' object has no attribute 'read'
I don’t understand how to use the askopen and also be able to read the file I’m opening.

Answer
askopenfilename
only returns a file name, what you wanted was askopenfile
which accepts a mode
parameter and opens the file for you.
