tkinter - Python Error: Couldn't read from RWops

Question

I'm trying to make a small music player with tkinter, and pygame, by loading a file and then playing it. Everything works fine if I place the file-name into

pygame.mixer.music.load('filename.mp3')

But if I try to open the file with

file = tkinter.filedialog.askopenfile()
pygame.mixer.music.load(file)

and I browse to the file and click open, I get an error which says

python.error: Couldn't read from RWops

Any clues onto what is causing this?

Answer 1

askopoenfile returns a handle to an open file. If you want a file name, call askopenfilename instead.
