Python – _tkinter. TclError : couldn’t open “sample.gif”: no such file or directory

Tkinter has a very strange problem.

I can usually display images on tkinter.
However, if I try to load a music file, I can’t display any image on it.

For example,

import tkinter as Tk

class Frame(Tk.Frame):

def __init__(self, master=None):
    Tk.Frame.__init__(self, master)

self.f = Tk.Frame(self)
    self.f.pack()

self. ARTWORK = ['guthrie.gif']

self.f_artwork = Tk.Frame(self.f)
    self.f_artwork.pack()
    self.artwork_img = Tk.PhotoImage(file=self. ARTWORK[0])

self.artwork_la = Tk.Label(self.f_artwork, image=self.artwork_img)
    self.artwork_la.pack()

if __name__ == '__main__':

f = Frame()
f.pack()
f.mainloop()

In this case I can display the image, however

import tkinter as Tk
import os
from tkinter.filedialog import askdirectory
import pygame

song_list = []

directory = askdirectory()
os.chdir(directory)

for file in os.listdir(directory):
    if file.endswith('.mp3'):
        realdir = os.path.realpath(file)
        song_list.append(file)

pygame.mixer.init()
    pygame.mixer.music.load(song_list[0])
    pygame.mixer.music.play()

pygame.mixer.init()
pygame.mixer.music.load(song_list[0])
pygame.mixer.music.play()

class Frame(Tk.Frame):

def __init__(self, master=None):
    Tk.Frame.__init__(self, master)

self.f = Tk.Frame(self)
    self.f.pack()

self. ARTWORK = ['guthrie.gif']

self.f_artwork = Tk.Frame(self.f)
    self.f_artwork.pack()
    self.artwork_img = Tk.PhotoImage(file=self. ARTWORK[0])

self.artwork_la = Tk.Label(self.f_artwork, image=self.artwork_img)
    self.artwork_la.pack()

if __name__ == '__maim__':

f = Frame()
f.pack()
f.mainloop()

For this program, I can’t display images on Tkinter.
The file is not recognized by Tkinter.
The error message is
_tkinter. TclError: Cannot open ‘guthrie.gif’: There is no such file or directory

Can you tell me what the reason is?
