import pygame
import os
from tkinter import *
from tkinter import filedialog

• This first part of the code is just simply importing all the necessary tools such as the pygame library.

pygame.init()
os.environ['SDL_AUDIODRIVER'] = 'sdl2'

• This intilializes the pygame library for audio operations.
• sdl2 is the audio driver necessary in order to get audio. sdl2 can change based on what driver your system runs on.

root = Tk()
root.title("MP3 Player")

• This creates the main window for the MP3 player and sets the title of the window.

playlist = []

• This creates an empty list to store the paths of the songs.

def add_songs():
    songs = filedialog.askopenfilenames(filetypes=[("MP3 files", "*.mp3")])
    for song in songs:
        playlist.append(song)
        songs_listbox.insert(END, os.path.basename(song))

# Create a function to play the selected song
def play_song():
    global current_song
    current_song = playlistbox.curselection()[0]
    pygame.mixer.music.load(playlist[current_song])
    pygame.mixer.music.play()

# Create a function to stop the current song
def stop_song():
    pygame.mixer.music.stop()

# Create a function to pause the current song
def pause_song():
    pygame.mixer.music.pause()

# Create a function to resume the current song
def resume_song():
    pygame.mixer.music.unpause()

# Create a function to play the next song
def next_song():
    global current_song
    current_song += 1
    if current_song >= len(playlist):
        current_song = 0
    pygame.mixer.music.load(playlist[current_song])
    pygame.mixer.music.play()

# Create a function to play the previous song
def prev_song():
    global current_song
    current_song -= 1
    if current_song < 0:
        current_song = len(playlist) - 1
    pygame.mixer.music.load(playlist[current_song])
    pygame.mixer.music.play()

• add_songs(): This function opens a file dialog to select the MP3 files you would like you and adds their path to playlist. It will also display the file chosen
• play_song(): Plays the selected song from playlist
• stop_song(): Stops the song currently playing
• pause_song(): Pauses the currently playing song
• resume_song(): Resumes the song if paused
• next_song(): Skips to the next song in ‘playlist’ and plays it
• prev_song(): Goes back to the previous song in ‘playlist’ and plays it

add_button = ttk.Button(root, text="Add Songs", command=add_songs)
play_button = ttk.Button(root, text="Play", command=play_song)

...

songs_listbox = Listbox(root, selectmode=SINGLE, selectbackground="gray")
songs_listbox.config(bg="black", fg="white", selectforeground="white", selectbackground="gray")

• The various button widgets are created to be able to add, play, stop, resume, skip, and go back to the pervious song.
• ‘Listbox’ widget creates a display list of selected songs.

• The widgets are placed using the grid layout manager for better alignment.
• ‘song_listbox’ are packed into the main window and are organized in a vertical layout.

root.mainloop()

• This final line of code starts the main event look which keeps the application running and responsive to user interactions.
