Create Music Player in Python with Output

In this article we will walk through process of Create Music Player in Python and Pygame module that can play only mp3 songs. Pygame is popular Python module used for building games and multimedia applications. It provides a set of tools and features that make it easy to develop games and multimedia applications in Python. In this tutorial we will leverage these features to create a simple music player that can play mp3 files.

Step 1: Importing Pygame and OS modules

The first step is import required modules – pygame and os. Pygame module will be used for playing music while os module is used to access the music directory and files.

import pygame
import os

Step 2: Initializing Pygame mixer

After importing module we initialize Pygame mixer module which provides set of functions to load, play and control music files.

pygame.init()
pygame.mixer.init()

Step 3: Setting up Pygame display module

To display music player window we set up Pygame display module and also set caption the window.

display = pygame.display.set_mode((600, 400))
pygame.display.set_caption('MP3 Music Player')

Step 4: Setting up font

We set font for text that will be displayed music player window.

font = pygame.font.SysFont('Arial', 25)

Step 5: Accessing music directory

We set path to music directory and use os module to get list of all the mp3 file in directory.

music_dir = 'path/to/music/folder'
songs = [song for song in os.listdir(music_dir) if song.endswith('.mp3')]

Step 6: Loading and playing first song

We set current_song variable to keep track of current song being played. Then we load and play first song in list.

current_song = 0
pygame.mixer.music.load(os.path.join(music_dir, songs[current_song]))
pygame.mixer.music.play()

Step 7: Setting up main loop

We set main loop that will handle events such as:
key presses
mouse clicks
We first get events using Pygame event module.

while True:
    events = pygame.event.get()

Step 8: Handling quit event

We check for quit event and exit program if user closes window.

for event in events:
    if event.type == pygame.QUIT:
        pygame.quit()
        exit()

Step 9: Handling key events

We check for key events, such as left and right arrow key presses play the previous or next song accordingly.

if event.type == pygame.KEYDOWN:
    if event.key == pygame.K_LEFT:
        current_song = (current_song - 1) % len(songs)
        pygame.mixer.music.load(os.path.join(music_dir, songs[current_song]))
        pygame.mixer.music.play()
    elif event.key == pygame.K_RIGHT:
        current_song = (current_song + 1) % len(songs)
        pygame.mixer.music.load(os.path.join(music_dir, songs[current_song]))
        pygame.mixer.music.play()

Step 10: Displaying current song name

We fill screen with black color and draw name of current song on screen using font we set up earlier.

display.fill((0, 0, 0))
text = font.render(songs[current_song], True, (255, 255, 255))
display.blit(text, (10, 

Complete code implementation

Here is complete code implementation for Music Player using Python:

import pygame
import os

pygame.init()

# set up the Pygame mixer module
pygame.mixer.init()

# set up the Pygame display module
display = pygame.display.set_mode((600, 400))
pygame.display.set_caption('MP3 Music Player')

# set up the font
font = pygame.font.SysFont('Arial', 25)

# set up the path to the music directory
music_dir = 'path/to/music/folder'

# get a list of all the mp3 files in the music directory
songs = [song for song in os.listdir(music_dir) if song.endswith('.mp3')]

# set up the current song index
current_song = 0

# load the first song in the list
pygame.mixer.music.load(os.path.join(music_dir, songs[current_song]))

# play the loaded song
pygame.mixer.music.play()

# set up the loop
while True:
    # get the events
    events = pygame.event.get()
    for event in events:
        # check for the quit event
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
        
        # check for key events
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                # play the previous song
                current_song = (current_song - 1) % len(songs)
                pygame.mixer.music.load(os.path.join(music_dir, songs[current_song]))
                pygame.mixer.music.play()
            elif event.key == pygame.K_RIGHT:
                # play the next song
                current_song = (current_song + 1) % len(songs)
                pygame.mixer.music.load(os.path.join(music_dir, songs[current_song]))
                pygame.mixer.music.play()
    
    # fill the screen with black color
    display.fill((0, 0, 0))
    
    # draw the current song name on the screen
    text = font.render(songs[current_song], True, (255, 255, 255))
    display.blit(text, (10, 10))
    
    # update the display
    pygame.display.update()
    
    # check if the current song has ended
    if not pygame.mixer.music.get_busy():
        # play the next song
        current_song = (current_song + 1) % len(songs)
        pygame.mixer.music.load(os.path.join(music_dir, songs[current_song]))
        pygame.mixer.music.play()
