How to Create an MP3 Music Player in Python

Learn How to Create an MP3 Music Player in Python

Everybody loves listening to music wouldn’t it be cool to have our very own mp3 music player? So, in this python project, we are going to create an mp3 player with the help of python and its libraries. Let’s start the python mp3 player project. 

Python MP3 Music Player

We will create an mp3 music player in which we can play the song, pause it, resume it, and navigate from the current song to the next song as well as previous songs.

Next, we will be using the mixer module of a very famous python library called Pygame.

Pygame is basically used to create video games, it includes computer graphics and sound libraries. Mixer is one such sound library. Then, we will use the os library of python to interact with the Operating system.

Project Prerequisites

To work on Python mp3 player basic understanding of python programming language, Tkinter, and mixer module of pygame would be helpful.

A basic understanding of Tkinter widgets would also be required, but don’t worry as we will be explaining every line of code as we go developing this mp3 player project.

We will be using Python and its libraries. The first library that we will be using is Tkinter which is a widely used GUI library offered by python, we do not have to install it separately, as it comes with python itself.

Unlike the Tkinter library, we are required to install the Pygame library.

Please run the following command in your command prompt or terminal to install pygame.

pip install pygame

Download Python MP3 Player Project

Please download the source code of the python mp3 player: MP3 Music Player Python Code

After doing this we are all set to start this python project, you can use any IDE of your choice.

Steps to develop this project

1. Import important libraries
2. Create the project layout
3. Define play, pause, and other music player functions

1. Import important libraries

#importing libraries 

from pygame import mixer

from Tkinter import *

import Tkinter.font as font

from Tkinter import filedialog

Explanation:

• The first line imports the mixer module from pygame, and then we import Tkinter.
• Next, we import the font module from the Tkinter library. At last, filedialog is imported which has many applications like opening a file, a directory, etc.

2. Create the overall layout of python mp3 player

#creating the root window 

root=Tk()

root.title('Walker Python MP3 Music player App ')

#initialize mixer 

mixer.init()

#create the listbox to contain songs

songs_list=Listbox(root,selectmode=SINGLE,bg="black",fg="white",font=('arial',15),height=12,width=47,selectbackground="gray",selectforeground="black")

songs_list.grid(columnspan=9)

#font is defined which is to be used for the button font 

defined_font = font.Font(family='Helvetica')

#play button

play_button=Button(root,text="Play",width =7,command=Play)

play_button['font']=defined_font

play_button.grid(row=1,column=0)

#pause button 

pause_button=Button(root,text="Pause",width =7,command=Pause)

pause_button['font']=defined_font

pause_button.grid(row=1,column=1)

#stop button

stop_button=Button(root,text="Stop",width =7,command=Stop)

stop_button['font']=defined_font

stop_button.grid(row=1,column=2)

#resume button

Resume_button=Button(root,text="Resume",width =7,command=Resume)

Resume_button['font']=defined_font

Resume_button.grid(row=1,column=3)

#previous button

previous_button=Button(root,text="Prev",width =7,command=Previous)

previous_button['font']=defined_font

previous_button.grid(row=1,column=4)

#nextbutton

next_button=Button(root,text="Next",width =7,command=Next)

next_button['font']=defined_font

next_button.grid(row=1,column=5)

#menu 

my_menu=Menu(root)

root.config(menu=my_menu)

add_song_menu=Menu(my_menu)

my_menu.add_cascade(label="Menu",menu=add_song_menu)

add_song_menu.add_command(label="Add songs",command=addsongs)

add_song_menu.add_command(label="Delete song",command=deletesong)

mainloop()

Explanation

• Tk() is a top-level widget that is used to create the main application window in which we will be building our python project.
• The title() method is used to give a name to python mp3 player application which is displayed at the top.
• mixer.init() is used to initialize the mixer module so that we can use its various functions in our application.
• Listbox() widget is used to create a listbox in which we will store our songs.

1. We have passed various parameters, first is the root specifying that the widget should be placed in the python mp3 player window.
2. Then, bg is for background color, fg is for foreground color.
3. selectbackground and selectforeground basically change the background and the foreground color of a particular item upon selecting it.

• grid() widget is a geometry manager which organizes the widgets properly in a grid-based fashion before placing it in the root window. columnspan=9 gives a space of 9 columns to our listbox widget.
• Button() widget is used to create a button. We want the buttons in our main window so the input root is given. Then the text which will be displayed on the button is specified and at last in the command input, a function is given which will be called when the button is clicked.
• Menu() widget is displayed just under the title bar, it is used to conveniently access various operations. We are going to access Add songs and Delete songs for our playlist, upon clicking addsongs and deletesong functions are called respectively.

3. Create music player functions

#add many songs to the playlist of python mp3 player

def addsongs():

    #to open a file  

    temp_song=filedialog.askopenfilenames(initialdir="Music/",title="Choose a song", filetypes=(("mp3 Files","*.mp3"),))

##loop through every item in the list to insert in the listbox

for s in temp_song:

s=s.replace("C:/Users/Walker/python-mp3-music-player/","")

songs_list.insert(END,s)

def deletesong():

    curr_song=songs_list.curselection()

    songs_list.delete(curr_song[0])

  

def Play():

    song=songs_list.get(ACTIVE)

    song=f'C:/Users/lenovo/Desktop/Walker/Notepad/Music/{song}'

    mixer.music.load(song)

    mixer.music.play()

#to pause the song 

def Pause():

    mixer.music.pause()

#to stop the song 

def Stop():

    mixer.music.stop()

    songs_list.selection_clear(ACTIVE)

#to resume the song

def Resume():

    mixer.music.unpause()

#Function to navigate from the current song

def Previous():

    #to get the selected song index

    previous_one=songs_list.curselection()

    #to get the previous song index

    previous_one=previous_one[0]-1

    #to get the previous song

    temp2=songs_list.get(previous_one)

   temp2=f'C:/Users/Walker/python-mp3-music-player/{temp2}'

    mixer.music.load(temp2)

    mixer.music.play()

    songs_list.selection_clear(0,END)

    #activate new song

    songs_list.activate(previous_one)

    #set the next song

    songs_list.selection_set(previous_one)

def Next():

    #to get the selected song index

    next_one=songs_list.curselection()

    #to get the next song index

    next_one=next_one[0]+1

    #to get the next song 

    temp=songs_list.get(next_one)

  temp=f'C:/Users/Walker/python-mp3-music-player/{temp}'

    mixer.music.load(temp)

    mixer.music.play()

    songs_list.selection_clear(0,END)

    #activate newsong

    songs_list.activate(next_one)

     #set the next song

    songs_list.selection_set(next_one)

Explanation

• addsongs() is used to add songs in our listbox, filedialog.askopenfilenames() opens a dialog box corresponding to the folder whose path is provided. Then, we can select songs and store them in temp_song variable, after this we loop through the list to insert every item in the listbox.
• deletesong() is used to delete a selected song, songs_list.curselection() function returns a tuple in which the first element is the index of the selected song. Then, .delete() function is used to delete the song corresponding to the index which is passed.
• Play() function is used to play the selected song, we use the .get() method to get the selected song, then we load the song and play it using the next two lines.
• Pause() function is used to pause the song, we do not need to pass any argument to the mixer.music.pause() function.
• Stop() function is used to stop the song, we use mixer.music.stop() function to stop the song.

songs_list.selection_clear(ACTIVE) is used to unselect the selected song from the listbox

• Resume() function is used to resume the song using mixer.music.unpause() function.
• Previous() function is used to play the previous song in the listbox, songs_list.curselection() function returns a tuple in which the first element is the index of the selected song in python mp3 music player project. We store it in a variable called previous_one, then we update its value to get the previous index by subtracting 1. Next, songs_list.get(previous_one) returns the previous song, we store this value in temp2 after that we load this song and play it.

We would face a problem here, although the previous song would start playing, but the selected song would not change. So, we rectify that with the help of the next three lines of code.

• Next() function is implemented in a similar way as the previous function. Here, instead of subtracting 1, we add 1 apart from this step every other step is the same.

Python MP3 Music Player Output

Summary

Congratulations! We have successfully created python mp3 music player, and now we don’t have to rely on any other app.

Through this python project, we learned a lot of things about python and its libraries, the first one being the Tkinter library, a widely-used GUI library and various widgets that it offers, then the important mixer module of the pygame library which is used to manipulate the music.
