Python Kivy How to Play Mp3 Music

In this Python Kivy article we are going to learn How to Play Mp3 Music in Kivy, so for this

we need to use SoundLoader class from kivy.core.audio.

Also if you are interested in Python GUI Development with different libraries, you

can check the below links.

2: Pyside2 GUI Development Tutorials

3: wxPython GUI Development Tutorials

4: TKinter GUI Development Tutorials

Also you can watch the complete video for this article

We are going to create two examples, the first one will be an easy example, the second will be

a little complex example. this is the first example code.

Source code for Python Kivy How to Play Mp3 Music

from kivy.app import App
from kivy.core.audio import SoundLoader
from kivy.uix.label import Label



#our main window class 
class MusicWindow(App):

    def build(self):
        
        #load the mp3 music 
        music = SoundLoader.load('music.mp3')

        #check the exisitence of the music 
        if music:
            music.play()

        return Label(text = "Music is playing")





if __name__ == "__main__":
    window = MusicWindow()
    window.run()

from kivy.app import App

from kivy.core.audio import SoundLoader

from kivy.uix.label import Label

#our main window class

class MusicWindow(App):

def build(self):

#load the mp3 music

music = SoundLoader.load('music.mp3')

#check the exisitence of the music

if music:

music.play()

return Label(text = "Music is playing")

if __name__ == "__main__":

window = MusicWindow()

window.run()

These are the imports that we have used in the above code, you can see that we have imported

the SoundLoader class from kivy.core.audio module.

from kivy.app import App
from kivy.core.audio import SoundLoader
from kivy.uix.label import Label

from kivy.app import App

from kivy.core.audio import SoundLoader

from kivy.uix.label import Label

In this line of code we have loaded our Mp3 music, make sure that you have added an Mp3

sound in your working directory, as i have already added the mp3 sound.

 music = SoundLoader.load('music.mp3')

1	music = SoundLoader.load('music.mp3')

If you run the code you will see the music is playing.

Now let’s create the second example, in this example we are going to create a button using our

kivy file, and after that we want when a user clicks on the button, we want to play mp3 music.

So first create a python file, iam going to call it kivymusicapp.py, you can see that the first class extends from the FloatLayout, also we have added a method in this class for loading and playing our mp3 sound, because we will connect this method with the button that we create in the .kv file.

from kivy.app import App
from kivy.core.audio import SoundLoader
from kivy.uix.floatlayout import FloatLayout



class MyFloatLayout(FloatLayout):


    def play_music(self):
        music = SoundLoader.load('music.mp3')

        if music:
            music.play()




class MusicWindow(App):

    def build(self):


        return MyFloatLayout()





if __name__ == "__main__":
    window = MusicWindow()
    window.run()

from kivy.app import App

from kivy.core.audio import SoundLoader

from kivy.uix.floatlayout import FloatLayout

class MyFloatLayout(FloatLayout):

def play_music(self):

music = SoundLoader.load('music.mp3')

if music:

music.play()

class MusicWindow(App):

def build(self):

return MyFloatLayout()

if __name__ == "__main__":

window = MusicWindow()

window.run()

Now you need to create a .kv file, iam going to call it musicwindow.kv, make sure that your kv file name should be the same as your main App class, in my case my main window class name is MusicWindow, and my kv file name should be musicwindow.kv. in the kv file we have just created a button, and we have connected the button with the play_music() method that is located in our MyFloatLayout class.

#:kivy 1.10.0


<MyFloatLayout>:

    Button:
        bold:True
        size_hint:.8,.3
        text:'Play Music'
        background_color:0,1,1,1
        pos_hint: {'right':1, 'y':0}
        on_release: root.play_music()

#:kivy 1.10.0

<MyFloatLayout>:

Button:

bold:True

size_hint:.8,.3

text:'Play Music'

background_color:0,1,1,1

pos_hint: {'right':1, 'y':0}

on_release: root.play_music()

So run the complete code this will be the result, if you click on the button, the mp3 music

will be played.

Good, the first thing is to thank you for your
videos has helped me learn. I would like to ask you a question about printing with QPrintPreviewDialog. As I could avoid the 20mm margins in the prints, I would like less than a 5mm. Thanks a greeting
