Pygame is the go-to library for making multimedia applications, especially games, in Python. The official website is http://www.pygame.org/.

Pygame's mixer module
pygame.mixer module helps control the music used in
pygame programs. As of now, there are 15 different functions for the
Similar to how you have to initialize
pygame.init(), you must initialize
pygame.mixer as well.
By using the first option, we initialize the module using the default values. You can though, override these default options. By using the second option, we can initialize the module using the values we manually put in ourselves. Standard values:
To check whether we have initialized it or not, we can use
pygame.mixer.get_init(), which returns
True if it is and
False if it is not. To quit/undo the initializing, simply use
pygame.mixer.quit(). If you want to continue playing sounds with the module, you might have to reinitialize the module.
As your sound is playing, you can pause it tempoparily with
pygame.mixer.pause(). To resume playing your sounds, simply use
pygame.mixer.unpause(). You can also fadeout the end of the sound by using
pygame.mixer.fadeout(). It takes an argument, which is the number of milliseconds it takes to finish fading out the music.
You can play as many songs as needed as long there are enough open channels to support them. By default, there are 8 channels. To change the number of channels there are, use
pygame.mixer.set_num_channels(). The argument is a non-negative integer. If the number of channels are decreased, any sounds playing on the removed channels will immediately stop.
To find how many channels are currently being used, call
pygame.mixer.get_channels(count). The output is the number of channels that are not currently open. You can also reserve channels for sounds that must be played by using
pygame.mixer.set_reserved(count). The argument is also a non-negative integer. Any sounds playing on the newly reserved channels will not be stopped.
You can also find out which channel isn't being used by using
pygame.mixer.find_channel(force). Its argument is a bool: either True or False. If there are no channels that are idle and
force is False, it will return
force is true, it will return the channel that has been playing for the longest time.
