pygame.org

I have an example that can help get you started with the core basics, window, key input, audio, etc.

import pygame
from pygame import mixer
import sys

def Example():
#initialize pygame
    pygame.init()
#initialize sound mixer
    mixer.init()
#create display
    window = pygame.display.set_mode([640,480])
#load sound
    sound = mixer.Sound('tone5.wav')

#main update loop
    while True:
        for event in pygame.event.get():
            if event.type == pygame.KEYDOWN:
            #if space is pressed, play sound
                if event.key == pygame.K_SPACE:
                    sound.play()
            #if escape is pressed, quit
                if event.key == pygame.K_ESCAPE:
                    pygame.quit()
                    sys.exit(0)

    #update window
        pygame.display.update()

Example()

If you want an example using my own OpenAL wrapper instead of pygames limited mixer, feel free to ask.

that was the function definition.
The function wasn't called in the main program, that's why the code doesn't execute

either type example() at the end of the file, or use something like:
if __name__ == '__main__':
example()

I have some problems.
I create a function, I put the commands of sounds and keys, but any key that I press the program closes.
What can I do?

A good thing that I learned is typing this into your command line or power shell.
python script.py>output.txt
This will capture any text your program outputs into a file called output.txt  which will be located in the directory of your script.  This is good because some tracebacks are silent, and you need to know how to review the screen to see them. That command eliminates the need.

python script.py > output.txt 2>&1 is even better and pipes errorneous output as well when under Windows . When under Linux, python script.py >& output.txt works fine as well.
