Run python script on arduino
Question: i have a python script to slice wav file using start, end time. I want to
execute this in arduino. can i run this directly into arduino? or if not, can
you suggest idea how can i do this?

    
    
    import wave
    import pygame
    import time
    import sys
    
    
    def slice(infile, outfilename, start_ms, end_ms):
        width = infile.getsampwidth() #Returns sample width in bytes
        rate = infile.getframerate()  #Returns sampling frequency
        fpms = rate / 1000 # frames per ms
        length = (end_ms - start_ms) * fpms
        start_index = start_ms * fpms
    
        out = wave.open(outfilename, "w")
        out.setparams((infile.getnchannels(), width, rate, length, infile.getcomptype(), infile.getcompname()))
    
        infile.rewind()             #Rewind the file pointer to the beginning of the audio stream
        anchor = infile.tell()      #Return current file pointer position
        infile.setpos(anchor + start_index)  #Set the file pointer to the specified position
        out.writeframes(infile.readframes(length)) #Write audio frames and make sure nframes is correct
    
    
    if __name__ == "__main__":
    
           slice(wave.open("song1.wav", "r"), "out.wav", int(sys.argv[1]), int(sys.argv[2]))
    
           pygame.mixer.init()
           pygame.mixer.music.load("out.wav")
           pygame.mixer.music.play()
           while pygame.mixer.music.get_busy() == True:
                 continue
    


Answer: If you are using an arduino mega you could take a look at
[PyMite](http://playground.arduino.cc/CommonTopics/PyMite).

For arduino uno there was a post ([Is there a way to "compile" Python code
onto an Arduino (Uno)?](http://stackoverflow.com/questions/8114916/is-there-a-
way-to-compile-python-code-onto-an-arduino-uno)), about compiling python for
arduino and in it there were mentioned two projects
[pyMCU](http://www.pymcu.com/overview.html) and the other one in developement
by a SOer, you could give it a try

But as they said, porting it to C++ is the easier way
