Alan Thank you so much for the reply, attached is a screenshot of a

this is what I need the alarm for.
I am using Python 2.7? and Windows 7.
1. Should I reply-all, or ok to you? or either?
ReplyAll please, that way you get responses from everyone not just me.
And that's a very good thing, trust me! :-)
3. The data is coming from a serial port from an arduino........and I
think this is a "string"
Yes, in Python2 it will be, in Python 3 it will be a bytestring
but you can ignore that for now! :-)

Thats exactly correct. int() converts the string to a number.

Tell us what you see and what you expect.
The good news, is I do see the data in python, either a string or int???
The good news, is I can play the sound file as it is below.
Great, we'll look at it in more detail.
import serial #Import Serial Library
import time # Slows the print
import winsound
arduinoSerialData = serial.Serial('com7', 9600) #Create Serial port
object called arduinoSerialData # Don't change this.
myData = (arduinoSerialData.readline())
What happens if you print myData here?
while (1==1):
use
while True:
instead of the equality test.
> myData = int (arduinoSerialData.readline())
> if myData >33500:
print(arduinoSerialData.readline())
Note this is printing the next thing from Arduino but not storing it
anywhere.
You are throwing it away...
time.sleep(1) #Slows to 1000ms
soundfile = "c:\Windows\Media\Alarms\Alarm.wav"#Song/Track
to play(MUST be wav)
Windows paths can be troublesome due to the \ characters
which Python treats as special, you should prefix them with r
to tell Python to ignore the \
soundfile = r"c:\Windows\Media\Alarms\Alarm.wav"
Alternatively use Unix style / instead:
soundfile = "c:/Windows/Media/Alarms/Alarm.wav"
