open("myData.dat", "w").close()

while True:
     temp = sensor.readTempC()
     riga = "%f\n" % temp
     with open("myData.dat", "a") as f:
         f.write(riga)
     time.sleep(1)
yes great it works!thanks a lot!
Anyway to refresh temperature I've to recall anytime the php page.
My idea is to read for example the first line every x seconds...it should work.
Is it possible to use python and not php to plot data?
