Definitely you'll want to learn python before you go much farther in
this project. Check out the online docs, tutorials, etc.

Here's some almost runnable code that might help you get down the right
track. You'll have to fill in some of the stuff.
temperatures.py:
import time
sensorids = [...] #fill in these with your ids
def _read_sensor(id):
# open /sys/bus/w1/deevices/id/slave
text = ''
while text.split("\n")[0].find("YES") == -1:
tfile = open("/sys/bus/w1/devices/"+ id +"/w1_slave")
text = tfile.read()
tfile.close()
time.sleep(0.1)
temperaturedata = text.split("\n")[1].split(" ")[9]it(" ")[9]
temperature = float(temperaturedata [2:]) / 1000
return temperature
def get_temperatures():
# not using list comprehensions but we could
temps = []
for sensor in sensorids:
temps.append(_read_sensor(sensor))
Then in your other python modules (scripts):
import temperatures
print temperatures.get_temperatures() # should print a list
Hope this gives you a bit of structure you can use. All the code you
need to fill in can come from the code you posted previously.
