[split] Check presence of a file

[gontajones]

The first file:

def read_sensor(sensorID)
   tempfile = open("/sys/bus/w1/devices/"+ sensorID +"/w1_slave")
   thetext = tempfile.read()
   tempfile.close()
   tempdata = thetext.split("\n")[1].split(" ")[9]
   temperature = float(tempdata[2:])
   temp_sensor = temperature / 1000
   print (temp_sensor)

Seconde file:

# Execute DS18B20 function for sensor ID's below.
# As sensorsID is a dictionary, you declare it like this:
sensorsID = {
    'solar_panel': float(read_ds18b20('28-0516a3ff90ff')),   
    'top_cyl': float(read_ds18b20('28-0317003f1cff')),
    'flow_panel': float(read_ds18b20('28-0416c4a3a0ff'))
}

Now, in the last file:

from mySensorModule import read_sensor
from mySensors import sensorsID
# Accessing a dictionary: dict_name[key] = value
sID = sensorsID['solar_panel']
read_sensor(sID)
# Or...
read_sensor(sensorsID['solar_panel'])

PS: Raspi is so cool!
