Looking at the code for this:

try:
    # Local variables.
    low  = 200          # Low value for light level (lux).
    high = 2000         # High value for light level (lux).
    period = 90        # Delay, in seconds, between calls.
    lights_on = False  # Set the state of the lights to off.

How do I set a range?
I.e., low <= 200, high >= 2000?

Thank you.
