Hi John,

You could use a dictionary to store the functions.  For example:

import module_a
import module_b

rain_functions = { 1:module_a.get_rain, 2:module_b.get_rain }

Then you could call the function as:

x = forecast()
points = x.getPoints()
for point in points:
    rain_functions[point]()

Hope this helps,
