Create a function avg_rainfall(day_list) that takes a list with the amount of rain for each day. There are some problems with the equipment, so ignore days that have a negative number for the amount of rain. Calculate the average rainfall as the sum of the non-negative values divided by the number of non-negative values. If at least one day has a non-negative rainfall return Average: (average) and otherwise return No rain. For example, avg_rainfall([30,-2, 0]) should return Average: 15 and avg_rainfall([-3, -2]) should return No rain.
