The following Python program calculates the total volume of water required daily for a livestock enclosure, including a fixed daily loss due to evaporation:
herd_size = int(input("Enter the number of animals: "))
evaporation_loss = 45.5
total_water_needed = (herd_size * 12.5) + evaporation_loss
print("Total daily water required (litres):", total_water_needed)
Identify one variable in this program that would be more appropriate to define as a constant.
