when i test just the method “shipping_cost_ground” it works great. the math is correct. but when i run it at the end, the math is now wrong (according to the project). the final method, when called, gives me $13.80, which is wrong. please help! thanks so much!
here’s my code:
def shipping_cost_ground(weight): if weight <= 2.0: return (weight * 1.5) + 20.0 elif weight <= 6.0: return (weight + 3.0) + 20.0 elif weight <= 10.0: return (weight * 4.0) + 20.0 else: return (weight * 4.7) + 20.0 print(shipping_cost_ground(10)) shipping_cost_premium = 125.0 def shipping_cost_drone(weight): if weight <= 2.0: return weight * 4.5 elif weight <= 6.0: return weight + 9.0 elif weight <= 10.0: return weight * 12.0 else: return weight * 14.25 print(shipping_cost_drone(1.5)) def method_cost(weight): ground = shipping_cost_ground(weight) premium = shipping_cost_premium drone = shipping_cost_drone(weight) if ground < premium and ground < drone: method = "Ground" cost = ground elif premium < ground and premium < drone: method = "Premium" cost = premium else: method = "Drone" cost = drone print("The best way to ship this package is %s. The cost will be $%s." % (method, cost)) method_cost(4.8)
