I've been taking the Computer Science course on Codecademy. The course includes this project where we have to create a python script to find the cheapest shipping method based on the weight of an item and I'm just wondering if what I wrote is the best solution or if there's a better one.
def ground_shipping_cost(weight):
flat_cost = 20
premium_cost = 125
if weight <= 2:
flat_cost += weight * 1.50
elif weight > 2 and weight <= 6:
flat_cost += weight * 3.00
elif weight > 6 and weight <= 10:
flat_cost += weight * 4.00
elif weight > 10:
flat_cost += weight * 4.75
return flat_cost, premium_cost
def drone_shipping_cost(weight):
cost = 0
if weight <= 2:
cost = weight * 4.50
elif weight > 2 and weight <= 6:
cost = weight * 9.00
elif weight > 6 and weight <= 10:
cost = weight * 12.00
elif weight > 10:
cost = weight * 14.25
return cost
def cheapest_shipping(weight):
ground_cost, premium_cost = ground_shipping_cost(weight)
drone_cost = drone_shipping_cost(weight)
if drone_cost < ground_cost and drone_cost < premium_cost:
return "You should use drone shipping as it will only cost " + str(drone_cost)
if ground_cost < drone_cost and ground_cost < premium_cost:
return "You should use standard ground shipping as it will only cost " + str(ground_cost)
if premium_cost < ground_cost and premium_cost < drone_cost:
return "You should use premium shipping as it will only cost " + str(premium_cost)
print(cheapest_shipping(4.8)) # You should use standard ground shipping as it will only cost 34.4
print(cheapest_shipping(41.5)) # You should use premium shipping as it will only cost 125
print(cheapest_shipping(1.5)) # You should use drone shipping as it will only cost 6.75
print(cheapest_shipping(4.0)) # You should use standard ground shipping as it will only cost 32.0
The issue I see is maybe there's too many if, elif statements and I was wondering if there's a way to simplify the program.
