Hey there @css7985072411 and welcome to the Codecademy forums!!
There are a couple things to look at here. First check your indentation on the print() in cheapestPrice(). Second take a look at what you are trying to print() out:
print(
"The cheapest shipping method is " + method + " and it will cost you $ " + cost + "."
)
If cost is an integer how are you going to combine that with a string?
Thank you both for your help, when I fixed the integer and the else and print being connected I ended up with “The cheapest shipping method is normal ground shipping and it will cost you 39.2.
None
The cheapest shipping method is premium ground shipping and it will cost you 125.0.
None” when I printed it to the console, why is there 2 “None” after both sentences?
The code now looks like this at the last part
def cheapest_price(weight):
ground = normal_ground_ship(weight)
premium = premium_ground_ship
drone = drone_ship(weight)
if ground < premium and ground < drone:
cost = ground
method = "normal ground shipping"
elif premium < ground and premium < drone:
cost = premium_ground_ship
method = "premium ground shipping"
else:
cost = drone_ship
method = "drone shipping"
print(
"The cheapest shipping method is " + method + " and it will cost you $ " + str(cost) + "."
)
print(cheapest_price(4.8))
print(cheapest_price(41.5))
Okay thanks, the code is now working and ill taked a look at that guide. For future refrences is the “Classes” tag the place to ask these kind of questions?
I think being in the Python category is probably already good enough. For this post, I would have added general. Classes is in reference to another element of object oriented programming languages used to store different data type.
You will learn about these later on in the Python coursework, however some examples of classes you have already seen are the built in string, int, and float.
Good afternoon sir. Happy new year!!! please my code works and is correct in the context of this exercise. the problem is that i was trying to add user input as in Input(“please input weight”) such that the user can input the weight of their cargo into the system but i keep getting different errors every way i try especially an EOFError. please can you advise me on how to do this? thank you sir.
def ground_shipping(weight):
if (weight <= 2):
cost = (20 + (1.5 * weight))
elif (2 < weight <= 6):
cost = (20 + (3 * weight))
elif (6 < weight <= 10):
cost = (20 + (4 * weight))
else:
cost = (20 + (4.75 * weight))
return cost
premium_ground_shipping = 125
def drone_shipping(weight):
if (weight <= 2):
cost = (4.5 * weight)
elif (2 < weight <= 6):
cost = (9 * weight)
elif (6 < weight <= 10):
cost = (12 * weight)
else:
cost = (14.25 * weight)
return cost
def cheapest_package(weight):
if ground_shipping(weight) < (drone_shipping(weight) and premium_ground_shipping):
return "You should ship using ground shipping, it would cost " + str(ground_shipping(weight))
elif drone_shipping(weight) < (ground_shipping(weight) and premium_ground_shipping):
return "You should ship using drone shipping, it would cost " + str(drone_shipping(weight))
else:
return "You should ship using premium ground shipping, it would cost " + str(premium_ground_shipping)
print (cheapest_package(4.8))
An EOFError being thrown while using input() in the Codecademy IDE is most likely due to that particular lesson not having a console capable of receiving user input. There are not many lessons I remember that are able to use the input() function. You could of course copy your work over to your device or an online IDE and add user input to it there.
