Problem: There are ten hot dogs in a package of hot dogs and eight buns in a package of buns. Return the number of packages of hot dog buns needed for the given number of packages of hot dogs (assuming one hot dog per bun). Note: you should import math in order to use a function from that module.

Question

My code:

def bun_packages_required(hotdog_packages_given):
	"""(int) -> int
	Return the number of bun packages required based off the number of hotdog packages given.
	(Assuming there is one hot dog per bun)
		
	bun_packages_required(4)
	5.0
		
	bun_packages_required(8)
	10.0
		
	bun_packages_required(12)
	15.0
		
	"""	
	hotdogs_in_package = 10 *hotdog_packages_given
	buns_in_package = 8
	return (hotdogs_in_package/buns_in_package)

Teachers Comments:   The following test cases failed:                                            |

this is my last problem if anybody could help me figure out what needs to be changed in my code in order to work

anonymous · Answer

So let me get this straight... if you have 2 packs of hot dogs = 20 hot dogs, you will need 20 buns which you can get from 3 packs of buns... which contains 24 buns.... should the answer then be 3 (packs of buns)?

anonymous · Answer

i guess and thered be a left over amount of buns that go unused too right? which is what i assume hes referring to. in my equation when i plug in 2 for the pack of hotdogs, ill recieve 2.50 i think

anonymous · Answer

which is technically right but its impossible to buy 2.5 packages im assuming

anonymous · Answer

should i then put something in the code to round my answer?

anonymous · Answer

then what you can do is get the number of bun packs --> number of hot dog packs * number of hot dogs per pack / number of buns per pack.

then use math.ceil to get the number rounded up to the nearest integer!

anonymous · Answer

alright! that sounds good cause that way i can import math as well

okay and what about the whole concept of no buns i dont get why he asking waht i think that will be, should i just write  a comment in the string i have at teh beginning of the code?

anonymous · Answer

no idea about the teachers comments. is that all the info?

anonymous · Answer

ye thats everything

anonymous · Answer

so what are these test cases? bun_packages_required_no_buns and test_bun_packages_required_leftover_many ?

anonymous · Answer

and test_bun_packages_required_leftover_few

anonymous · Answer

those werent alll the test cases, just the ones that my code failed, he didnt tell me the other tests

anonymous · Answer

you don't have access to these test cases? you don't know what values the teacher is using?

anonymous · Answer

no, not at all, all i know is what he sends me

anonymous · Answer

it doesn't really make sense! no idea mate... just go with the math.ceil or be clever and say that if there is only one hot dog left i boil it and have it with my beans! hahaha

anonymous · Answer

LMAO ill do that, thanks a lot for the help bro. he gonna premark it again, so ill let you know what comes up

anonymous · Answer

cool!
