Question

The question in the textbook is as follows:

Hot Dog Cookout Calculator

Assume that hot dogs come in packages of 10, and hot dog buns come in packages of 8. Design a modular program that calculates the number of packages of hot dogs and the number of packages of hot dog buns needed for a cookout, with the minimum amount of leftovers. The program should ask the user for the number of people attending the cookout, and the number of hot dogs each person will be given. The program should display the following:

• The minimum number of packages of hot dogs required

• The minimum number of packages of buns required

• The number of hot dogs that will be left over

• The number of buns that will be left over

This is the python code I have for the unmodularized version. I figured if I could figure out the unmodularized version I could convert it to modularized, but unfortunately I am stuck.on how to proceed further.

This is the python code I have so far.

num_of_pkg_of_dogs = 0

num_of_pkg_of_buns = 0

dogs_per_pkg = 10

buns_per_pkg = 8

leftover_dogs = 0

leftover_buns = 0

total_num_dogs = 0

total_num_buns = 0

num_attending_cookout = 0

num_of_dogs_pp = 0

pkg_of_dogs_needed = 0

pkg_of_buns_needed = 0

num_attending_cookout = int(input("Enter number of people attending cookout: "))

num_of_dogs_pp = int(input("Enter number of Hot Dogs per person: "))

total_num_dogs = num_attending_cookout*num_of_dogs_pp

total_num_buns = num_attending_cookout*num_of_dogs_pp

print("Total number of hot dogs needed: ", total_num_dogs)

print("Total number of buns needed: ", total_num_buns)

pkg_of_dogs_needed = total_num_dogs/dogs_per_pkg

pkg_of_buns_needed = total_num_buns/buns_per_pkg

print("Packages of hot dogs needed: ", pkg_of_dogs_needed)

print("Packages of buns needed: ", pkg_of_buns_needed)

Answer 1

I have divided the code into 4 modules, namely
main.py
info.py
calculation.py
requirements.py

_______________________________________________

info.py
CODE:

#this module takes the input information from the user
total_num_dogs = 0
total_num_buns = 0#initializing the variables
num_attending_cookout = 0
num_of_dogs_pp = 0

num_attending_cookout = int(input("Enter number of people attending cookout: ")) #asking the user the number of people for cookout
num_of_dogs_pp = int(input("Enter number of Hot Dogs per person: ")) #asking the user for the number of hot dogs per person ot be made
total_num_dogs = num_attending_cookout*num_of_dogs_pp #calculating the number of dogs needed
total_num_buns = num_attending_cookout*num_of_dogs_pp #calculating the number of buns needed

_______________________________________________
requirement.py
CODE:

#this module is used to calculate the amount of packages needed
import  info #calling the info module for the gathered info ot be available in this module
import math #math funciton

pkg_of_dogs_needed = 0
pkg_of_buns_needed = 0#initializing the variables
dogs_per_pkg = 10
buns_per_pkg = 8

pkg_of_dogs_needed = math.ceil(info.total_num_dogs/dogs_per_pkg) #calculating the number of package of dogs needed and using the ceil funciton to get a valid integer number of package
pkg_of_buns_needed = math.ceil(info.total_num_buns/buns_per_pkg) #calculating the number of package of buns needed and using the ceil funciton to get a valid integer number of package

___________________________________________

calculation.py
CODE:

#this module will calculate the amount of leftovers
import requirement
import info

leftover_dogs = 0
leftover_buns = 0

leftover_dogs = requirement.pkg_of_dogs_needed*requirement.dogs_per_pkg - info.total_num_dogs #leftover dogs is the difference between the required number of dogs to the available number of dogs in the package
leftover_buns = requirement.pkg_of_buns_needed*requirement.buns_per_pkg - info.total_num_buns #leftover buns is the difference between the required number of buns to the available number of buns in the package

___________________________________________________________

main.py
CODE:

#This is the main module where all the informations will be displayed and other modules will be called
import info #calling all the modules
import requirement
import calculation

print("Total number of hot dogs needed: ", info.total_num_dogs) #printing all the values gathered from various modules
print("Total number of buns needed: ", info.total_num_buns)
print("Packages of hot dogs needed: ", requirement.pkg_of_dogs_needed)
print("Packages of buns needed: ", requirement.pkg_of_buns_needed)
print("Number of dogs left: ",calculation.leftover_dogs)
print("Number of buns left: ",calculation.leftover_buns)
