ZyBooks My library ITCS 1 140 home> 10.9: Lab #12, part 1 E 7yBooks catalog Help/FAQ Emanuel Sam Problem Description A good friend of yours wants to start a diner join near campus. He wants to keep the menu simple and plans to offer burgers, fries, wraps and salads. Additionally he wants to offer quick service. Therefore, he is looking for a mobile application whereby students can put there order in ahead of time and pick it up. He has assembled a team of fellow students to help write the app. Your job is to write the portion of the app that deals with hamburger sales. Your portion of the app needs to do the following: @Ask the user for the type of burger they want either single or double patty. A single patty burger costs $5.95 and a double costs $7.95 @Ask the user for the extras for their burger. A typical burger comes with tomato, onion and pickles. Cheese, bacon, grilled onions and grilled mushrooms are extra. These extra costs are as follows: Cheese $0.75, Bacon $1.00, Grilled Onions- $0.50, Grilled Mushrooms $0.50 or none = $0.0. @Display to the user the cost of the patty,extras cost and total cost Creating the Class Use the template to get started. Your class should have attributes, a constructor, methods and access methods to allow values to leave the class. Assume all attributes are private and cannot be accessed from the program. Your class will need the patty type sent into it. The methods will determine the patty cost, extras cost and the total cost. The access methods will return these three values back to main0 Below is an example of the extras menuExplanation / Answer
class BurgerCost:
#constructor
def __init__(self, newburgertype):
#attributes
self.burgertype = newburgertype
self.single = 5.95
self.double = 7.95
self.burgerbasecost = float()

self.cheese = 0.75
self.bacon = 1.0
self.grilledonions = 0.50
self.grilledmushrooms = 0.50
self.total = float()
self.extra = None
def setExtras(self, extra):
self.extra = extra
def determineBaseCost(self):

elif self.extra == 'B':
self.extracost = self.bacon
elif self.extra == 'O':
self.extracost = self.grilledonions
else:
self.extracost = self.grilledmushrooms
def returnBaseCost(self):
return self.burgerbasecost
def returnExtraCost(self):
return self.extracost
def returnTotalCost(self):
return self.burgerbasecost + self.extracost
if __name__ == '__main__':
burgertype = raw_input('Please enter the type of burger you want: S - Single D - Double ')
burger_cost = BurgerCost(str.upper(burgertype))
extra = raw_input('Enter your extras: C - Cheese B - Bacon O - Grilled Onions M - Grilled Mushrooms N - None ')
burger_cost.setExtras(extra)
burger_cost.determineBaseCost()
burger_cost.determineExtraCost()
print 'Your bill:'
print 'Patty cost: ${}'.format(burger_cost.returnBaseCost())
print 'Extra cost: ${}'.format(burger_cost.returnExtraCost())
print 'Total cost: ${}'.format(burger_cost.returnTotalCost())
# Sample Output
Please enter the type of burger you want:
S - Single
D - Double
s
Enter your extras:
C - Cheese
B - Bacon
O - Grilled Onions
M - Grilled Mushrooms
N - None
