JList.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION)

JList provides for simultaneous selection of multiple items upon setting the selection mode to MULTIPLE_INTERVAL_SELECTION. The API call for this purpose is:

jlist.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION)

Item = "quesadilla"

jok3333 [9.3K]

Answer:

item = "quesadilla"

meat = "steak"

queso = False

guacamole = False

double_meat = False

base_price = 4.5

if item == "quesadilla":

base_price = 4.0

elif item == "burrito":

base_price = 5.0

if meat == "steak" or meat == "pork":

base_price += 0.50

if meat == "steak" and double_meat:

base_price += 1.50

elif meat == "pork" and double_meat:

base_price += 1.50

elif double_meat:

base_price += 1.0

if guacamole:

base_price += 1.0

if queso and item != "nachos":

base_price += 1.0

print(base_price)

Explanation:

Use a conditional statement to check if meat is steak or pork then add 0.50 to base_price .
Check if the meat is steak or pork, then double_meat adds 1.50 or 1.0 otherwise .
Check if meat is steak and its double_meat , then add 1.50 and if its for guacamole, then add 1.00 to base_price . If queso is there and item is not nachos, add 1.00 to base_price .
Finally when item is nachos, no need to add any money to base_price .
