Question

implement the following logic in Python, use appropriate data types. Data types are represented as either numeric (num) or string.

string name

string address

num item

num quantity

num price

num SIZE = 6

num VALID_ITEM [SIZE] = 106, 108, 307, 405, 457, 688

num VALID_ITEM_PRICE [SIZE] = 0.59, 0.99, 4.50, 15.99, 17.50, 39.00

num sub

string foundIt = “N”

string MSG_YES = “Item available”

string MSG_NO = “Item not found”

get name, address, item, quantity

sub = 0

while sub <= SIZE

if item == VALID_ITEM [sub] then

foundIt = “Y”

price = VALID_ITEM_PRICE [sub]

endif

sub = sub + 1

endwhile

if foundIt == “Y” then

print MSG_YES

print quantity, “ at “ , price, “ each”

print “Total “, quantity * price

else

print MSG_NO

endif

Answer 1

#declare valid item list
VALID_ITEM = [106,108,307,405,457,688]

#declare price for item
VALID_ITEM_PRICE = [0.59,0.99,4.50,15.99,17.50,39.00]

#inititalize sub to 0
sub = 0

#inititalize size to 6
SIZE = 6
foundit = 'N'

#takes name from user and store it in name variable
name = input("Enter name: ")

#takes address from user and store it in address variable
address = input("Enter address: ")

#takes item from user and store it in item variable
item = input("Enter item: ")

#takes quantity from user and store it in quantity variable
quantity = input("Enter quantity: ")

#checks if entered item is found in valid item list
#if found then change the value of foundit to Y 
# and store the price value for that item in price variable
while (sub < SIZE):
    if(int(item) ==  VALID_ITEM[sub]):
        foundit = 'Y'
        price = VALID_ITEM_PRICE[sub]
    sub = sub+1

#if foundit is Y then Item is availabe
#prints quantity and price for that Item and total price     
if(foundit == 'Y'):
    print("Item available")
    print(quantity ," at ", price, " each ")
    print("Total: ", int(quantity) *float(price))

#if foundit is N then item not found in VALID_ITEM list
#prints item not found
else:
    print("Item not found")

OUTPUT:
