Question

I asked for help before and still the script is not working properly. 1- I do not get the question if I want to quit or continue even though I have a conditional statement, the loop is never-ending, my while loop is not working, the quantity variable has an error that is not defined, my for loop since wrong my if is not working, summary = I can't run this, can somebody please give me some light as to what am I doing wrong ( this is the second time asking, please help!).

The task is broken down into three sections.

Section 1 - User Input

Section 2 - loop through the grocery list

Section 3 - provide output to the console

#Task: Create the empty data structure

grocery_history = []

grocery_item = {}

#Variable used to check if the while loop condition is met

stop = 'False'

while stop == 'False':

#Accept input of the name of the grocery item purchased.

item_name = str(input("Item name:n"))

#Accept input of the quantity of the grocery item purchased.

quantity = int(input("Quantity purchased:n"))

#Accept input of the cost of the grocery item input (this is a per-item cost).

cost = float(input("Price per item:n"))

#Using the update function to update the dictionary entry which contains the name, number and price entered by the user.

grocery_item = {'item_name': name, 'quantity': int(quantity), 'cost': float(cost)}

#Add the grocery_item to the grocery_history list using the append function

grocery_history.append(grocery_item.copy())

#Accept input from the user asking if they have finished entering grocery items.

asking = input("Would you like to enter another item? nType 'c' for continue or 'q' to quit:n");

if asking == 'q':

stop = 'True'

# Define variable to hold grand total called 'grand_total'

grand_total = 0

#Define a 'for' loop.

for element in grocery_history:

#Calculate the total cost for the grocery_item.

total_cost = element['quantity'] * element['cost']

#Add the item_total to the grand_total

grant_total += item_total

#Output the information for the grocery item to match this example:

#2 a..;@ $1.49 ea $2.98

print(str(element['number'])+' ' + element['name'] + ' @

+ str(element['price'])+ ' ea

+ str(item_total))

#Set the item_total equal to 0

item_total = 0

#Print the grand total

print("n GRAND TOTAL: $%.2f n" %(grand_total));
