Subject: Debug EOFError in Python program

Hi, If anyone can help me to remove the following error in Python program that runs in Codio.

Item name: Quantity purchased: Price per item: Would you like to enter another item? Type 'c' for continue or 'q' to quit: Item name: Traceback (most recent call last): File "grocery_list.py", line 21, in <module> item_name = input("Item name: ") EOFError: EOF when reading a line Expected: Item name: Quantity purchased: Price per item: Would you like to enter another item? Type 'c' for continue or 'q' to quit: 1 milk @ $2.99 ea $2.99 Grand total: $2.99 

Below is my code:

#Task: Create the empty data structure

grocery_item = {}

grocery_history = []

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

stop = False

while not stop:

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

item_name = input("Item name: ")

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

quantity = input("Quantity purchased: ")

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

cost = input("Price per item: ")

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

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

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

grocery_history.append(grocery_item)

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

response = input("Would you like to enter another item? Type 'c' for continue or 'q' to quit: ")

if response == 'q':

stop = True

# Define variable to hold grand total called 'grand_total'

grand_total = 0

#Define a 'for' loop.

for item in grocery_history:

#Calculate the total cost for the grocery_item.

item_total = item['number'] * item['price']

#Add the item_total to the grand_total

grand_total += item_total

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

#2 apple @ $1.49 ea $2.98

print("%d %s @ $%.2f ea $%.2f" %(item['quantity'], item['item_name'], item['cost'], item_total))

#Set the item_total equal to 0

item_total = 0

#Print the grand total

print("Grand total: $%.2f" % grand_total)
