Python Codio Grocery List

First Part:

Task: Create the empty data structure

Create an empty dictionary with the variable name grocery_item

Create an empty list with the variable name grocery_history

Second Part:

Control Structure

The variable stop will be used with a while loop to check if the loop condition is true (and the loop will continue) or if the loop condition is false (and the loop will exit).

In this script, the loop will end when the user enters q

As the code in the while loop should run at least once, set the stop variable to anything other that 'q, e.g. 'go' or True

stop = 'go'

Write a loop that will be used to collect user input.

The While loop will use the stop variable to determine if the user has completed entering their grocery items.

The following steps will all be completed if the loop condition is met (i.e., the user has not entered 'q'):

Accept input of the name of the grocery item purchased.

Prompt: "Item name: " Variable: item_name

Accept input of the quantity of the grocery item purchased.

Prompt: "Quantity purchased: " Variable: quantity

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

Prompt: "Price per item: " Variable: cost

Create a dictionary entry which contains the name, number and price entered by the user. Assign the entry to a variable named grocery_item

The format will be:

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

Add the grocery_item to the grocery_history list using the append function

Prompt the user for input asking if they have finished entering grocery items. Use the prompt:

"Would you like to enter another item? Type 'c' for continue or 'q' to quit: "

Third Part:

Looping Through the List

In this section, you will loop through the grocery_history list. For each item, you will:

Your results will look similar to this:

2 apple @ $1.49 ea $2.98 1 milk @ $3.99 ea $3.99 Grand total: $6.97 

Print the number of that item purchased

Print the name of the item

Print the price paid for all of those items purchased

Add this price to the grand total for the entire list

Forth Part:

Print the List

Inside the for loop:

Define variable to hold grand total called grand_total

Define a 'for' loop. This loop will examine each element in the grocery_history list.

The loop will use the 'for in' convention. Each grocery_history list element will be assigned to a variable named 'grocery_item'

Output 2 apple @ $1.49 ea $2.98
Variable number name price item_total

Reminder

Your can use the %.2f formatting expression to format the dollar amounts

Calculate the total cost for the grocery_item. The calculation is:

item_total = number * price

Add the item_total to the grand_total

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

Set the item_total equal to 0

Finally, after printing all the items, print the grand total!
