Question

You are off to shopping and need a program that allows you to enter the names of items, their price and quantities. Here is what a sample run should look like (with the keyboard input shown in italics) ...

    Enter item information ("exit" to exit)
    item 1: chips
    price: 3.5
    quantity: 2
    Enter item information ("exit" to exit)
    item 2: red wine
    price : 15.0
    quantity : 1
    Enter item information ("exit" to exit)
    item 3 : steaks
    price : 15.0
    quantity : 2
        
    Your list:
    steaks               2    $30
    red wine             1    $15
    chips                2    $7
    -----------------------------
    Total                     $52

You must use PYTHON.

Code

import operator
i=1
l=[]
while(True):
        print('Enter item information ("exit" to exit)')
        m=[]
        print("item",str(i)+':',end=' ')
        item=input()
        if(item=='exit'):
                break
        print('price :',end='')
        price=float(input())
        print('quantity: ',end='')
        quantity=int(input())
        m.append(item)
        m.append(quantity)
        tot_price=int(quantity*price)
        m.append(tot_price)
        l.append(m)
        i=i+1
n=sorted(l, key=operator.itemgetter(2))
print()
print('Your list:')
total=0
for i in n:
        print(i[0],'      ',i[1],'   $'+str(i[2]))
        total+=i[2]
for i in range(29):
        print('_',end='')
print()
print('Total \t','        $'+str(total))
