Question

Python

1. A salesman can sell five different items. Write a program that lets the salesman enter the quantity of each item sold, calculates the total sales, and prints as below. Use a for loop to ask the salesman how many of each product he sold.

tem 1 $2.50

Item 2 $1.98

Item 3 $5.75

Item 4 $3.45

Item 5 $4.00

2. Rewrite program #1 using a for loop to run for 3 salesmen and print the total sales for each

salesman as below.

3. Rewrite program #2 to let the salesman determine when he/she is finished entering the

item/quantity.

Answer 1

1.

CODE

prices = []

quantity = []

for i in range(1, 6):

quantity.append(int(input("Quantity sold for item %d? " %i)))

prices.append(float(input("Price of item %d? " %i)))

for i in range(5):

totalCost = prices[i] * quantity[i]

print("Item %d $%.2f" %(i+1, totalCost))

2.

CODE

for j in range(1, 4):

print("Enter details of Salesperson %d" %(j))

prices = []

quantity = []

for i in range(1, 6):

quantity.append(int(input("Quantity sold for item %d? " %i)))

prices.append(float(input("Price of item %d? " %i)))

for i in range(5):

totalCost = prices[i] * quantity[i]

print("Item %d $%.2f" %(i+1, totalCost))

3.

CODE

for j in range(1, 4):

print("Enter details of Salesperson %d" %(j))

prices = []

quantity = []

i = 1

while(True):

quantity.append(int(input("Quantity sold for item %d? " %i)))

prices.append(float(input("Price of item %d? " %i)))

i += 1

cont = input("Do you wish to continue? (yes/no) : ")

if cont.lower() == "no":

break;

for i in range(len(quantity)):

totalCost = prices[i] * quantity[i]

print("Item %d $%.2f" %(i+1, totalCost))
