💼 Career

Understanding invoice generation is useful for roles in accounting, sales, and business management.

1

Create the product list

Create a list called products with these exact entries as dictionaries: {'name': 'Pen', 'price': 1.5, 'quantity': 10}, {'name': 'Notebook', 'price': 3.0, 'quantity': 5}, and {'name': 'Eraser', 'price': 0.5, 'quantity': 20}.

No-Code

# Create the list of products with name, price, and quantity
# Your code here

Need a hint?

Use a list of dictionaries. Each dictionary should have keys: 'name', 'price', and 'quantity'.

2

Add the tax rate

Create a variable called tax_rate and set it to 0.07 to represent 7% sales tax.

No-Code

products = [
    {'name': 'Pen', 'price': 1.5, 'quantity': 10},
    {'name': 'Notebook', 'price': 3.0, 'quantity': 5},
    {'name': 'Eraser', 'price': 0.5, 'quantity': 20}
]
# Create the tax_rate variable
# Your code here

Need a hint?

Set tax_rate to 0.07 to represent 7% tax.

3

Calculate subtotal and total

Create a variable called subtotal and set it to 0. Use a for loop with variables item to go through products. For each item, add item['price'] * item['quantity'] to subtotal. Then create a variable called total and set it to subtotal plus subtotal * tax_rate.

No-Code

products = [
    {'name': 'Pen', 'price': 1.5, 'quantity': 10},
    {'name': 'Notebook', 'price': 3.0, 'quantity': 5},
    {'name': 'Eraser', 'price': 0.5, 'quantity': 20}
]
tax_rate = 0.07
# Calculate subtotal and total
# Your code here

Need a hint?

Start subtotal at 0. Use a for loop to add price times quantity for each product. Then calculate total by adding tax.

4

Complete the invoice

Create a dictionary called invoice with keys: 'items' set to products, 'subtotal' set to subtotal, 'tax_rate' set to tax_rate, and 'total' set to total.

No-Code

products = [
    {'name': 'Pen', 'price': 1.5, 'quantity': 10},
    {'name': 'Notebook', 'price': 3.0, 'quantity': 5},
    {'name': 'Eraser', 'price': 0.5, 'quantity': 20}
]
tax_rate = 0.07
subtotal = 0
for item in products:
    subtotal += item['price'] * item['quantity']
total = subtotal + (subtotal * tax_rate)
# Create the invoice dictionary
# Your code here

Put all parts together in one dictionary called invoice.
