Calculate a total

Expressions calculate values.

* multiplies numbers. Multiplication has priority over addition; parentheses make grouping explicit. A dictionary holds named values such as input["price"]. These examples use whole currency units.

A shopping receipt multiplies each item price by its quantity before calculating a total.

Read the example

price = 4
quantity = 3
print(price * quantity)

12

Your challenge

Return input["price"] multiplied by input["quantity"]. Input is an object with both numbers.

Common trap

Use dictionary key access, not input.price.
