Question

(Financial: compare costs) Suppose you shop for rice and find it in two differentsized packages. You would like to write a program to compare the costs of the packages. The program prompts the user to enter the weight and price of each package and then displays the one with the better price. Here is a sample run:

Step 1

This can be done using the input function in Python. For example, we can use the following code to get the weight and price of the first package: \[ \text{{weight1 = float(input("Enter weight for package 1: "))}} \] \[ \text{{price1 = float(input("Enter price for Show more…

Key Concepts

User Input

User input is the process of receiving data from the user, which is essential for making programs interactive. In this context, it involves capturing numerical values such as the weight and price of each package from the user.

Arithmetic Operations

Arithmetic operations, particularly division, are used to compute the cost per unit weight by dividing the price of an item by its weight. This calculation is fundamental for comparing the relative expense of different packages.

Unit Cost Calculation

Unit cost calculation involves determining the price per standard unit of measure (e.g., per pound or kilogram). This metric allows for a direct comparison of cost efficiency between products of different sizes or packaging.

Conditional Logic

Conditional logic is employed in programming to execute different actions based on specific conditions. In this scenario, it is used to compare the unit costs of the packages and determine which one is more economical.
