Explanation of Solution

Denotational Semantics:

The Denotational Semantics are used to define the meaning of programs. It is based on recursive function theory. A recursion is a concept in which a function is called itself.

Example of factorial of a number:

if (n==0) then 1 else n*factorial(n-1)

In denotational semantics a mathematical object is constructed. This object is known as denotation. The denotation of a phrase is determined by the denotations of its sub phrases. Denotational semantics provided the meaning of a computer program as a function which mapped input into output...

Scenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you…
