Chapter 2, Problem 24RQ
Explanation of Solution
Comparison on discrete and analog I/O modules:
| Discrete I/O modules | Analog I/O modules |
| In discrete I/O modules, the output value may be either ON or OFF. | In analog modules, the output value may be any continuous value such as 0 to 440mA or 0 to 20 V within its specific range. |
| It allows connecting only ON/OFF devices... |

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…
