IT244-2 Temperature Converter

Purpose

In this assignment, you will create a user-defined function passing variables both by value and by reference and using arguments of different data types.

Assignment Requirements

For this project, you will write a program that requests a temperature value and the temperature scale used from the user. Write a single function that evaluates a given temperature and returns associated conversions. For example, the user could input a temperature value in Fahrenheit and receive the temperature in its Celsius equivalent.

For example, the user could input a temperature value in Fahrenheit and receive the temperature in its Celsius equivalent.

Conversion formulas for your reference:

F = (C * 9/5) + 32
C = (F - 32) * 5/9

Assignment Instructions

1. Use the def keyword to define a temperature conversion function (i.e., convertTemp) that accepts two parameters (a temperatures list and a temperature scale letter value [i.e., temps, tempScale]).

• When the temperature scale entered is F, incorporate a formula to calculate the Celsius equivalent and place the result in the appropriate index position in the temps list. See conversion formula above in requirements.
• When the temperature scale entered is C, incorporate a formula to calculate the Fahrenheit equivalent and place the result in the appropriate index position in the temps list. See conversion formula above in requirements.
• Return temps list.

Example prompts:

Enter a temperature value:
Enter a single letter to indicate the temperature scale (C or F):

Hint: Placing float ahead of the input statement will store the user input as a decimal number data type. Since the temperature value will be used in the conversion calculation, you will want this to be a numeric value. You may incorporate additional optional data validation as you wish.

4. Define and initialize your temps list to hold two number values

Hint: Initialize both positions to zero for now. The user will only be entering one temperature value, so you will have to fill in one position in the list with that value and leave the other as zero to be converted when the function is called.

temps[0] = tempEntered

6. Call your temperature conversion function passing it the temperature values in a list and a letter code for temperature scale.

EXPECTED OUTPUT:

Enter a temperature value: 32
Enter a single letter to indicate the temperature scale (C or F): F
You entered 32.0 degrees F >>>
The temperature in Celsius is 0.0
The temperature in Fahrenheit is 32.0
