Think of ways to improve the Math Wizard program, and try to implement them.
For example, add some colors to make the output look fancier or draw something
after each puzzle.

1. Let’s write a spelling quiz game using homonyms. Homonyms are
words that sound the same but have different meanings. Use Notepad
to create the following text file:
In your math class;ad/add;add
Halloween queen;which/witch;witch
Eyes do this;sea/see;see
In the church;altar/alter;altar
A rabbit;hair/hare;hare
A good story;tail/tale;tale
Animals have them;clause/claws;claws
Pencils do this;right/write;write
Each line in this file contains three fields separated by semicolons.
The first field is the hint you’ll show the player, such as In your math
class. The second field is the two possible answers that your player will
choose from, such as ad/add. The third field is the correct answer, such
as add.
In each round, have the program display the hint and the two possible
answers to the player, and then wait for them to enter their answer.
Have the program compare the user’s answer with the correct answer,
and then let them know whether their answer is correct.
