Hello there,

yes in the game instructions in the readme file it says to pick a letter in step number 4 but in the game, it says to enter a number. I would like to change step 4 in readme from letters to numbers. Also, I would like to update the Quiz-game.py to make your instructions more consistency, for example, in the selecting category it says:

and in the question-answering section it says:

I would like to make them more consistent by it saying "Enter Your Choice " followed by the letters or numbers the user can enter for a valid input so it looks like:

Also in the quiz, the general instructions it says to choose a number but only the letters are being displayed on the left margin of answers. So I would like to change this in the general instructions and add "Quiz will start momentarily" so the user knows not to press anything else and the game will start soon automatically.

After:

If that works ill send in a PR.

Thank You
