Question about the underscore need to clarify

Question

How come i need an underscore if i were to write roll_again="yes"

Answer 1

python doesn't like spaces in variable names/class names/function names. You can either use underscores as replacements, or make the name all one word, separating words with capitals such as:
spillMilk or RollAgain

Answer 2

You can name your variable the way you like, as long as it is (somehow) consistent within your code. You can name if rollAgain, if you want. It is just a convention to write variables with an underscore between words in Python
