1. Comments: are any text to the right of the # symbol and is mainly useful as notes for the reader of the program. Use as many useful comments as you can in your program to: explain assumptions explain important decisions explain important details explain problems you're trying to solve explain problems you're trying to overcome in your program, etc.

2. literal constant: is a number like 5, 1.23, or a string like 'This is a string' or "It's a string!". It is called a literal because it is literal - you use its value literally. The number 2 always represents itself and nothing else - it is a constant because its value cannot be changed. Hence, all these are referred to as literal constants.
