What is meant by DRY
DRY stands for "Don't Repeat Yourself " that means you should not have the same piece of code twice (or more ) in your program. If this is needed, you can make a function from this piece of code
Don't repeat yourself I. e. never copy & paste the same peace of code in your program, but create a function from it and reuse the function
When you will need some function more than one time, make sure this function use 'return'
