enumerate()
In Python, a for loop is usually written as a loop over an iterable object. This means you don’t need a counting variable to access items in the iterable. Sometimes, though, you do want to have a variable that changes on each loop iteration. Rather than creating and incrementing a variable yourself, you can use Python’s enumerate() to get a counter and the value from the iterable at the same time! https://realpython.com/python-enumerate/

range()
 정수만 받아. 그리고 최대 3가지의 파라미터?를 혹은 argument인가? (정확한 이름 확인하기)를 받을 수 있어. 즉 시작하는 숫자, 끝나는 숫자, 그리고 step. 

len()
 길이를 뜻해. 숫자로 표시됨.
