📌 memo

• 문자열 인덱싱 : https://wikidocs.net/2838
  year = date[0:4]
  month = date[5:7]
  day = date[8:10]
  
• 문자열 슬라이싱 : https://wikidocs.net/2839
  year, month, day = date.split('.')
  
• 형변환 :
  string to int : int()
  int to string : str()
• for문 형태 :
  for i in range(0, len(list)):
for i in range list:
  
• int형으로 slice후, 배열 만들기

my_list = list(map(int, my_str.split('.')))

• list를 dictionary(hash)로 만들기

term_dict = {key : value for idx in list}
