Udemy : Python 커피 머신 프로젝트

Udemy : Python 커피 머신 프로젝트

3개 종류의 커피들이 주어진다

필요한 재료와 금액이 주어진다

• 유저는 어떤 커피를 마실지, 그리고 동전 얼마를 넣을지 입력을 한다
• 입력에 따라, 재료가 부족하든지, 금액이 부족하든지, if문을 넣었다
• 여기서 제일 집중했던 것은 함수를 만드는 것이었다
  • is_sufficient : 안에 재료가 적당히 있는지 확인하는 함수
  • make_coffee: is_sufficient가 True를 반환하면, 커피를 만드는 함수이다
  • money_change: 금액을 계산하는 함수이다
• 함수를 사용해서, 2개 이상의 변수를 반환했다
  • 튜블로 반환이 되어서, 인덱스를 통해, 내가 원하는 데이터를 활용했다
