Python의 zip

커피 사주세요주의!

zip()은 아래와 같이 여러 iterable을 결합하여 iterable을 생성할 수 있습니다.
*메모:

• 가장 짧은 입력 iterable이 소진되면 iterable이 중지됩니다.
• iterable은 인덱스로 직접 액세스할 수 없으므로 list()를 사용하여 인덱스로 액세스합니다.

fruits = ["Apple", "Orange", "Banana", "Kiwi", "Lemon", "Mango"]
meats = ["Chicken", "Beef", "Pork", "Duck", "Mutton"]
vegetables = ["Onion", "Carrot", "Garlic", "Spinach", "Eggplant"]
