zip() boleh mencipta iterable dengan menggabungkan berbilang iterable seperti yang ditunjukkan di bawah:
*Memo:

  • Iterable berhenti apabila input terpendek leterable habis.
  • Iterable tidak boleh diakses terus dengan indeks jadi gunakan list() untuk mengaksesnya dengan indeks.
fruits = ["Apple", "Orange", "Banana", "Kiwi", "Lemon", "Mango"]
meats = ["Chicken", "Beef", "Pork", "Duck", "Mutton"]
vegetables = ["Onion", "Carrot", "Garlic", "Spinach", "Eggplant"]

print(zip(fruits, meats, vegetables))
# <zip object at 0x7da5876aaa40>

print(zip(fruits, meats, vegetables)[0])
# Error

print(list(zip(fruits, meats, vegetables)))
# [('Apple', 'Chicken', 'Onion'),
#  ('Orange', 'Beef', 'Carrot'),
#  ('Banana', 'Pork', 'Garlic'),
#  ('Kiwi', 'Duck', 'Spinach'),
#  ('Lemon', 'Mutton', 'Eggplant')]

f, m, v = list(zip(fruits, meats, vegetables))[0]
print(f, m, v)
# Apple Chicken Onion

for f, m, v in zip(fruits, meats, vegetables):
    print(f, m, v)
