List, Set, Range

🍉 List

---

✔️ *

N = [1, 2, 3, 4, 5]

print(*N)

>> 1 2 3 4 5

N = [[1, 2, 3], [4, 5, 6]]

print(*N)

>> [1, 2, 3] [4, 5, 6]

✔️ 변수 할당

x, y, z = [1, 2, 3]

>> x =  1 ,  y =  2 ,  z =  3

x, y, z = [1, 2, 3, 4, 5]		# 할당할 변수 부족으로 에러 발생

>> ValueError: too many values to unpack (expected 3)

x, y = [[1, 2, 3], [4, 5, 6]]

>> x = [1, 2, 3] 
>> y = [4, 5, 6]

🍉 Set

✔️ *

N = set([1, 2, 3, 4, 5])

print(*N)

>> 1 2 3 4 5

✔️ 변수 할당

a, b, c, d, e = set([1, 2, 3, 4, 5])

✔️ *

N = range(5)

print(*N)

✔️ 변수 할당

a, b, c, d, e = range(5)

print(a, b, c, d, e)
