tuple

# tuple -> immutable!

#1. count, index, map

for i in range(2):
    a = tuple(map(int, input().split()))

    if a.count(30) > 0:
        print(a.index(30))
    else:
        print('Not Found')
        
====Result====
1 3 6 8
Not Found
2 5 4 20 30
4

 

#2. tuple 표현식

• tuple(식 for 변수 in 리스트 if 조건식)

a = tuple(i for i in range(10) if i%3 == 0)
print(a)

b = tuple(i+3 for i in range(6) if i%2 == 0)
print(b)

====Result====
(0, 3, 6, 9)
(3, 5, 7)
