#9 Python - list comprehension

제목 영어로 만드니까 그럴 듯 해서 .. ㅋㅋ

표현 방법들

[표현식 for 변수 in 반복(순회) 가능한 객체]


ex)

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

[i * 2 for i in numbers]

#[2, 4, 6, 8, 10]

[i for i in numbers if i % 2 ==0]

#[2, 4]

 

Well.. I really don't use those expressions that much tho; uhm.......maybe for the time will come.

 

for i in range(len(numbers)):

    numbers[i] = int(numbers[i]) * 2
    
print(numbers)

#[2, 4, 6, 8, 10]

 

However, the list comprehension help your code shorter.
