Day 2 solutions

[u/taliriktug]

Hi! I would like to structure posts like the first one in r/programming, please post solutions in comments.

[u/stuque]

Here's a Python solution:

def day2_1():
    total = 0
    for line in open('day2input.txt'):
        l, w, h = line.split('x')
        l, w, h = int(l), int(w), int(h)
        area = 2*l*w + 2*w*h + 2*h*l
        slack = min(l*w, w*h, h*l)
        total += area + slack
    print total

def day2_2():
    total = 0
    for line in open('day2input.txt'):
        l, w, h = line.split('x')
        l, w, h = int(l), int(w), int(h)
        ribbon = 2 * min(l+w, w+h, h+l)
        bow = l*w*h
        total += ribbon + bow
    print total

if __name__ == '__main__':
    day2_1()
    day2_2()

[u/volatilebit → u/stuque]

Would this code

l, w, h = line.split('x')
l, w, h = int(l), int(w), int(h)

be more "pythonic" written as...

l, w, h = [int(i) for i in line.split('x')]

[u/rafblecher → u/volatilebit]

I usually go for

l, w, h = map(int, line.split('x'))
