day 1 Python/Julia

#Python
left, right = map(sorted, zip(*[map(int, line.split()) for line in open("input.txt)]))
print(sum(abs(i-j) for i,j in zip(left,right)))
print(sum(i*right.count(i) for i in left))

#Julia
using DelimitedFiles
left, right = map(x -> sort(readdlm("input.txt", Int)[:, x]), 1:2)
println(sum(abs, left-right))
println(sum(i * count(x -> x == i, right) for i in left))
