any shorter way to do this one in python or ruby?

take in two numbers (one line, space-delimieted), convert to binary, and add them as if they were decimal.

input: 13 89
output: 1012102

gets.to_i.times{a,b=gets.split.map(&:to_i);p a.to_s(2).to_i+b.to_s(2).to_i}

61
gets.to_i.times{p gets.split.map{|x|x.to_i.to_s(2).to_i}.sum}

print sum(int(bin(int(i))[2:])for i in raw_input().split())

if just for one pair then
p gets.split.map{|x|x.to_i.to_s(2).to_i}.sum
