Minimum Scalar Product

According to this Code Jam problem, I try to made it in one line.

code.py

min_scalar = '\n'.join(
                 'Case #{0}: {2}'.format(
                     test+1,
                     input(),                     # from test case, the value describe length has no use in python.
                     sum(a * b for a, b in zip(
                         sorted(int(v) for v in input().split()),
                         sorted(int(v) for v in input().split())[::-1])))
                 for test in range(int(input())))
