IMO: It's better to use np.zeros(numpy array) to avoid using raw Python array.

That's make sense.

+        public_test = [line for line in lines if line[2] == "PublicTest"]


This 2 line iterate lines twice.
Using if else statement to reduce iteration is better.

@iizukak Thanks. I fixed them. Could you review again?
