Thank all for the discussion. Maybe I can separate my question into two. First, I have experience in Matlab, where I can use "eval". I wonder whether someone knows about it.
Second, if I just want to return data[:,1], ...data[:,-1] separately without knowing ahead how many columns data has. What should I do?
