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?
