  <p>Now what i want to read is the first value from each process in each {} block,for example in process numbered 2 I want to read -10.4392 from {-10.4392,-10.4392,...} and store it to a listand from the same line I also want to read -0.911365 from {-0.911365,-0.916462,...}and store it to separate list.This Pattern is to be followed on each processs. Any idea on how to do it in python 3.</p>
