title: Method for reading a string of coordinates and taking out intgers (Python)
body: <p>Lets say that I have a string that represents points on the <code>x, y</code> axis "<code>(1,2), (10,20), (100,200)</code>" what is the best method of abstracting the coordinate integers for numerical analysis? </p>
  
  <p>So this is kind of a two part question --</p>
  
  <p>First which form is the best for math/scientific computing purposes?
  (e.g. a list of lists <code>[[1,2], [10,20]...</code>, OR two lists <code>x = [1,10,100] y = [2,20...</code>, OR dictionary OR some other form?) </p>
  
  <p>Second what is the best Python way to obtain that form?</p>
  
  <p>Thanks in advance!</p>
  
  <p>PS if there is an easy answer to this in numpy or scipy I would love to know, but I would also like to know how to solve it without using either.</p>
