title: Reading data from file with Python-special format
body: <p>I have one problem. I have some data file which structure is that:</p>
  
  <p>first line</p>
  
  <pre><code>219,241,280,369,402.7,472.7,520,553.3,588.7,635.3,678.7,734.7,795.3,880,914,968.7,1030.7,1085.3,1185.3
  </code></pre>
  
  <p>second line</p>
  
  <pre><code>436.5,430.5,426,418,420,413.3,410,406.7,404,402,407.3,410,413.3,418.7,420,428,433.3,440.7,458.7
  </code></pre>
  
  <p>In first line are values of x and in second line are values of y.
  Now I want these values ​​to get into this shape:</p>
  
  <pre><code>x=r_[219,241,280,369,402.7,472.7,520,553.3,588.7,635.3,678.7,734.7,795.3,880,914,968.7,1030.7,1085.3,1185.3]
  
  y=r_[436.5,430.5,426,418,420,413.3,410,406.7,404,402,407.3,410,413.3,418.7,420,428,433.3,440.7,458.7]
  </code></pre>
  
  <p>I have a problem with the addition of r_.
  Any suggestion?</p>
