title: python loadtxt to read delimited file
body: <p>I am just switching from Matlab to Python, and would like to learn how to read this file in Python using <code>loadtxt</code> from <code>numpy</code> package. (I use <code>textscan</code> in <code>Matlab</code> to read it)</p>
  
  <pre><code>"07220S006","14/01/12 01:59:50",10,"0"
  
  "07220S006","14/01/12 02:00:00",10,"0"
  
  "07220S006","14/01/12 02:00:10",10,"0"
  </code></pre>
  
  <p>I am able to use the <code>split</code> function in Python regular expression package to read this file in, however, given my data containing about a few hundred thousands of lines like these, the <code>split</code> function applied on each single line will result in a significant analysis time. So I think <code>loadtxt</code> will do a better job in this case. I have found a number of solutions to read similar file, but this file is much more complicated than those examples and I got no idea how to read it.</p>
  
  <p>Any help and recommendation is appreciated</p>
