title: How to split a float number string into two lists?
body: <p>I have the string <code>'1234.12'</code> and I want to split it into two lists: <code>[1234]</code> and <code>[12]</code>.</p>
  
  <p>The only way I know is to make the whole string into a list by using <code>.split()</code> with a comprehension: <code>[n.split() for n in '1234.12']</code>, which gives me: </p>
  
  <pre><code>[['1'], ['2'], ['3'], ['4'], ['.'], ['1'], ['2']]
  </code></pre>
