title: Write the digits of a number into an array
body: <p>I want to calculate with seperated digits of a very long number. How can I do this in Python2.7? I thought about somehow write the digits in an array so that I can access the digits with array(x):</p>
  
  <pre><code>number = 123456789123456789
  array = [1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9]
  </code></pre>
  
  <p>The problem is, that the number has so many digits, that it would take very long to do that manually. So how can I do this automatically?</p>
