title: How do I split on the second " , "
body: <p>I am trying to split on the second,</p>
  <pre><code>file = open()
  dictionary = {}
  for linje in filen:
      bites = linje. split()
      month = bites[0]
      temp = bites[0]
      dictionary[month] = temp
  print(dictionary)
  </code></pre>
  <p>The file looks like this:</p>
  <pre><code>Jan,1,2.7
  Jan,2,2.8
  Jan,3,0.7
  Jan,4,1.8
  Jan,5,1.2
  ...... each day every day of the year.
  </code></pre>
  <p>If I write <code>split(&quot;,&quot;)</code> the output becomes this in my dictionary:</p>
  <pre><code>{Jan : Jan}.
  </code></pre>
  <p>If I don't split it becomes like this:</p>
  <pre><code>{Jan,1,2.7 : Jan,1,2.7}
  </code></pre>
  <p>I want it to be like this:</p>
  <pre><code>{Jan,1: 2.7}
  </code></pre>
