<p>How to return sum of hours from txt file?</p>

Georgy,30,30,29.5,5
Addi, 20,20,20
Lisy,16,16,20

result:</p>

<pre><code>Willy:137

<h1>Update</h1>

<p>I would like to be able to sum hours by name, ie: given the following data (note the two occurrences of <code>Willy</code>, I should achieve the same results as above:</p>

<pre><code>Willy,10,37,20
Georgy,30,30,29.5,5
Addi, 20,20,20
Lisy,16,16,20
Willy,40,30
</code></pre>
