I have data in a csv file e.g <pre><code>1,2,3,4 4,5,6,7 </code></pre> what I want is to create an extra column that sums the first rows so that the result will look like. <pre><code>1,2,3,4,10 4,5,6,7,22 </code></pre> And an extra row that sums the columns. <pre><code>1,2,3,4,10 4,5,6,7,22 5,7,9,11,32 </code></pre> This is probably really basic but I could do with the help please?

2. COIf you dont want to go with a certain python library (say you want to get python practice) you could just import the csv file as a 2D list and then generate the sums, append your lists and export the 2D list again.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
