Content Templates [#747818]

I am really new to this so this might seem stupid but I have this really simple code to display my content in a table

Περιγραφή	Τιμή
`print $node->field_description[0]['view']`	`print $node->field_price[0]['view']`
`print $node->field_description[1]['view']`	`print $node->field_price[1]['view']`
`print $node->field_description[2]['view']`	`print $node->field_price[2]['view']`
`print $node->field_description[3]['view']`	`print $node->field_price[3]['view']`

If I only have 4 elements in my table this is fine but what if I want to create more data everytime I need more code. I think what I need is a way to use a variable for the number of elements each time so I can create exactly the number of rows I need.
Can anyone help?
