title: What is this code: %(var)s ? Python maybe?
body: <p>There is an option on the backend of a website that I use that allows me to customize the data sent in a CSV file when an order has been placed for a product. There are two columns, the left column is where you assign the header and the right column is where you input the variable. The syntax for the existing variables is similar to <code>%(order.random_variable)s</code> or <code>%(item.random_variable)s</code> This looks similar to the string placeholder <code>%s</code> in Python and I'm fairly confident that it is related, if not the same, but I don't quite understand the syntax. Could someone please elaborate on the purpose of this code?</p>
  
  <p>Oh, and for the record, I don't plan on going in and changing variables around right away. Just looking for a good jumping off point for my research into this.</p>
