title: How to sort by a particular attribute of a class?
body: <p>I have a model with an attribute which keeps track of the price. Right now, I have a list of that certain model. Is there anyway to rearrange the list to sort by that particular attribute? Is python smart enough to know that the attribute is a value which can be sorted? I am not keeping keeping track of the instances of a particular model using a database (it is not needed for what I am doing, so I cannot just retrieve the instances from the database in sorted order)
  Thanks!</p>
