Question

I have an object that can’t be dumped by simplejson, so I need to create a list from it first. Currently this is what I’m using:

    messages = h.flash.pop_messages()
    items = []
    for message in messages:
        item = {}
        item['category'] = message.category
        item['message'] = message.message
        items.append(item)

I feel like there is a more pythonic way for me to be doing this, can anyone shed some light?

Edit:

As requested, this is the class for the Message object:

class Message(object):
    """A message returned by ``Flash.pop_messages()``.

    Converting the message to a string returns the message text. Instances
    also have the following attributes:

    * ``message``: the message text.
    * ``category``: the category specified when the message was created.
    """

    def __init__(self, category, message):
        self.category=category
        self.message=message

    def __str__(self):
        return self.message

    __unicode__ = __str__

    def __html__(self):
        return escape(self.message)

Answer 1

items = [{'category': m.category, 'message': m.message}
  for m in h.flash.pop_messages()]
