What is "generator object" in django?

Am using Django voting package and when i use the method get_top() in the shell, it returns something like "generator object at 0x022f7AD0, i've never seen anything like this before, how do you access it and what is it?

my code:

v=Vote.objects.get_top(myModel, limit=10, reversed=False)
print v
<generator object at 0x022f7AD0>

NB: I thought get_top will just return a nice list of myModel, which i can do something like v.name etc

From stackoverflow

• If you want a list, just call list() on your generator object.

  A generator object in python is something like a lazy list. The elements are only evaluated as soon as you iterate over them. (Thus calling list on it evaluates all of them.)

  For example you can do:

  >>> def f(x):
  ...  print "yay!"
  ...  return 2 * x
  >>> g = (f(i) for i in xrange(3))    # generator comprehension syntax
  >>> g
  <generator object <genexpr> at 0x37b6c0>
  
  >>> for j in g: print j
  ... 
  yay!
  0
  yay!
  2
  yay!
  4
  

  See how f is evaluated only as you iterate over it. You can find excellent material on the topic here: http://www.dabeaz.com/generators/

• Hmmmm

  I've read this and this and things are quiet clear now;

  Actually i can convert generators to list by just doing

  mylist=list(myGenerator)
  

• A generator is a kind of iterator. An iterator is a kind of iterable object, and like any other iterable,

  You can iterate over every item using a for loop:

  for vote in Vote.objects.get_top(myModel, limit=10, reversed=False):
      print v.name, vote
  

  If you need to access items by index, you can convert it to a list:

  top_votes = list(Vote.objects.get_top(myModel, limit=10, reversed=False))
  print top_votes[0]
  

  However, you can only iterate over a particular instance of an iterator once (unlike a more general iterable object, like a list):

  >>> top_votes_generator = Vote.objects.get_top(myModel, limit=3)
  >>> top_votes_generator
  <generator object at 0x022f7AD0>
  >>> list(top_votes_generator)
  [<Vote: a>, <Vote: b>, <Vote: c>]
  >>> list(top_votes_generator)
  []
