If your desired result is a list whose elements are bound to different
dictionaries, it won't be necessary to bind a dictionary to a variablename
and the bind a copy of it to an new element of a list.
So the shoretest way for me is to append an explicit new dictionary
at the end of list, assumed that your dictionary is as easy as shown
in your example.
So the following works for me so far:

>>> myList=[]
>>> for i in range(3):
... 	myList.append({'id':i})
... 	
>>> myList
[{'id': 0}, {'id': 1}, {'id': 2}]
>>>
