It does.

 Indeed, but I was thinking in the context of
    dict_list = [d.pop('a') for d in dict_list]
 and incorrectly expecting to get a list of 'd' without key 'a', instead
of a list of the 'd['a]'.

I apologize if this has already been mentioned in this thread, but are
you aware of "d.keys()" and "d.values"?
  >>> d = {}
  >>> d['do'] = 'a deer, a female deer'
  >>> d['re'] = 'a drop of golden sunshine'
  >>> d['mi'] = 'a name I call myself'
  >>> d['fa'] = 'a long, long way to run'
  >>> d.keys()
  ['fa', 'mi', 'do', 're']
  >>> d.values()
  ['a long, long way to run', 'a name I call myself', 'a deer, a female deer', 'a drop of golden sunshine']
  >>>
