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"?

Yes, I am, thank you.  However, I didn't want either the keys or the
values.  Instead I wanted to remove a key within a list comprehension.
