I don't doubt that there might good reasons for that, but

Thanks to this thread, and after a bit of reading, I've finally managed to
discover that in Python there are class attributes and instance attributes,
the former working similarly to C++'s static member variable
I have a list, songs, which I want to divide into two groups.
Essentially, I want:
new_songs = [s for s in songs if s.is_new()]
old_songs = [s for s in songs if not s.is_new()]
but I don't want to make two passes over the list. I could do:
new_songs = []
old_songs = []
for s in songs:
if s.

OK, we've all done it by accident (especially when starting out), but
are there people that rebind builtins intentionally?

Hmm. Would this serve?
old_songs = songs[:]
new_songs = [songs.remove(s) or s for s in songs if s.is_new()]
Python doesn't, AFAIK, have a "destruct

Many long-time posters have advised "Don't rebind built-in names*.

wrapping print to modify some aspect of its operation than one cannot do
with its keyword parameters. The point for this post is that such
wrapping modify or
