Some kind of symmetry with get, probably. if
d.get(x)
returns None if x doesn't exist, it makes some kind of sense that
d.setdefault(x)
returns None as well.
Anyone remember why nobody managed to come up with a better name
for setdefault (which is probably the worst name ever given to a method
in the standard Python distribution) ?
(if I were in charge, I'd rename it to something more informative. I'd also
add a "join" built-in (similar to the good old string.join) and a "textfile"
built-
in (similar to open("U") plus support for encodings). but that's me. I
want
my code nice and tidy.)
