The reason for the ugly hasattr() calls is that object itself defines
the comparison operators (in Python 3.0a2).

Or will the signature change to match the one provided by codecs?
codecs.open(filename, mode[, encoding[, errors[, buffering]]])
using the logic described above regarding mode?
Or some other way?
Thanks!

greater than -4 or less than precision, decimal format otherwise."
There is no "decimal format", but there is "Signed integer decimal"
format which is what seems to being used.
So is this a doc bug?
BTW I notice that deci
is possible to do so.
I'll write myself a class decorator that can create the "missing"
comparisons using logical equivalences.
Thanks!

I think
re.replace() is better and more consistent regarding the rest of the
library.
And as for subn, well, replacen or substituten are possible, but why not
have just one method and have an optional keyword argument if a tuple is
wanted?

rted data structures are used far more frequently than the unsorted
versions.
If you primarily program in Python, using dict + sorted() is very
natural because they are built into the language. But using a sorted
data structure and never sorting is a very common practice in other

If there is a positive response I will submit it to the PEP editors. If
there is not, I will just hope that someone else will pick up the idea,
even if in another form or with a different API, because I'
. I'm
happy to do that (at least for a sorteddict), but if someone who has
done PEPs before did so, I'd be just as happy---I'll see what the
feedback is (if any) when I get online again next week.
PS And no, I've never programmed in PHP and never fancied doing so:-)

I would suppose that it would be better if it was implemented in C---for
example, my own pure Python ordered dict takes about eight times as long
to load in 18,000 items compared with loading the same into a dict.
