Hi list,
I've just encounted something that I found extremely unintuitive and
would like your feedback. This bit me *hard*, causing me to question my
sanity for a moment. Consider this minimal example code (Py 3.10.4 on
Linux x64):
class Msg():
def hascode(self, value):
Aha!
conds = [ lambda msg, z = z: msg.hascode(z) for z in ("foo", "bar") ]
Is what I was looking for to explicitly use the value of z. What a
caveat, didn't see that coming.

It's not a good thing. It means that you have the convenience of
pretending there's no problem,

Based on my background (network and system programming), I'm a bit
suspicious of strings, that is, text. For example, is the stuff that

That makes perfect intuitive sense: 30 hours is 1 day with 6 hours
remaining. In human-speak, we'll say that regardless of whether the
timedelta is positive or negative: we'll say 1 day and 6 hours from now
or 1 day

It's not equally braindead, it follows a simple and logical rule:
Only the day portion is negative.
The more I think about it, the sillier this rule seems to me.
A timedelta is a *whole* object. Either the whole delta is negative or
it is not. It
Hi group,
I'm using Python 3.3.2+ (default, Oct 9 2013, 14:50:09) [GCC 4.8.1] on
linux and have found what is very peculiar behavior at best and a bug at
worst. It regards the mimetypes module and in particular the
guess_all_extensions and guess_extension functions.
I've found that these do not

Doesn't change anything. With this:

it's somewhat OT here, but I have a puzzle to which I would like a

But it's a fun puzzle, so maybe it'll be appreciated here.

in http://docs.python.org/3/reference/datamodel.html#customization the

rather, __lt__() and __gt__() are each other’s
