My function gets an iterable of an unknown type. I want to check whether it's
ordered. I could check whether it's a `set` or `frozenset`, which would cover
many cases, but I wonder if I can do better. Is there a nicer way to check
whether an iterable is ordered or not?
Thanks,
Ram.

Terry, that doesn't really answer the question "why", it just pushes it back to
the documentation. Is there a real answer why? Why return NaN when Inf would
make mathematical sense?

While debugging my code I found that the bug was because I assumed that
something like `divmod(float('inf'), 1)` would be equal to `(float('inf'),
float('nan'))`, while Python returns `(float('nan'), float('nan'))`. Why does
Python make the division result be NaN in this case? `float('inf') / 1`
Hello everybody! I have a question.
I have a Django app running on Heroku. I need to run about 100 worker threads
there to do uploads/downloads simultaneously. A Heroku Dyno has only 512MB of
memory, so I'm reluctant to run 100 worker threads. (I've had Dynos crash from
lack of memory when usi
Hi all,
If I want to acquire a `threading.Lock` using the context manager protocol, is
it possible to specify the `blocking` and `timeout` arguments that `acquire`
would usually take?
Thanks,

Here's the offending MSI, if anyone wants to investigate:

doing in the Python MSI. (I'm guessing it's timezone-related, but it's still
far-fetched, because why would an obscure time zone file appear in the MSI log?)

Hi everybody,
I need to install Python 3.4 final urgently, because my IDE stopped supporting
Python 3.4 beta2, and I need it urgently to work.
I downloaded it, but the MSI won't install. It didn't work on both of my
computers (Windows 7 64bit).
I managed to have the MSI dump data to log, file
Hi,
I'm curious. If I append an item to a list from the left using `list.insert`,
will Python always move the entire list one item to the right (which can be
super-slow) or will it check first to see whether it can just allocate more
memory to the left of the list and put the item there, saving
Hi,
I'm trying to install Python 3.4b3 on Ubuntu. Since compilation seems to be the
only way, I'm trying that.
I downloaded the source, I changed Setup.dist to have this:

Hello,
I wanted to announce that I have just released my little side project,
PythonTurtle.
Here is its website:
http://pythonturtle.com
Its goal is to be the lowest-threshold way to learn (or teach) Python.
You can read more about it and download it on the website.
Ram.
