Hi folks.
I want to build a pair of wheels - one for numpy, one for scipy. And
I want to statically link atlas (with blas and lapack) into these
wheels. I don't want to statically link numpy or scipy into the
Python interpreter.
The goal is to decrease the frequency with which new wheels need t

I believe I heard that the PEP 484 type checker is to go into CPython 3.5.
Since type annotations have been there since 3.0, is it at all likely
that CPython versions < 3.5 will also be supported by this checker?
Thanks!

I have no idea about the protocol used by NI DataSockets, but you
might be able to reverse engineer the protocol by using the official
client with a sniffer.
Also, be aware that TCP/IP guarantees that you get the correct data in
the correct order, but it doesn't guarantee anything about the sizes
IMO, it's usually better to test for features and use them if they are
present, than to build a list of features available in specific
interpreters.
I see it as analogous to the difference between huge C #ifdef's on OS,
and autoconf.

Do you perhaps mean:
cmd = 'ethtool %s' % (interface, )

Is there an opensource Python tool for creating RSS feeds, that doesn't
require large dependencies?
I found feedformatter.py on pypi, but it seems a little old, and its sole
automated test gives a traceback.
Is there a better starting point?

"except" catches any exception that inherits from its argument, and all
MySQL exceptions inherit from MySQLError, so something like this will
catch only MySQL exceptions and nothing els

Two methods:
1) If you need your hash only once in an infrequent while, then save
the elements in a list, appending as needed, and sort prior to
hashing, as needed
2) If you need your hash more often, you could keep your elements in a
treap or red-black tree; these will maintain sortedness through

How safe is this? I like the idea.

now I can have comments, again, too
x = ''"hello"'' # now x contains two double-quote characters
I'm sure that the implementation is trivial, and it's so much easier to
write strings that contain quotes (not to mention how easy it is to read
those strings back later).

Not quite: "import pickle" merely readies the machinery that objectifies
pickles. In order to objectify a pickle, you have to call pickle.loads:
>>> import pickle # get ready to objectify
quot;with" statement, though, these loops are slowly
disappearing.
