Listening to 'Radio Free Python' episode 8
(http://radiofreepython.com/episodes/8/ - around about the 30 minute mark) I
heard that Python pre creates some integer constants to avoid a proliferation
of objects with the same value.
I was interested in this and so I decided to try it out.
First I
Thanks for all the replies. I hadn't thought about the opportunities that exist
for optimization when the whole script is there (or when compound operations
are taking place) by contrast with plain old REPL ops.
I liked your code Chris demoing the different ranges in different versions. I
tried
I'm interested in best practice approaches to : decoupling data access code
from application code; and translations between database structures and domain
objects.
For some time I've done database access by in a particular way and while I
think it's OK it's not very pythonic so I'd be intereste
One reason you may be having difficulty is that unlike some languages
(C++/Java) object-orientation is not a be all and end all in Python, in fact
you could work with Python for a long time without really 'doing it' at all
(well other than calling methods/properties on existing API's). Having sa

Good question !
I'm not anti-ORM (in fact in many circs I'm quite pro-ORM) but for some time
I've been working with a client who doesn't want ORMs used (they do have quite
good reasons for this although probably not as good as they think).
Hi - I have a script which instantiates a SimpleXMLRPCServer server and which I
use to simulate a 'real server' when developing client scripts which will
eventually get used with the 'real server'.
I would like to stop the script running in response to a CTRL-C.
The script is run on windows.

Hi - I have some images which I would like to remove specks from using
the PIL. I would like to be able to say that if a pixel is in a blob of
less than n contiguous pixels then all pixels in that blob should be
removed.
The images are 8 bit images with only 0 and 255 values.
I can think of quite
Hi - I have written some python to insert a row into a table using
MySQLDB. I have never before written SQL/Python using embedded
parameters in the SQL and I'm having some difficulties. Could someone
point me in the right direction please ?
The python looks like this :
import MySQLdb
import MySQL

Hi - Feeling a bit weird about this but I cannot find the 'begin'
method on a connection object of MySQLdb. Can anyone explain why ?
I'm using version 1.2.0 which is pretty recent and I've read that
'begin' should be a method of connection but it's not there ! Feeling
pretty puzzled !
Below are t
"What do i expect the begin method to do" ?
Explicitly start a transaction (and therefore suppress autocommits) in
an environment where autocommit is on.
No i haven't read the pep, thanks for that.

For instance in ...
http://pypi.python.org/pypi?%3Aaction=search&term=spam&submit=search
... 'bud.nospam 1.0.1' has a score of 9 but 'pydspam 1.1.9' has a
score of 7.
Where are those numbers from and what do they mean ?
Thanks

Hi - PEP8 says lines should not exceed 79 characters in length
( http://www.python.org/dev/peps/pep-0008/ ).
So if you've got some code that looks like this :
raise fooMod.fooException("Some message which is quite long")
... and assuming a certain amount of indenting you're going to break
that g

Hi - I was just trying to install the Python debugger pudb (http://
pypi.python.org/pypi/pudb) and easy install fell over saying it
couldn't find a module termios.
It turns out termios is only for Unix (http://docs.python.org/library/

Does anyone know of way around this ? Is there

Hi - I've got a straightforward class I want to serialize as JSON
(actually I want to a serialize a list of them but I believe that's
irrelevant).
I've subclassed JSONEncoder and defined my own version of the
'default' method ( based upon what I read at

)
