Well this is not correct in theory because the end should be the max
number, not the number of elements.
So it should be
[i*2 for i in range(10/2)] which might be fine but it's not really

Django makes your life a lot easier in many ways, but you still need some
time to learn it.
The task you're trying it's not trivial though, depending on your
experience it might take a while with any library/framework..

Using a CouchDB server we have a different database object potentially for
every request.
We already set that db in the request object to make it easy to pass it
around form our django app, however it would be nice if I could set it once
in the API and automatically fetch it from there.

I tried also with "ls -lR /" and that definitively takes a while to run,
when I do this:

I have a similar problem, something which I've never quite understood
about subprocess...

We're having some really obscure problems with gzip.
There is a program running with python2.7 on a 2.6.18-128.el5xen (red
hat I think) kernel.
Now this program does the following:
if filename == 'out2.txt':
out2 = open('out2.txt')
elif filename == 'out2.txt.gz'
out2 = open('out2.txt.gz'

I have some complex input to parse (with regexps), and I would like to
create nice objects directy from them.
The re module doesn't of course try to conver to any type, so I was
playing around to see if it's worth do something as below, where I
assign a constructor to every regexp and build an obje

I have some long running processes that do very long simulations which
at the end need to write things on a database.
At the moment sometimes there are network problems and we end up with
half the data on the database.
The half-data problem is probably solved easily with sessions and

We need to be able to reload code on a live system. This live system
has a daemon process always running but it runs many subprocesses with
multiprocessing, and the subprocesses might have a short life...
Now I found a way to reload the code successfully, as you can see from
this testcase:
def
To clarify my "problem", I just thought that assertRaises if used as
context manager should behave as following:
- keep going if the exception declared is raised
- re-raise an error even if catched after the declared exception was catched
I was also confused by the doc a bit:
