SDMX format
Does anyone know of python libs for writing SDMX XML format? http://www.SDMX.org/resources/SDMXML/schemas/v2_0/common thanks, max. -- http://mail.python.org/mailman/listinfo/python-list
Market simulations with Python
I am interested in market simulation with Python, simulating buyers and sellers arriving with goods at random times. I looked at SimPy, it's pretty nice, but all the examples are around congestion problems. Should I a) dig deeper b) write something from scratch c) look at another library? thanks, max. -- http://mail.python.org/mailman/listinfo/python-list
appropriate python version
Sorry if this is a stupid q, I am trying to figure out the appropriate version of Python(2.4 or 2.5) for an XP 64 system running on an Intel Core2 Quad. Python.org has a to a 64bit build, but it specifies Itanium as the target. Should I just be using the regular build? I was also thinking of getting the Enthought edition (http:// code.enthought.com/enthon/) - would their binary work with the setup, and what would be the downside of using it over the special 64bit build? thanks, max. -- http://mail.python.org/mailman/listinfo/python-list
Re: appropriate python version
Thanks. I am guessing the 32bit build should work anyways, same as other 32 progs on XP 64? -- http://mail.python.org/mailman/listinfo/python-list

Hi, I use PKZIP V9.00 and maintain a 2.5GB zipfile that consists of over 6,600 zipped files. There is no problem with reading or writing. Thanks, Jim Which version of Python? What platform? thanks, max -- http://mail.python.org/mailman/listinfo/python-list

Assignment-in-conditional
I am not sure if this came up before, but I would love to have an
'assignment-in-conditional' form in python, e.g
pat = re.compile('something')
if m = pat.match(s):
m.group(1)
Of course there is some concern about accidentally using '=' instead of
'=='. One possible solution is to do what the 'with' statement does:
if pat.match(s) as m:
...
a little ugly but not too much worse that with itself..
what do you guys think?

Thanks for the FAQ, and for the 'casm ;) What do you think about using alternative syntax (something like 'as') - max Fredrik Lundh wrote: xamdam wrote: I am not sure if this came up before, but I would love to have an 'assignment-in-conditional' form in python, e.g it's a FAQ, so it has probably come up before: http://pyfaq.infogami.com/why-can-t-i-use-an-assignment-in-an-expression /F -- http://mail.python.org/mailman/listinfo/python-list
no-setup packages?
Hi all, we have a situation where I need to deploy some python modules without superuser permissions - is there a 'standard' way of doing it? Better yet, is there a way to deploy modules without running any scripts at all? Tarball deployment of some sort? Particular things I have in mind are cx_Oracle, Cheetah. thanks, max -- http://mail.python.org/mailman/listinfo/python-list
