where is uno?
I'm using SUSE 10.3 have installed OpenOffice Python interface from the distro DVD. But still I need help because I can't import uno. And that's because it's not in my site-packages. I read about how to use it and have reviewed code that uses it but no where did any of the articles explain where to retrieve the actual 'uno' py package. Can someone provide a hint?

Re: Which Object Database would you recommend for cross platform application?
Thomas Ploch wrote: Hello folks, I am currently developing an open source Event Managment software (events in real-life, like concerts, exhibitions etc. :-) ) using wx for the GUI, and I need an Object database. Since this is the first time I actually need doing this, I wondered if anybody here could recommend one. It can be fairly simple. It doesn't need threading support and will only host one client (the application, but I am thinking about making this database accessible via the web, but this is still far in the future), although the database might get big (around 1GiB). It should be available for linux, mac os and windows. I looked into ZODB, but thats totally overloaded for my purpose. I looked into Durus (a re-implementation of ZODB, but without this overloaded stuff, but the documentation is very thin). Both of them don't really appeal. So I wondered if any of you could recommend one that (more or less) best fits the described conditions. Thanks in advance, Thomas This answer does not really answer your question. But have you looked a dabo (www.dabodev.com). It doesn't support the web (yet) but you said that's in the furture. Dabo was built for this type of app. Dabo supports Postgres,MsSQL,MySQL,Firebird, and SQLite. Non of the DB's are what I'd call an object database but is that a real requirement? BTW the first 4 DB's can support 1GB and more. Johnf -- http://mail.python.org/mailman/listinfo/python-list

That's true even on multiprocessor machines, not only because there's almost nothing to compute but only IO traffic. CMIIW. Using multiplexing, you'll get good results with simple code without the danger of deadlocks. Have a look at asyncore (standard library) or the Twisted framework -- personally, I prefer the latter.

Re: I want to see all the variables
Steven D'Aprano wrote: There are three other underscore conventions in use: (1) Objects with a single leading underscore like _attribute are private by convention, but Python doesn't enforce it. Starting an object with a single underscore is like writing # Private! Don't touch! after it. (2) By convention, if you want to create a name that is the same as a built-in object without shadowing (hiding) the built-in, put a single trailing underscore after it like file_. That's just a style convention though, you are free to call it FiLE ,or anything else, if you prefer. (3) Last but not least, class attributes with two leading and trailing underscores are considered special but public, like __init__ and __repr__. It is probably a bad idea to invent your own. Very detailed. But I was attempting to debug some code which subclassed other code. I got a traceback that something like no mySubClass.__source.query() did not exist. The superclass had something like myClass.__source.query(sql) which worked but mySubClass.__source.query(sql) did not work. So I tried to debug using dir(myClass.__source) and got an error. And I also got error when I dir(mySubClass.__source. So how could I have debugged the problem if dir() will not display information on the __source? I hope that explains my issue.

Re: INSERT statements not INSERTING when using mysql from python
Ben wrote:
I don't know whether anyone can help, but I have an odd problem. I have
a PSP (Spyce) script that makes many calls to populate a database. They
all work without any problem except for one statement.
I first connect to the database...
self.con = MySQLdb.connect(user=username, passwd =password)
self.cursor = self.con.cursor()
self.cursor.execute(SET max_error_count=0)
All the neccesary tables are created...
self.cursor.execute(CREATE DATABASE IF NOT EXISTS +name)
self.cursor.execute(USE +name)
self.cursor.execute(CREATE TABLE IF NOT EXISTS networks (SM
varchar(20),DMC int,DM varchar(50),NOS int,OS varchar(50),NID
varchar(20))
Then I execute many insert statements in various different loops on
various tables, all of which are fine, and result in multiple table
entries. The following one is executed many times also. and seems
identical to the rest. The print statements output to the browser
window, and appear repeatedly, so the query must be being called
repeatedly also:
print pbSQL query executing/bp
self.cursor.execute(INSERT INTO networks VALUES ('a',' +i+
','c','2','e','f','g'))
print pbSQL query executed/bp
I have, for debugging, set i up as a counter variable.
No errors are given, but the only entry to appear in the final database
is that from the final execution of the INSERT statement (the last
value of i)
I suspect that this is to vague for anyone to be able to help, but if
anyone has any ideas I'd be really grateful :-)
It occured to me that if I could access the mysql query log that might
help, but I was unsure how to enable logging for MysQL with python.
Cheers,

Not sure this will help but where is the commit? I don't use MySQL but

Is there anything that will show all the private vars and functions? johnf The idea of the underscore items is that they aren't to be used by you. Double leading+trailing underscore attributes are NOT private, they are *special* but public (e.g. __dict__, __class__, __str__, etc.). If you don't believe me, have a look at dir(int) and count the underscored attributes listed. Then try to find __dict__, __name__, __bases__, __base__ or __mro__ within the list. Why are they suppressed? But even if underscored attributes were private, the Python philosophy is that private attributes are private by convention only -- even name-mangled __private methods can be reached if you know how. If you wish to access private variables and functions you will almost certainly have to look at the source code to make sure of what they are and how they can be utilized. Not so. class Parrot(object): ... def _private(self): ... Private method, returns a magic string. ... return Don't touch!!! ... Parrot._private.__doc__ Private method, returns a magic string. Ok then how do debug when I have something like __source and I need to know what is available for the object? John -- http://mail.python.org/mailman/listinfo/python-list

Re: your opinion about psycopg vs pygresql
Martin P. Hellwig wrote: Hi all, I'm playing a bit with PostgreSQL, in which I've set me the target to create a python script which with user input creates a new user role and a database with that owner (connecting to template1 since I know that at least that db exists). Ok so I installed PostGreSQL and pygresql since it looked like that this is endorsed by PG, I had some trouble with the DB-API2 (complains about there is already a connection to template1, even when I closed and deleted the connector) so I solved it by using the pg api. But I was intrigued by this problem and started googling and by that time I've noticed that python projects like Django seem to favor the psycopg module. So I installed that one (the 1.1 version, since Django uses that too) and it looked like it has the same problem of creating a user after a database, I'm sure that there is a user error in there somewhere :-) However, given the choice, what in your opinion would be the reason why someone would chose one over the other? Now I know this could easily get into a flamewar, so if you comment (but please do so) I'll still investigate that, since at this moment I don't even have a clue how they differ and on what reason, why does PostgreSQL seem to favour pygresql and Pythoneers psycopg? Thanks in advance. I have not used pygresql but I see it often as a standard package with the SUSE DISTRO. But I use Psycopg 2. I find that it is very fast and provides a few extentions that I have used. Reported bugs are fixed immediately. John -- http://mail.python.org/mailman/listinfo/python-list

Re: Python and CMS

So I wondered if there where any in python. Sadly, I only found Plone, skeletonz, and PyLucid (If there is any more, please let me know). Of those three, only PyLucid supports WSGI and it didn't look very nice to me. Both Plone and skeletonz looked very nice. However, they can't be hosted on a regular web host(at least to my knowledge) since they run as the web server themselves. So hosting would cost more, at least 2-3 times more from what I've seen. So I'm thinking of making a python CMS based on WSGI. I'm now trying to figure out a few things like the best way to store the content and how to manage/use plugins. For storing the content, the only ways I know of are as files or in a database. But I'm not sure what would be better. And as for how to do plugings, I plan on looking at Plone and skeletonz. As for working with WSGI, I have found Colubrid(http://wsgiarea.pocoo.org/colubrid/) and Paste(http://pythonpaste.org/).
