Hello,
if I do this:
for row in sqlsth:
________pkcolum ns.append(row[0].strip())
________etc
without a prior:
pkcolumns = [];
I get this error on first iteration:
UnboundLocalErr or: local variable 'pkcolums' referenced before assignment
I guess that's normal as it's the way python works...?!?
My question is: Is there no way to append to a non existing list?
I am lazy for declaring it first, IMHO it bloats the code, and (don't
know if it's good to say that here) where I come from (php) I was used
to not-needing it...
regards,
Yves

Is there a possibility to bring together apache and python in a way that
I can embed python into html?
What do you mean ?
Or even, write a smallish webserver in python (using twisted maybe)
whose only purpose is to serve pages and execute the embedded code...?
My favorite is TurboGears, a collection of modules and glue that brings
together HTTP server(cherrypy ), template(Kid) and SQL object
store(SQLObject ) that can do serious web developement yet don't need to
read a book before starting.
If you just need the server, cherrypy is pretty good and simple to
start. bo****@gmail.co m wrote: Yves Glodt wrote: Which raises another question... :-)

I need this (invalid example-html follows):
<html>
<h1>title of page</h1>
<?py
import time
print "<p>Hello, today is: %s</p>" % (time.ctime())
?>
</html>
Should that not be fairly easy to to, even from scratch, with the
httplib module...?
The advantage would be that I could write a webinterface for my database
and reuse the classes I wrote for the command line app. Or even, write a smallish webserver in python (using twisted maybe)

Ok gonna look into that,

Cheetah template ?
But I like Kid better as I don't want python in HTML, Kid IMO strikes
the balance between python feature and XHTML so the template is still
readable by any XHTML editors.

Which is what I don't like. It should crash.
Perhaps not *crash* as such. Raise an exception perhaps.

Lots of ways. Most of them aren't really Python, but look a lot like
it.
PSP is most like PHP/ASP/etc., and I believe current mod_python's come
with a PSP processor. Be warned that there's more than one thing
floating around by the name Python Server Pages, and they aren't
completely compatible.
Personally, I prefer Cheetah for this, for three reasons:
1) Cheetah doesn't use X/HTML-like syntax for it's tags, so they don't
interfere with my intelligent X/HTML tools.
2) Cheetah can be used for things other than X/HTML, so you get a
twofer on tools. For my last project, I created the Makefile from a
Cheetah template.
3) Cheetah templates are Classes, so you inherit from them. The same
last project created a top-level template that did the site-wide
banner/nav/etc things, and defined abstracd methods for the
title/content. Pages inherited from that (or in some cases from a
subclass of that) and defined concrete versions of the abstrat
methods. Cheetah templates can inherit from Python classes (which I've
found useful), and Python classes can inherit from Cheetah templates
(which sounds useful, but I haven't used it yet).
Or even, write a smallish webserver in python (using twisted maybe)
whose only purpose is to serve pages and execute the embedded code...?
Well, you could always use the CGIHttpServer module that's in the
standard library for this. Cheetah templates can be tested outside the
sever environment, so you don't need a server to execute the embedded
code.

I have created a recordset built from scratch, based on data from an

Any suggestions on what I can use or do to make this possible?

I have an append query that needs to run every time a line item is
added to a subform. The append writes to a table that is the source
for a pull down box. Problem is that it takes 5 seconds to run. This
makes adding lines to an order too slow for the users. The result of
the query provides real time availabilty, so I really do need this to
work.
The tblJobs has only 10,000 records, tblJobsLineItems has 150,000
records.

Cheers,
I've been struggling all day today with this, maybe you could give me some
useful pointers.
I would like to (elegantly) concatenate a string out of all node values in
a map. I have to do it without using boost (as it is forbidden to use it
in our project).
(Forgive me for giving a non-compiling code.)
