In Python 2.4 you have to use some third party module. There is no
other option for _invalid_ HTML. IMHO BeautifulSoup is the best among
them.

I only want to know about sqlobject. I don't want any of sqlobject's
dependencies, such as MySQLdb, pysqlite2, psycopg2 etc. which
modulefinder shows also.
And as far as I can tell, modulefinder needs a Python script, but its
much easier for me to find a package&#x

But `bools` are usefull in some contexts. Consider this:
>>> 1 == 1
True

0

False

-1
At first look you can see that `cmp` does not return boolean value
what not for all newbies is so obvious.

We have released an update to the PyDSTool dynamical systems and

are lots of minor improvements and fixes in this version, but a
powerful new feature is the support for user-defined functions for

I don't know exactly why in this case Popen doesn't work,
but the counterpart of os.system is Popen with option shell=True
and the first parameter should be a string instead of list.
That seems to work:
proc = Popen("wget -nv -O dir/cpan.txt http://search.span.org";,
shell=True, stdout=PIPE, stderr=PIPE)
and this variant seems to work too:
cmd_set = ['wget', '-nv', '-O', 'dir/cpan.txt', 'http://search.span.org']

Actually, I wanted to use Treeview, so I needed to tweak
a little bit this code, but it's very simple to do.

actually very simple.
What happens when you open the data URL with a web browser ?
Does the connection stay open and automatically update each time there
is new data ?
If so, just use urllib, leave the connection open and do a read()
every so often to see if there is new data.
Good luck!

You don't have to create another opener if you only want to add
some handler. You can use `add_handler` method, e.g.:
opener.add_handler(urllib2.HTTPCookieProcessor(cj))

What about:
from subprocess import call
call('ulimit -v 1000 && ulimit -v && ls', shell=True)
