use evince (on Linux) to read PDF docs. When I open a document
the second time, evince automatically shows the last page I was
viewing when I previously closed evince. And, the following
command:
$ evince -p 12 somedocument.pdf
will open that document to page 12.
note the restriction to string values in
the docs on the set method:
set(section, option, value)
If the given section exists, set the given option to the specified
value; otherwise raise NoSectionError. While it is possible to use
RawConfigParser (or ConfigParser with raw parameters set to true)
for internal storage of non-string values, full functionality
(including interpolation and output to files) can only be achieved
using string values. New in version 1.6.

advance.
Try ljust and rjust. They are string functions/methods and are
described here: http://docs.python.org/lib/string-methods.html
Something like the following might work for you:
In [1]: value = 3.45678
In [2]: ("%0.3f" % value).rjust(10)
Out[2]: ' 3.457'
dit/commissioning function (still running my Python code as
a back end) and apparently I am due some kind of company reward ...
My thoughts on my first Python QT project ... would have been nice if I could
have given it to the community ... wonder what they will pay me ? ...

This would work but seems a bit messy. Any comments of suggestions on a better
solution ?
The data to & from the C++, Python code consists of fairly large tables of up

so much out there but it does seem
to be for remote apps.
SQLite ? - just Googled it and it looks interesting. Licence seems OK too -
these guys are allergic to the GPL - reportlab is BSD. That's another reason
that they want their own GUI - QT4 on windows
Thanks onc

The first call returns as expected, the second should return 99, 99
not 1, 99. On opening daemons.rc the 'number' option is not changed.
Any ideas ?

Then process *that* list.
then follow Andreas's suggestion to use list append
followed by string join.
