Greetings, i'm a total amateur using py 2.5 on Win XP...
I posted a similar message last week and I made the suggestion, yet I'm ending up with the same problem...
In my script after I ask it to print i get "None" WHY is that, what can I do to fix it?
here's my script -
>>> import urllib2, sched, time, re
-
>>> def debtcheck():
-
... webpage = urllib2.urlopen('http://www.brillig.com/debt_clock/')
-
... results = webpage.read()
-
... total_debt = re.compile('<TR><TD ALIGN=center><IMG SRC="debtiv.gif" WIDTH=399 HEIGHT=41 ALT=(.*?)</TD>',re.M|re.DOTALL)
-
... debt_data = total_debt.findall(results)
-
... return debt_data
-
...
-
>>> s=sched.scheduler(time.time, time.sleep)
-
>>> def print_debt():
-
... s.enter(5, 1, debtcheck, ())
-
... s.enter(35, 1, debtcheck, ())
-
... s.enter(65, 1, debtcheck, ())
-
... s.run()
-
...
-
>>> print print_debt()
-
None

It is because you didn't return anything from print_debt(). Instead of return debt_data in debtcheck you can put print debt_data or store it in a file, whichever is more convenient for you. There might be a better way though because I'm not that into the sched module.

Hi,
I have a little problem with encoding. Was hoping maybe anyone can
help me to solve it.
There is some amount of data in a database (PG) that must be inserted
into Excel sheet and emailed. Nothing special, everything works.
Except that non-ascii characters are not displayed properly.
The data is stored as XML into a text field. When I use pgsql it's
displayed good in the terminal. Now I run my script and print data
