So I'm trying to just write a script that checks to see the national debt every minute for 3 minutes. (the time and duration is completely variable, im making up these tests for me to learn on)...
So the script I have, which I've written by cutting and pasting from previous questions i've had answered and from what i've found on python.org, yields "None," rather than 3 gigantic debt figures.
Can someone help me (i'm using Windows XP on python 2.5) find where I've gone arwy...
thanks a lot...

None
first look, you did not return any values in your debtcheck() function that's why you have None.. return debt_data in that function, and i think it should be fine.

I have a page here that validates as XHTML 1.0 strict that works fine in

outside, making it nearly illegible. (Also, the page background color

Hi,
I was playing around with a tool available from gotdotnet to create
documentation from xml comment in vb.net. Part of what I had to do was
install an add in to allow help projects to be compiled.
Well, this add in, when used with a project, did something that messed up
the .NET help collection. Immediately afterwards, there was no index
available, and search was gone.

hi,
wrote the following program to learn a bit about auto pointers.
weird thing is, the char array 'name' with size 'max_size' displays a

Hi again
I am trying to import from an excel spreadsheet into access 2002, but the
order that is in the spreadsheet is not preserved when I import. using
DoCmd.TransferSpreadsheet in code.
Access sets indexes on certain fields with "Code" in the field. Even if I
remove these index, the order is close, but still some of the fields are out
of order.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
