Just noticed this -
target_dir("D:\\backup") + "Zipnametoreplacestrftimeformatstring"+ '.zip'
= D:\\backupZipnametoreplacestrftimeformatstring.zip
No wonder it doesn't work.
Try

Hi Rankumar -
That's your problem then -
if os.system(zip_command) == 0:

So, os.system() returns 0 for Win 95,98, ME.
For XP, it returns whatever the exit code your programme returns .
So whatever zip returns, is what os.system() returns, which m
Have you looked at the ConfigParser module that was mentioned earlier
today?
Your file fits its format exactly...
But regular expressions can be used, try the intro in my tutorial,
or the excellent HowTo on the Python web site...

to convert it into a binary executable that can be
used to play it in Linux without needing the various

That rooted out the problem. A while ago, I changed the colors to kind
of match my VIM color theme(ps_color). When I did
idlelib.PyShell.main(), IDLE came up with my custom color theme.
However, there was a bunch of warnings about my theme. From IDLE, I

Has anyone ever worked this option?

If you want to be able to access the objects by name, you can put them in a
dict. For example,
MyObjects={}
l=["a","b","c"]
for i in l:
MyObjects[i] = MyClass(i)
Then you can refer to MyObjects["a"]
If all the operations on the objects are done to all objects in a batch, putting them in a

I'm sorry for this appallingly dumb question, but I'm having a little

I've written a class, with some methods. I then want to be able to call
