Are you sure you have the write permission for the Shape FILE ? Type
"ls -l" to have a look.

Chintan,
your code works perfectly here...no error.. I am on Windows XP.
however, it only deletes the .shp file, not all the files that comes
along! ... you might want to look for all files that start with your
filename, no matter of the extension, and then delete them
