Looks like you forgot a colon after the "C". Also note that C:\\Python26 is 
a bad place to store your own stuff.

A general remark on your code: it looks like you spend quite some time on 
it, and the up-front time it takes to make it reader-friendly will save you 
and others a multiple in debugging cost. So please

- Use 4-space indents
- Choose descriptive names, not a, t, f, that even if understood in the 
context of an expression will be forgotten three lines below. Also 'wrksht' 
or 'wrkSht' have no advantage over 'worksheet'. Vowels are your friend ;)
- Cut dead wood. Remove variables or imports that aren't currently used. You 
can always reintroduce them later on.
- Bonus: split your code into functions. It may seem like extra work at 
first, but it makes it easy to test small chunks of simple code and then to 
build more complex scripts by combining these "known good" pieces.
