Thanks David, it solved my problem immediately. 

I will follow your advise from next time but honestly I am new to python
with not much knowledge about text formats. And the main portion of my
project was not to deal with these, so I just wanted to get this solved as I
was already struck at this for 2 days. If you think I am wrong in my
approach to getting problems solved, please let me know. Your advise would
be helpful in future for me.

--Thanks Again,
