Hi Swaroop,

I like A Byte of Python very much, I recommended it to python learners many times, last weekend one
of them(actually my girlfriend) told me why not use the "self.class" attribute instead of the
__class__ that I have taught her. Then I found the misunderstanding was from the ABP website
http://www.swaroopch.com/notes/python/ , for all the double underlined words have become italic. I
guess it's related to markdown somehow, because we have meet the exactly same problem, which kills
a lot of '*'.

Just remind you, in case you don't know the problem there, and a lot of learners will suffer, for
this book is so famous :)

best wishes,
Dan
