[BangPypers] help to understand this code

[T S KAMATH]

My Apologies for yesterdays post.. It was click "send" instead of "draft"..  Moderator pls "del" the earlier post.

I am no developer nor a hardcore programer. I just use open Source to find "work around" to issues and or to automate. all my stuff is open source and free to use. Hence pls excuse if some of my post.. 

I shall send my correct post.. with the correct heading.. Thanks in advance
