I have no idea what most of that means in practice.
This looks very Arduino specific so you will probably get better results 
asking on an Arduino forum rather than a Python language list.
However...

This is a string of hex digits.
Do you mean to send the character representations of the hex or do you 
mean to send the actual hex digits?

You don't need the parentheses, they do nothing here.
But again this is a string representation of the hex data,
is that really what you want?

Posting images on a text based mailing list is not usually helpful.
If you can post the text of the message that is better.
