Tested and known to work.

You seem to be doing well with Python, nice job on the dictionary usage. Just a reminder incase you don't already know, the following line

print 'verbyte: %s' %(verbyte)
can also be written as

Code Select Expand

print 'verbyte: %s' % verbyte
When you are only inputting a single variable when formatting text, you don't need to enclose that variable with parenthesis, you only need to enclose it when there are 2 or more. IMO, no parenthesis when one variable is used looks nicer, you may think otherwise.
