The format strings are described here for Python 3:
http://docs.python.org/3.2/library/struct.html
and here for Python 2:
http://docs.python.org/2.7/library/struct.html
I used this documents but they do not explain or provide an example on how to
use struct.unpack for sensor data from an external source or even data from a
excel sheet.
If you want to read from an Excel file you should be using the 'xlrd'
module. You can find it here: http://www.python-excel.org/
