ValueError: invalid literal for int() with base 10:

i don't understand why b is a problem, it works fine with +
Look at the error message. Carefully! It says, quite clearly, the call
to int is being passed a string "Adafruit-Raspberry-Pi-Python-Code",
which of course can't be converted to an integer.
Now the question is how you ran the program in such a manner that
sys.argv[3] has such an odd value.
What does your command line look like? You didn't tell us, but that's
where the trouble is.
