Re: [pyusb-users] Significance of 'B' Character in Data Arrays
Jared,
You were close, 8.6 of the docs is what you were looking for.
See https://docs.python.org/2/library/array.html for full description of the
python array standard library module.
If you don't have a need to run python 2.7, I suggest using Python 3 it copes
with bytes and strings more explicitly. Working with low level stuff i fond it
more useful than coercing python 2 to work properly with bytes and strings
(unicode)
Especially when I use utf-8 in my programs.

[pyusb-users] Significance of 'B' Character in Data Arrays
Hello!
I've managed to read data! At this point, I need to decipher it. I wanted
to confirm my suspicion that the B in the following array:
array('B', [3, 4, 2, 0, 22, 0])
Signifies that an unsigned char is being received from the backend library,
similar to what is seen in the table section 7.3.2.2 at
https://docs.python.org/2/library/struct.html
Is this the case?
Thanks in advance!
Best,
Jared
