The main thing is to write a lot of code, so think of a
project and build it. The experience
Alan,
Yes, 2.7 here. I wanted to use 3, but the API only supports 2.7.
And, I'm not about to get into rewriting an API. :)
So, octets it is. Thank you for the clarification.
Yes, my background is C, let me look into your suggested method.
It is the shifting across those byte boundaries that i

Because you want to convert the byte array into an int.
And there is no long in Python...
Really? :)

Being slightly picky but an octet and a byte are subtly different.
An octet is a group of 8 bits with no meaning attached.

Peter,
Thank you for taking the time to create the example.
I'm new to Python, and, as a result, about a quarter of your example
makes sense to me. The remainder I will have to start googling to see
if I can get my head around it.

Hopefully this will clarify things. Again, not knowing how much
information is too much... I know I can be too verbose and that's not
always a good thing.
I have a bank of registers that I read via SPI. The SPI API is from
the IC manufacturer.

Alan,
Thank you.
Another related question. How do I know I want to do dir(int) vs.. I

And, when I do dir(int) I get the following results. I must not be

Mats,
Thanks for the suggestion.
Even if I did mask, I would still have to shift the data to line it up
properly. And the shifting seems to be where I'm introducing my
error(s).
This bit stream is complicated in that I have to reverse the bytes as
well since I'm reading off the 'end' of a bunch
First,
Steven,
Thank you for your insight.
