The main thing is to write a lot of code, so think of a
project and build it. The
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

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.
So an

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
don't know dir(long)?
And, when I do dir(int) I get the following results. I must not be
seeing the from_bytes in this list...

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
First,
Steven,
Thank you for your insight.

You have posted code sprinkled with prints and irrelevant details.
