PyLint does not like me.
Done.
Hi,
I have read your comments and I have a question.
if a and b: print("True")
will be True if a is positive and b is negative or vice versa. This would introduce a bug if for some reason one of them is negative and you really want to check for both > 0. This is why I explicitly check for > 0. I can drop the parentheses and everything will still come still be right.
What do you think?

Thanks for submitting this. I've made some suggested changes that should help with it passing linting. I'm not sure why you changed it to import from matrix which imports from the base class (ht16k33) rather than just importing the ht16k33 class for better memory usage.

Why was this changed from the base class to the 8x8 matrix class?

I'd suggest removing the debug statements. They're long and make the library larger. They also seem to be the source of a lot of the linting problems.

This docstring should be moved into the correct function.

Ok yeah, that makes sense. If pylint fails on that, you can add lines to disable certain checks with #pylint: disable-msg=[pylint-fail-code]
and replace [pylint-fail-code]
with the actual fail code.
Done! I will get better as I learn what PyLint expects.
This is a port of the changes I did to the number() routine in the micropython version of this library. I also found several errors in processing floats and negative numbers, which I fixed. This version is much more robust. I also fixed a problem with the "from adafruit_ht16k33 import..." line.
