Hello, there.
MRAB, thank you for teaching me proper Python syntax for how I tried to
use the or operator.
Dennis, I must have learned allot recently as I believe I understood 99%
of that code. I see how it is not just more advanced, but actually better
than what I had. However, line 47
Hello.
Thanks to the help of people here and in other newsgroups I seem to have
something working doing the basics. (Buttons work, colours light up
appropriately.)
When I followed MRAB's instructions and read about scopes of variables
that solved my most recent problem, but it introduced

Thanks for replying. I got so hyper focused on solving my hardware
problems, and excited that I did, that I forgot details from previous
comments. Thanks for your post.
Off to make things global...

Hello.
As per the suggestion of two of you I went to the Raspberry Pi
newsgroup. Dennis is also there and has been posting in response to my
problems. Between there and the Raspberry Foundation website I discovered
that my wiring did not match my code and changed all PUD_DOWN to PUD_UP

Hakugin: Thanks for the correction. Someone elsewhere showed me example

I am not familiar with the module, but I am quite familiar with dealing
with hardware interfacing, mostly in assembler.
