Hello.
Very new to Python and looking for some basic help.
Would like a set-up where something happens when a key is pressed. Not
propose a question, have the user type something, then hit return, then
something happens, but just the R key is pressed, something happens, then
something else happens if the B key is pressed, then a third thing
happens if the G key is pressed.
My research only served to confuse me. Firstly, I do not understand how
it is possible for this to be a difficult thing not built into the system
for any scripting language made within the last few decades. More to the
point I am unclear on specific suggestions. Most of them seem to be for
Windows only and I want this working on a Raspberry Pi. Saw getch but I
am still confused if it is platform specific or not, or requires a module
to be installed or not. Just get errors if I try to install getch using
PIP.
Other suggestions seemed to be overkill and confused me to due to my
beginner level knowledge and the fact these suggestions have other, more
complicated elements to them.
I just want a button press on a device connected to a Raspberry Pi to
trigger an action. If anyone can give me some guidance on this I would
appreciate it.
Thank you.
