Looked interesting, but way over my head, I gave it a try. I got the following errors and don't have a clue. I sent them to the feedparser author of possible help.
I'm still at the beginner level trying to get cute graphics and menus on the screen with TKinter. :)

Traceback (most recent call last):
File "C:\Users\Bo\Downloads\Adafruit_CircuitPython_MatrixKeypad-main\examples\RSS-Feed-Reader.py", line 3, in <module>

Thanks! Strangely the program had a comment to that change but failed to fix it!🤔
Fixing it in 2 files fixed it and it 'ran'
However the web page results has a list of new errors!
I'll list them but don't worry/bother if fixing it is a mess.
Again over my head but looked like one I could get going. 73. Bo

I traced down all the comments and it looks like the problem is with the https://rpilocator.com/feed error listed.
Headed there now. A 'RPI locator' will find about 6 of them here.😂

WAIT! How dumb I am. I actually have closer to 10 Pi's and need NO more.
I was thinking it could be easily modified to do for 'fun' /educational things.
I probably should quit this one.

Earlier I struck out just trying to scrape the solar data from https://www.hamqsl.com for a cute display.

I am succeeding in getting a Pi, tkinter,Python, arduino, stepper motor controlling a mag loop antenna.

Removed from v3.10


In the article the author uses Thonny 4.0.0.

Thonny 4.0.0 comes with Python 3.10.6 - this script would've NEVER worked without any error! o_O
