Hello there! I'm new with Urwid and I'm trying to use it for a littel
project. I've been reading about it and doing simple snippets for 2 weeks.
At the moment I'm just making a proof of concept. I've modified the fib.py
example in order to use SimpleListWalkter with a list, called lalista, and
I'm trying to update the list every second.
When running the attached example, I expect to see the screen been filled
with the 'hola' string every second, but nothing happens.
What am I doing wrong?
Thanks in advance,
