So, is this a change from WIN10?
and is IDLE not affected by this change?
And what use is the following from MRAB:
I always find a script's location with `__file__`.
If "HLY-LOG5.txt" is in the same folder as the script, then its path is given
by:
from os.path import dirname, join
log_path = join(dirname(__file__), "HLY-LOG5.txt")
