Python allows you to write a somewhat simpler if condition instead of
using "and":

if 0.8 < threshold <= 0.9:
    <your code block here>
etc.

Are you aware of Python's if - elif - else structure?  In your case it could be:

if 0.8 < threshold <= 0.9:
    <code block 1>
elif 0.4 < threshold <= 0.8:
    <code block 2>
elif 0.1 < threshold <= 0.4:
    <code block 3>
elif threshold <= 0.1:  # What about negative values of threshold?
    <code block 4>
else:
    <Throw an exception or something similar for all other possible values?>

I'll leave your other questions to someone else.

HAPPY NEW YEAR TO YOU AND YOURS!!!
