Answer 1

the reason why

print (bool("ab"))

results to True is:

▪︎a str is an iterable object (like list, set, dict). all iterable objects are considered to be True, if they are non-empty.

when using:

print (bool(""))

the result will be False

having that in consideration, we can use this to check if iterables are empty or not:

res = []
if res:
...

Answer 2

its a bool cause you used bool() and it's true because it has something.

Answer 3

I think it's because there is a value different from zero inside bool.
