In what instance is the "not" operator to be used?

Specifically asking why would you want the inverse of a Boolean? What is it's practical purpose?

basic example : ● suppose you want to take print numbers in range 1 to 100 which are not divisible by 3, the condition you will be putting will be (n%3)!=0 OR !(n%3==0).

The simplest example: you need to check that one variable is NOT equal to another variable)

In cases of equality you rather would write != instead of not. But generally you can turn around every boolean with not not True -> False not x -> x == zero not arr -> arr is empty Things like that.
