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).

Answer 3

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

Answer 4

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.
