while not

Question

Can anyone explain the use of this “while not” stuff??

Answer 1

while not X is simply making the loop go on and on when "not X" is true (implying that X is false then).

Answer 2

The way i remeber this is when somthing is false or vise versa use ! to make it the opposite value for example

boolean i = false;
boolean j = !i;

so..

i = false and j = true 😉

if somthing is not false then it can only be true.

Answer 3

//Edit:
"While not stuff" ????

Answer 4
