Python “while x:” statement [duplicate]

Why the following while loop is exited when x reaches 0?

x = 1
while x:
    print(x)
    x -= 1

It prints only 1. Shouldn't the while statement be something like: while x "is something": and not just while x:?

Answer 1

Because bool(0) => False, and bool(x) for x!=0 => True, so it's like saying while x!=0 or while x>0 in your case.

Answer 2

In boolean, none zero value means 'true' and 0 means 'false'. The code reaches the argument while(0) or while(false) and terminate the body
