Python "while X:" Statement

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 some

Solution 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.

Solution 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
