While loop question, one too many loops happens.

I want the counter to stop counting once the value '1' is entered. If '1' is entered when running this script, the while loop runs once more before ending. I do not want this. Am I using break the wrong way, or is something else happening?
Thanks
counter=0;
y_n=0;
while y_n==0
if y_n==1
break
end
counter=counter+1
y_n= input('enter 1 or 0\n')
end

You just tested that y_n == 0 in the while statement. It cannot have changed value by the very next statement, at which point you test whether y_n==1 . You should move the "if" to after the input() .
Question: What do you want to have happen if the user enters (for example) 2.134473 ? That is not 0 so the while condition will no longer be true, but the if y_n==1 would be false.
