The statement "if break is False:" is wrong.

Your variable is called "breakout" not "break". In fact, you cannot have 
"break" as variable, the above code will not be accepted by the Python 

There are also a few improvements possible:

You want to use "==" for comparing values. The "is" that you use compares 
objects rather than values.

Also, comparing boolean values with True or False in a condition is not 
needed, you can use the boolean value directly. In this case "not breakout" 
will give you the same result.
