You mix booleans and numbers.  Furthermore you don't seem to fully
understand what `is' is for.

If you're not sure which type of equality you're interested in, use `=='
`is' tests for identity not only equality.  The best is you should read
in the Python reference about `is'.  There was also in clp a long
discussion about `is' and `=='.
