That value will either behave exactly the same as the Boolean value
you call correct, or else it will be more useful. That is, most of the
time it doesn't matter, and when it matters, Python's way is better.

You can turn any expression E into a strictly Boolean value by writing
bool(E) instead. Often E is already guaranteed to be a Boolean and the
whole question does not arise in the first place.

This doesn't prevent you from writing your program.
