Did you mean this?

if thisCalculator in calculators:
        raise CircularDependency(thisCalculator)

Or maybe this?

if thisCalculator not in calculators:
   # put the unsafe code here
else:
   # alternate behavior for the special case here

(unless the condition is really rare so that it makes sense to treat it as an 
error).

Cheers,
Terry
