[Tutor] time taken to execute certain task

[ALAN GAULD]

Profiling is really intended to profile a complex set of operations 
not a single statement, for that timeit() would be a better choice.

However in this case, it may be that the time is so low it simply 
doesn't register. Have you already imported math for example? 
In which case you are effectively profiling a single if statement...
