    Some one asked about speed of handling exceptions in Python.

    Response:
    First one codes for clarity, not speed.
    Until one measures that speed is too slow, don't worry about speed.

        "Premature optimization is the root of all evil."

    That said, handling exceptions is something that Python does well and fast.
    Exceptions are pervasive in Python, much more than many people realize.
    For example, iterators are terminated by a StopInteration exception. 
    https://docs.python.org/3/library/exceptions.html#exceptions.StopIteration
    http://anandology.com/python-practice-book/iterators.html#the-iteration-protocol
    
    That person volunteered to make 1.5 million strings to test
    LBYL v EAFP speed in safe_float(). Watch the mailing list for updates.
