[docs] [issue14306] try/except block is both efficient and expensive?

[Ezio Melotti]

Ezio Melotti <ezio.melotti at gmail.com> added the comment:

What it's trying to say is that in case the operation in the "try" block succeeds there's almost no overhead, so it's very efficient.  On the other hand, raising and then catching the error is expensive.
