46: pi@raspberrypi ~ $Notice in Listing 17.12 that an additional exception has been added to the try except statement
block for the Python input statements in lines 25 through 29. This additional exception has been
added for catching keyboard interrupts, such as the user pressing Ctrl+C during data input.
Did You Know: Exception Groups
Exceptions belong to named exception groups. These exception group names can be
used in the except statement. For example, both ZeroDivisionError and
FloatingPointError exceptions belong to the ArithmeticError base
group. An except statement block could use ArithmeticError as its named
exception, like this:
except ArithmeticError:
