And to further enhance Alan's point, this eliminates floats presented as
strings when you really only want integers and not floats:

3.8.3:  int("1.0")
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   ValueError: invalid literal for int() with base 10: '1.0'

If I recall correctly when I first discovered the Tutor list I asked the
question why "int('1.0')" did *not* convert it to the integer "1", but
instead threw an exception.  It occurs now to me how useful the Python
design has proved to be for me!
