[Tutor] errors in "Python Programming for the Absolute Beginner"??

[Bill Allen]

Vern,

Quite right!   I see what you mean.  I quite inadvertently stumbled into
examples that would work without realizing it.   I typically program in
Python 3, so not as familiar with the limitations on Python 2x.   I've had
quite a chuckle over this!

Thanks,
Bill
