[Tutor] a class knowing its self

[Shuying Wang]

Ben,

If you change example #b to:

for s in SkillNames:
   skill = Skill()
   skill.setName(s)
   print skill.getName()

You will find that the results are the same as #a. In your #b example,
you are giving setName() the skill instance instead of the string you
intended.
