Note on the Suggested Solution¶
The normalize…
-methods do not need neccessarily need to be member methods,
since they do not use the self
reference in any way.
It is done this way because we have not learned about static methods yet.
An alternative solution would be to assign the values in the __init__
first.
Then call the normalize…
-methods with only the self
parameter, and use side
effects to correct the values.
