1. Subclass Method __init__ ()
When a class inherits another class, he automatically obtains all the properties and methods of the other class. The original class is called the parent class, and the new class is called a subclass. A subclass inherits all the properties and methods of its parent class, and can also define its own properties and methods.
When you create a subclass, the parent class must be contained in the current file and in front of the subclass
When you define a subclass, you m
the maximum number of values in the above equation has the greatest impact on the results, meaning that the number of frequent flyer miles earned per year will have a much greater impact on the results than the other two features in table 2-3-playing video games and weekly consumption of ice flooding litres. The only reason for this is the fact that frequent flyer mileage is much larger than other eigenvalues. But Helen believes that these three char

different features are not the same. Example: Sample features include height, weight, and mileage. The number of miles in the flight range is very high relative to height and weight. When calculating the distance between samples, the difference in mileage will be decisive, and it is generally assumed that all features should be equally important and that the values should be normalized to between 0 and 1:V
