Get and Set
Getter and setter are methods for non-direct access to the attributes:
get()(getter) returns the value of the private attribute;set()(setter) sets the value.
These methods are called properties.
You can implement them by defining two additional methods:
12345678910111213141516171819202122class Cat: def __init__(self, name = 'Kitty', age = 1): self.name = name self.__age = age self.__children = 0 # Getter def get_age(self): return self.__age # Setter def set_age(self, age): if isinstance(age, int) and 0 <= age <= 30: self.__age = age else: print('Invalid value of attribute age') cat = Cat('Maggie', 3) # Wrong value cat.set_age(-23) cat.set_age(8) print(cat.get_age())
Note
We added data validation inside the set_age() method. Only the correct integer value can be assigned to the attribute.
