Lec 7 Visibility

• Python doesn't block visibility at all
  • Reliant on unenforced guidelines
  • vars beginning w/ _ can be accessed, but it's discouraged
  • vars beginning w/ __ can ONLY be accessed by doing _className__varName
• Something marked with the @property vector:
  • An attribute that's re-calculated each time it's accessed
  • Marks a method
  • If you create an "attribute" using the @property method, you can make a setter using @age.setter

class Person
    def __init__(self, first_name, last_name):
        self._first_name = first_name
        self._last_name = last_name
        self._age = age

    @property
    def name(self)
        return f'{self._first_name} + {self._last_name}
    @property
    def age(self):
        return self._age

    @age.setter
    def age(self, new_age)
        self._age = new_age

mini: Person = Person("mini", "bacon")
print(mini.name)
