Understanding the Underscore( _) in Python

Very good article. Just to mention that Python does support getters and setters via the @property decorator. Instead of doing p._age to access the private attribute, you must add inside the Person class:

  @property
  def age(self):
      return self._age

  @age.setter 
  def age(self, value):
      self._age = value

Then access the value of _age with p.age
