getters and setters in python

class Person:
	# Constructor
	def __init__(self, name, age):
    	# Since we making getters and setters, we should mangle the varible names to make them "private" by adding 2 underscores.
    	self.__name = name
        self.__age = age
    
    # Getters
	def get_name(self):
    	return __self.name
	
    def get_age(self):
    	return __self.age
    
    # Setters
    def set_name(self, new_name):
    	self.__name = new_name
    
    def set_age(self, new_age):
    	self.__age = new_age

python should i use getters and setters

class Protective(object):
    """protected property demo"""
    #
    def __init__(self, start_protected_value=0):
        self.protected_value = start_protected_value
    # 
    @property
    def protected_value(self):
        return self._protected_value
    #
    @protected_value.setter
    def protected_value(self, value):
        if value != int(value):
            raise TypeError("protected_value must be an integer")
        if 0 <= value <= 100:
            self._protected_value = int(value)
        else:
            raise ValueError("protected_value must be " +
                             "between 0 and 100 inclusive")
    #
    @protected_value.deleter
    def protected_value(self):
        raise AttributeError("do not delete, protected_value can be set to 0")
