Answer:
class Phone(object):
    def __init__(self, model, partNumber, retailPrice):
        self.model = model
        self.part_number = partNumber
        self.retail_price = retailPrice
 
    def phone_specs(self):
        print( "Phone model: {}\nPart number: {}\nRetail price: {}".format( self.model, self.part_number, self.retail_price))
phone1 = Phone("Nokia", "asd234", 200.0)
phone1.phone_specs()
Explanation:
A class is a blueprint of a data structure used to create objects of the same data types and methods. The Phone class is an object that creates an instance of the phone1 object. The phone_specs method is used to display the details of the phone1 object.
