Customer mobile

Create a Customer class that uses accessor (getter) and mutator (setter) methods to control access to its properties.

---

1. Class Properties

• name
  • Should be immutable (cannot be changed after the object is created).
• phone_number
  • Should be mutable (can be changed after the object is created).

---

2. Class Methods

• __init__(self, name, phone_number)
  • The constructor that takes name and phone_number as parameters.
  • Initializes the object’s properties with these values.
• Accessor Methods (Getters)
  • get_name(self)
    • Returns the customer’s name.
  • get_phone_number(self)
    • Returns the customer’s phone number.
• Mutator Method (Setter)
  • set_phone_number(self, new_phone_number)
    • Takes a new phone number as a parameter.
    • Updates the customer’s phone number.
    • (Only this property can be changed; the name cannot be modified).

---

3. Task Instructions

1. Write the Customer class with the constructor and the three methods described above.
2. Create an object (instance) of the Customer class.
3. Test the class by:
   • Using the getter methods (get_name, get_phone_number) to retrieve the values.
   • Using the setter method (set_phone_number) to change the phone number.
   • Verifying that the phone number has been successfully updated.

class Customer:

    def __init__(self, name, phoneno):
        self.name = name
        self.phneno = phoneno

    def get_name(self):
        return self.name

    def get_phoneno(self):
        return self.phneno

    def set_phoneno(self, ph):
        self.phneno = ph


c1 = Customer('John', 7650984321)

print('Name:', c1.get_name())
print('Phone No:', c1.get_phoneno())

c1.set_phoneno(6789012345)

print('')
print('Name:', c1.get_name())
print('Phone No:', c1.get_phoneno())
