(a) Write a program to define a class Item with instance attributes name and price. Use assert to ensure that the user inputs a string for name and an integer for price. Also instantiate the class by using a suitable variable name. [4 marks] (b) Write a python class Employee. Create an _-init_- method to add attributes name and salary to the class. Create another method displayEmployee that prints the details of an instance. For instance: Name :Zara,Salary: 2000

### (a) Defining the `Item` Class with Assertions Below is a Python program that defines a class `Item` with instance attributes `name` and `price`. The `__init__` method uses `assert` statements to ensure that `name` is a string and `price` is an integer. The class is then instantiated using the variable name `item1`. ```python class Item: def __init__(self, name, price): # Ensure that name is a string assert isinstance(name, str), "Name must be a string" # Ensure that price is an integer assert isinstance(price, int), "Price must be an integer" self.name = name self.price = price # Example instantiation try: item1 = Item("Notebook", 50) print(f"Item created: Name = {item1.name}, Price = {item1.price}") except AssertionError as e: print(e) ``` **Explanation:** 1. **Class Definition:** - The `Item` class has an `__init__` method that initializes the `name` and `price` attributes. 2. **Assertions:** - `assert isinstance(name, str)`: Checks if `name` is a string. - `assert isinstance(price, int)`: Checks if `price` is an integer. - If the assertions fail, an `AssertionError` with the specified message is raised. 3. **Instantiation:** - The class is instantiated with `item1 = Item("Notebook", 50)`. - A `try-except` block is used to catch any assertion errors and display appropriate messages. **Output:** ``` Item created: Name = Notebook, Price = 50 ``` --- ### (b) Defining the `Employee` Class with `displayEmployee` Method Below is a Python class `Employee` with an `__init__` method to add `name` and `salary` attributes, and a `displayEmployee` method to print the employee's details. ```python class Employee: def __init__(self, name, salary): self.name = name self.salary = salary def displayEmployee(self): print(f"Name: {self.name}, Salary: {self.salary}") # Example usage emp1 = Employee("Zara", 2000) emp1.displayEmployee() ``` **Explanation:** 1. **Class Definition:** - The `Employee` class has an `__init__` method that initializes the `name` and `salary` attributes. 2. **`displayEmployee` Method:** - This method prints the employee's `name` and `salary` in the specified format. 3. **Instantiation and Method Call:** - An instance `emp1` is created with the name `"Zara"` and salary `2000`. - `emp1.displayEmployee()` is called to display Zara's details. **Output:** ``` Name: Zara, Salary: 2000 ``` --- These implementations ensure that the classes are correctly defined with the necessary attributes and methods, and include proper type checking and output formatting as specified.
