Lab: Writing Classes

This lab will help you write classes.

Part 1: Write Classes

1. Empty Class

Write a class called my_class with no functions.

2. Instance

Make an instance of my_class called inst.

3. Write a Counting Class

Write a class called Counter. The class should have the following member variables:

• count: an integer

The class should have the following member functions:

• __init__ - Set the class variable count to zero.

  • Arguments:

    • self: The class instance

  • Returns: None

• plus_one - Add one to the count

  • Arguments:

    • self: The class instance

  • Returns: None

• minus_one - Subtract one from the count

  • Arguments:

    • self: The class instance

  • Returns: None

• print_count - Print the current count value.

  • Arguments:

    • self: The class instance

  • Returns: None

Test your class by creating an instance of it and using all member functions.

4. Update your Counting Class

Update the Counter class to have an __init__ function that takes an argument:

• __init__ - Set the class variable count to initial_count

  • Arguments:

    • self: The class instance.

    • initial_count: The initial value of the count variable.

Test your class by creating an instance of it and using both member functions.
