Extending a class

In the previous exercise, you defined an Employee class with two attributes and two methods that set those attributes. Remember, methods are functions, so anything you can do with a function, you can also do with a method.

For example, you can use methods to print or return values, or to make plots, as long as the behavior is appropriate for objects of that class, e.g., an Employee probably wouldn't have a pivot_table() method.

In this exercise, you'll learn how to use existing class attributes to define new methods. The Employee class and the emp object from the previous exercise are in your script.py.

Exercise instructions

  • Add a method give_raise() to the Employee class that increases the salary by the amount argument passed to give_raise().
  • Create the emp object.
  • Print the salary attribute of emp.
  • Call give_raise() on the emp object, increasing their salary by 1500.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

class Employee:
  def set_name(self, new_name):
    self.name = new_name

  def set_salary(self, new_salary):
    self.salary = new_salary 

  # Add a give_raise() method with amount as an argument
  ____ ____(____, ____):
    ____.____ = ____.____ + ____

# Create the emp object
emp = ____
emp.set_name('Korel Rossi')
emp.set_salary(50000)

# Print the salary
print(____.____)

# Give emp a raise of 1500
____.____(____)
print(emp.salary)
