Now you'll focus on coding a salary setter. After the salary getter, create a simple setter for the salary property that sets self._salary to the value passed to the method as its argument. After that, print Salary updated to $ followed by the new salary and a period.

You'll take care of validating the new salary in the next few steps.

--hints--

Your Employee class should have a salary method decorated with @salary.setter.

({ test: () => assert(runPython(`_Node(_code).find_class("Employee").find_functions("salary")[1].has_decorators("salary.setter")`)) })

Your salary setter should set self._salary to the value passed to it as the argument.

({ test: () => runPython(`
  emp = Employee('Frank', 'trainee')
  built_in_print = print
  print = lambda x: x
  emp.salary += 100
  print = built_in_print
  assert emp.salary == Employee._base_salaries['trainee'] + 100
`) })

Your salary setter should print Salary updated to $ followed by the new salary and a period.

({ test: () => runPython(`
    import io
    import sys
        
    captured_output = io.StringIO()
    sys.stdout = captured_output
        
    emp = Employee('Frank', 'trainee')
    emp.salary += 100
        
    sys.stdout = sys.__stdout__
    output = captured_output.getvalue()
        
    assert f"Salary updated to \${Employee._base_salaries['trainee'] + 100}" in output
`) })
