Build a Salary Tracker - Step 39

Python
1

Tell us what’s happening:

I inserted the following snippet which passes the test:
if hasattr(self, ‘_level’) and new_salary < self._base_salaries[self.level]:
raise ValueError(f"Salary must be higher than minimum salary ${Employee._base_salaries[self.level]}.")

However I get an error: Your if statement should use hasattr(self, ‘_level’) to check if _level exists before comparing.

this error is nonsense since I obviously included hasattr(self, 'level')

Your code so far

class Employee:
    _base_salaries = {
        'trainee': 1000,
        'junior': 2000,
        'mid-level': 3000,
        'senior': 4000,
    }

    def __init__(self, name, level):
        self.name = name
        self.level = level
        self.salary = Employee._base_salaries[level]

    def __str__(self):
        return f'{self.name}: {self.level}'

    def __repr__(self):
        return f"Employee('{self.name}', '{self.level}')"

    @property
    def name(self):
        return self._name

    @name.setter
    def name(self, new_name):
        if not isinstance(new_name, str):
            raise TypeError("'name' must be a string.")
        self._name = new_name
        print(f"'name' updated to '{self.name}'.")

    @property
    def level(self):
        return self._level

    @level.setter
    def level(self, new_level):
        if not isinstance(new_level, str):
            raise TypeError("'level' must be a string.")
        if new_level not in Employee._base_salaries:
            raise ValueError(f"Invalid value '{new_level}' for 'level' attribute.")
        if hasattr(self, '_level') and new_level == self.level:
            raise ValueError(f"'{self.level}' is already the selected level.")
        if hasattr(self, '_level') and Employee._base_salaries[new_level] < Employee._base_salaries[self.level]:
            raise ValueError("Cannot change to lower level.")
        print(f"'{self.name}' promoted to '{new_level}'.")
        self.salary = Employee._base_salaries[new_level]
        self._level = new_level

    @property
    def salary(self):
        return self._salary

    @salary.setter
    def salary(self, new_salary):
        if not isinstance(new_salary, (int, float)):
            raise TypeError("'salary' must be a number.")

Hi @dwo,

Sometimes error messages don’t point to the exact issue.

But notice you’re writing self._base_salaries[self.level] in your if condition and Employee._base_salaries[self.level] in the message.

Happy coding!

Your if statement should use hasattr(self, '_level') to check if _level exists before comparing. i am getting this message
