Is there a pythonic way to add a text description to instance objects?

Question

I think it is best to explain what I want by giving the way I'm currently doing it:

class Car:
    def __init__(self, vehicle):
        self.vehicle = vehicle

    def set_driver_temperament(self, text):
        self._driver_temperament = text

    def get_driver_temperament(self):
        return self._driver_temperament


driver1 = Car('Toyota Camry')
# A lot of code here
driver1.set_driver_temperament("""
        Cool Headed
        Financial Wise""")

driver2 = Car('Ferrari')
# A lot of code here
driver2.set_driver_temperament("""
        A**hole
        Too much money, too little brains""")

I just want to know if there is a more pythonic way of doing this? I checked online, but I cannot find anything

Edit:

So the example is not too clear, but the driver_temperament can not be set at the initial declaration.
