Python Object-Oriented Python Advanced Objects Dream Car

In the method, return a string that states the dream car's make and model

I cannot get this one,

dream_car.py
class DreamCar:
    def __init__(self, make, model):
        self.make = make
        self.model = model
    # insert your code here
    def __str__(self):
       return"My car {} {}".format(self.make, self.model)

The instructions ask for output that looks like "My dream car is a {make} {model}.", but this code would output a string like "My car {make} {model}" instead.

But I wasn't able to get it to work even with a corrected string. It seems like there might be a bug in challenge's handling of the "format" function. If you have the same issue, you might want to submit a bug report as described on the Support page (you might get an "Exterminator" :beetle: badge!)

But I was able to make it pass using "f-string" formatting:

        return f"My dream car is a {self.make} {self.model}."

Manuel,

This should work.

class DreamCar:
    def __init__(self, make, model):
        self.make = make
        self.model = model
    # insert your code here
    def __str__(self):
        return f'My dream car is a {self.make} {self.model}.'

Thanks Steven

I am stock, the program sitll ask function should only take self argument?

class DreamCar: def init(self, make, model): self.make = make self.model = model # insert your code here def str(self, make, model): return "My dream car is a {} {}".format(self.make, self.model)

File "", line 40, in test_function_code AssertionError: 1 != 3 : Your function should only take the self argument
