Why does my code run fine in workspaces but I get a SyntaxError on VS Code?

class Car:
    wheels = 4
    doors = 2
    engine = True

    def __init__(self, make, model, year=2021):
        self.make = make
        self.model = model
        self.year = year
    def stop(self):
        print("The car has stopoped")
    def go(self, speed):
        print(f'The car is going {speed}')

car_one = Car("Ford", "Model T")
car_two = Car("Model X", 2021)
car_one.stop()
car_one.go('fast')

ROBERTOs-MBP:~ roberto$ python -u "/Users/roberto/Downloads/cars.py" File "/Users/roberto/Downloads/cars.py", line 13 print(f'The car is going {speed}') ^ SyntaxError: invalid syntax

Hi Roberto,

In workspaces python references some (the latest???) version of Python 3 (Python 3 is when f strings were introduced into the language).

I imagine that in VS Code/on your local machine, python references Python 2. Assuming you have already installed Python 3 onto your machine, try the following in your terminal. 

ROBERTOs-MBP:~ roberto$ python3 -u "/Users/roberto/Downloads/cars.py"

If you haven’t installed Python 3 yet, you’ll need to do that first.

Hopefully, that’s work out for you. Good luck.
