Also, which python version do you use? This formatting method is supported in Python 3.6+ If you use 3.5 this way will not work and will throw something like this:

Error:
File "<ipython-input-49-81c34fb8cbaf>", line 14
    print(f"{item} €{self.menu[item]}")
                                     ^
SyntaxError: invalid syntax

And also the point that j.crater mentioned :)
