Python Basics: Building Systems With Classes (Quiz)

Unsure why isinstance(jack, Dog) returns False. jack is in the Bulldog class which is a subclass of Dog, so should return True?

It does return True, and that’s what the quiz question expects. Are you getting a different result when you run the code?

Running the code

bobo = JackRusselTerrier()

is throwing a syntax error

@Lilian Cipciriuc If you’re seeing a syntax error, then it must be caused by an earlier piece of code because the line that you posted appears to be synactically correct. The error’s stack trace should point you in the right direction, though, as it usually includes the offending line of code.

Here’s an example:

>>> def function
  File "<python-input-0>", line 1
    def function
                ^
SyntaxError: expected '('
