5,849 PointsCode works in workspaces. Why am I getting this error in the challenge task?
When I run this code in workspaces, it compiles fine and I get the desired output. When I run the same code in the challenge task, I get the following error:
FAIL: test_function_code (main.TestFunctionDefinitionCode)
Traceback (most recent call last):
File "", line 43, in test_function_code
AssertionError: Regex didn't match: '(\{self.make\})\s(\{self.model\})' not found in 'class DreamCar:\n\tdef init(self, make, model):\n\t\tself.make = make\n\t\tself.model = model\n\t\t\n\tdef str(self):\n\t\treturn "My dream car is a {} {}.".format(self.make, self.model)' : You'll need to use self
when using the attributes make and model.
Why is this?
class DreamCar:
def __init__(self, make, model):
self.make = make
self.model = model
def __str__(self):
return "My dream car is a {} {}.".format(self.make, self.model)

8,970 PointsI had the same problem, it is something in the code interrupter that doesn't let it work. Instead you have to use an 'f-string'.
def __str__(self):
return f"My dream car is a {self.make} {self.model}."
