Good start on this sprint's tasks, I have spotted a few areas where you could improve code further

| return number * 3 | ||

| print(double_bug(10)) # Should return 20 but returns 30 No newline at end of file |

can you think of any change you could make to this function to fix the bug?

Change number * 3 to number * 2 so the function doubles the input.

| return person.address # Error: Person has no attribute 'address' |

Could you suggest a change that would fix this error?

Add an address parameter to the Person class init and stored it as self.address
| self.DoB = DoB | ||
| self.preferred_operating_system = preferred_operating_system | ||

What is a benefit or drawback of writing the function this way?

Stores DoB (fixed), not age (changes over time), so is_adult() stays correct.
Rtores DoB (fixed), not age (changes over time), so is_adult() stays correct.

| @dataclass(frozen=True) | ||
| class Person: | ||
| name: str | ||
| age: int |

Can you solve this in a way that it always prints the current age, rather than hard-coding a specific age?
