Python 11.9 <High-Quality>

class Temperature: def (self, celsius: float): self.celsius = celsius

@classmethod def from_fahrenheit(cls, fahrenheit: float) -> Self: celsius_val = (fahrenheit - 32) * 5/9 return cls(celsius_val)

If you meant from a known book (e.g., Python Crash Course or Think Python ), just let me know the problem statement, and I’ll give the exact solution.

It sounds like you're asking for a Python script related to version or a task numbered 11.9 (perhaps from a textbook or exercise).

Since “python 11.9” isn't a standard Python release, I’ll assume you mean (a specific micro version) or exercise 11.9 from a learning resource.

def to_fahrenheit(self) -> Self: """Return a new Temperature object converted to Fahrenheit scale.""" fahrenheit_val = (self.celsius * 9/5) + 32 # Using Self as return type (Python 3.11+) return Temperature((fahrenheit_val - 32) * 5/9) # Just for demo, normally store in F
