Python 11.9 2021 May 2026

Below is a piece of Python code demonstrating a feature introduced or stable in , like Self type hint, ExceptionGroup , or tomllib . # demo_python_3.11_features.py # Compatible with Python 3.11.9 import tomllib from typing import Self

# ExceptionGroup demonstrate_exception_groups() python 11.9

class Temperature: def (self, celsius: float): self.celsius = celsius Below is a piece of Python code demonstrating

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 like Self type hint

try: fail_with_errors() except* ValueError as e: print(f"Caught ValueError: {e.exceptions}") except* TypeError as e: print(f"Caught TypeError: {e.exceptions}") except* ZeroDivisionError as e: print(f"Caught ZeroDivisionError: {e.exceptions}") if == " main ": print("=== Python 3.11.9 Demo ===")

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.
