Python 3.13 Changes _verified_ -

async def main_new_way(): # Python 3.13 - same syntax, but ~10-15% faster # Task creation and scheduling overhead reduced async with asyncio.TaskGroup() as tg: tasks = [tg.create_task(process_item(i)) for i in range(1000)] return [task.result() for task in tasks] async def benchmark(): start = time.perf_counter() await main_old_way() old_time = time.perf_counter() - start

# With cache (now faster decorator execution) start = time.perf_counter() result_cached = fibonacci_cached(n) cached_time = time.perf_counter() - start python 3.13 changes

print("\n✅ Code ready for Python 3.13") Performance Comparison Example import timeit import sys def performance_showcase(): """Compare 3.12 vs 3.13 performance""" async def main_new_way(): # Python 3

import asyncio import time async def process_item(item): await asyncio.sleep(0.001) # Simulated I/O return item * 2 python 3.13 changes
