How do I chunk lists in Python in an async application?

In an async application, properly chunking lists can aid in efficient processing and handling of large data sets without blocking the event loop. Below is an example of how to chunk a list in Python while maintaining compatibility with async operations:

def chunk_list(lst, chunk_size): """Yield successive chunks from lst.""" for i in range(0, len(lst), chunk_size): yield lst[i:i + chunk_size] # Example usage async def process_chunks(lst): for chunk in chunk_list(lst, 2): await async_process(chunk) async def async_process(chunk): # Simulate an async operation await asyncio.sleep(1) print(chunk) # Example list my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9] await process_chunks(my_list)
