How do I chunk dicts in Python for production systems?

Chunking dictionaries in Python is essential for production systems where efficiency and performance are critical. This technique involves breaking down a large dictionary into smaller, manageable chunks for processing. Below is an example that demonstrates how to perform this operation effectively.

def chunk_dict(d, chunk_size): """Yield successive chunks from a dictionary.""" it = iter(d) while True: chunk = dict(itertools.islice(it, chunk_size)) if not chunk: break yield chunk # Example usage large_dict = {i: i * 2 for i in range(1, 10001)} # A large dictionary for chunk in chunk_dict(large_dict, 1000): print(chunk) # Process each chunk
