How do I chunk dicts in Python safely and idiomatically?

In Python, chunking dictionaries can be done safely and idiomatically using list comprehensions and the `dict` constructor. This method allows you to divide a large dictionary into smaller, more manageable pieces, enabling better readability and processing.

Here’s an example of how you can chunk a dictionary into smaller dictionaries with a specified chunk size:

def chunk_dict(d, chunk_size): """Chunk a dictionary into smaller dictionaries.""" it = iter(d) for i in range(0, len(d), chunk_size): yield dict(list(zip(list(it), list(it)))[i:i + chunk_size]) # Example usage original_dict = {i: i * i for i in range(20)} chunks = list(chunk_dict(original_dict, 5)) print(chunks)
