How do I paginate dicts in Python safely and idiomatically?

When working with large dictionaries in Python, it's important to paginate the data to improve readability and usability. This can be achieved safely and idiomatically by utilizing generator-based approaches or by slicing the dictionary into smaller segments. Below is an example illustrating how to implement pagination for dictionaries.

def paginate_dict(data_dict, page_size): """Yield successive pages from a dictionary.""" keys = list(data_dict.keys()) for i in range(0, len(keys), page_size): yield {k: data_dict[k] for k in keys[i:i + page_size]} # Example usage data = { 'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5, 'f': 6, 'g': 7, 'h': 8 } # Paginate the data dictionary with page size of 3 for page in paginate_dict(data, 3): print(page)
