How do I chunk lists in Python with standard library only?

Chunking lists in Python is a common task that can be easily accomplished with the standard library. This method helps break down large lists into smaller, more manageable parts or "chunks". Below is a simple function that demonstrates how to achieve this using basic Python constructs.


def chunk_list(input_list, chunk_size):
    """Splits a list into chunks of specified size."""
    for i in range(0, len(input_list), chunk_size):
        yield input_list[i:i + chunk_size]

# Example Usage:
my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
chunked = list(chunk_list(my_list, 3))
print(chunked)  # Output: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
