How to partition a list into n nearly equal parts in Python

Divide a list into n contiguous chunks of nearly equal size using an average-length calculation that distributes the remainder evenly.

    if n <= 0:
        raise ValueError("n must be positive")

    avg = len(lst) / n
    last_idx = 0.0
