expand-and-setitem

A small utility function that expands a deque as needed and sets an item at the specified index, filling new positions with a user-specified value.

Features

• Assign to any index (positive or negative) on a deque, even if it's out of range.
• Automatically expands and fills new slots as needed.

Usage

from collections import deque
from expand_and_setitem import expand_and_setitem

d = deque([1, 2, 3])

expand_and_setitem(
    deque=d,
    index=5,
    value=99,
    fillvalue=0
)
print(d)  # deque([1, 2, 3, 0, 0, 99])

expand_and_setitem(
    deque=d,
    index=-8,
    value=42,
    fillvalue=None
)
print(d)  # deque([42, None, 1, 2, 3, 0, 0, 99])

Installation

pip install expand-and-setitem

Why?

The standard Python deque doesn't allow setting values out of range. This utility removes the need to manually expand the deque before assignment.
