A list where most (>95%) values will be None (or default)

Project description

Inspired by the post Populating a sparse list with random 1’s on StackOverflow.

A “sparse list” is a list where most (say, more than 95% of) values will be None (or some other default) and for reasons of memory efficiency you don’t wish to store these (cf. Sparse array).

This implementation has a similar interface to Python’s built-in list but stores the data in a dictionary to conserve memory.

Installation

sparse_list is available from PyPI - the Python Package Index (aka The Cheeseshop).

Installation is simply:

$ pip install sparse_list

Usage

See the unit-tests!
