pyvarint

Varints, a method of serializing integers using one or more bytes

Generally in Python, integers are stored as long meaning that they will use at least 32 bits. When storing many numbers which do not require 32 bits, this would seem to be significantly wasteful; variable length representation should be able to assist in such cases.

Install

$ pip install pyvarint

Example

from random import sample
from pyvarint import decode, encode

ten_rand_ints = sample(range(100), 10)

for rand_int in ten_rand_ints:
    encoded = encode(rand_int)
    decoded = decode(encoded)
    assert decoded == rand_int
