Generate professional pseudo-random number package in python.

Pure_PRNG

Generate professional pseudo-random number package in python.

Only the pseudo-random number algorithm with good statistical properties is implemented.

There are "methods" that specify the period of a multi-precision pseudo-random sequence.

Installation

Installation can be done through pip. You must have python version >= 3.8

pip install pure-prng

Usage

The statement to import the package:

from pure_prng_package import pure_prng

Example:

>>> seed = 170141183460469231731687303715884105727
>>> period = 115792089237316195423570985008687907853269984665640564039457584007913129639747

>>> prng_instance = pure_prng(seed)
>>> source_random_number = prng_instance.source_random_number()
>>> next(source_random_number)
