pure-prng 2.2.0

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
