Drop-in Replacement for the Python Random Module.

Project description

Pyewacket

Fast, fault-tolerant, drop-in replacement for the Python3 random module

Built on top of the RNG Storm Engine for stability and performance. Storm is a high quality random engine, but totally not appropriate for cryptography of any kind. Pyewacket is meant for games, data science, A.I. and experimental programming, not security.

Quick Install $ pip install Pyewacket

Installation may require the following:

  • Python 3.6 or later with dev tools (setuptools, pip, etc.)
  • Cython: pip install Cython
  • Modern C++17 Compiler and Standard Library.

Random Generators

Random Integers

  • Pyewacket.randbelow(n: int) -> int
    • While randrange(a, b, c) can be handy, it's more complex than needed most of the time.
    • @param n :: Pyewacket expands the acceptable input domain to include non-positive values of n.
    • @return :: random integer in range (n, 0] or [0, n) depending on the sign of n.
from Pyewacket import randbelow


""" Standard """
randbelow(10)       # -> [0, 10)

""" Extras """
randbelow(0)        # -> [0, 0) => 0
randbelow(-10)      # -> (-10, 0]
  • Pyewacket.randint(a: int, b: int) -> int
    • @param a, b :: both are required,
    • @return :: random integer in range [a, b] or [b, a]
    • Inclusive on both sides
    • Removed the asymmetric requirement of a < b
    • When a == b returns a
from Pyewacket import randint


""" Standard """
randint(1, 10)      # -> [1, 10]

""" Extras """
randint(10, 1)      # -> [1, 10]
randint(10, 10)     # -> [10, 10] => 10
  • Pyewacket.randrange(start: int, stop: int = 0, step: int = 1) -> int
    • Fault tolerant and faster than random.randrange()
    • @param start :: This is the starting point for the distribution range so long as start <= stop and step >= 0
    • @param stop :: optional, default=0, stating point iff stop < start.
    • @parma step :: optional, default=1, negative stepping will flip start and stop.
      • The sign of the step controls the phase of the output, said another way: negative ranges count backwards.
    • @return :: random integer in range (stop, start] or [start, stop), by increments of |step|
    • Removed the requirements of start < stop, and step > 0
    • Always returns start iff start == stop or step == 0, ie the empty range.
from Pyewacket import randrange


""" Standard """
randrange(10)           # -> [0, 10) by whole numbers
randrange(1, 10)        # -> [1, 10) by whole numbers
randrange(1, 10, 2)     # -> [1, 10) by 2, odd numbers

""" Extras """
randrange(-10)          # -> [-10, 0) by 1
randrange(10, 1)        # -> [1, 10) by 1
randrange(10, 0, 2)     # -> [0, 10) by 2, even numbers
randrange(10, 10, 0)    # -> [10, 10) => 10

Random Floating Point

  • Pyewacket.random() -> float
    • random float in range [0.0, 1.0] or [0.0, 1.0) depending on rounding, platform specific.
    • This is the only function that doesn't show a performance increase, as expected - Random.random() is highly optimized.
  • Pyewacket.uniform(a: float, b: float) -> float
    • random float in [a, b] or [a, b) depending on rounding
    • 4x faster
  • Pyewacket.expovariate(lambd: float) -> float
    • 5x faster
  • Pyewacket.gammavariate(alpha, beta) -> float
    • 10x faster
  • Pyewacket.weibullvariate(alpha, beta) -> float
    • 4x faster
  • Pyewacket.betavariate(alpha, beta) -> float
    • 16x faster
  • Pyewacket.paretovariate(alpha) -> float
    • 4x faster
  • Pyewacket.gauss(mu: float, sigma: float) -> float
    • 10x faster
  • Pyewacket.normalvariate(mu: float, sigma: float) -> float same as Pyewacket.gauss()
    • 10x faster
  • Pyewacket.lognormvariate(mu: float, sigma: float) -> float
    • 10x faster
  • Pyewacket.vonmisesvariate(mu: float, kappa: float) -> float
    • 4x faster
  • Pyewacket.triangular(low: float, high: float, mode: float = None)
    • 10x faster

Random Sequence Values

  • Pyewacket.choice(seq: List) -> Value
    • An order of magnitude faster than random.choice().
    • @param seq :: any zero indexed object like a list or tuple.
    • @return :: random value from the list, can be any object type that can be put into a list.
  • Pyewacket.choices(population, weights=None, *, cum_weights=None, k=1)
    • @param population :: data values
    • @param weights :: relative weights
    • @param cum_weights :: cumulative weights
    • @param k :: number of samples to be collected
    • Only seeing a 2x performance gain.
  • Pyewacket.cumulative_weighted_choice(table, k=1)
    • 10x faster than choices, but radically different API and a bit less flexible.
    • Supports Cumulative Weights only. Convert relative weights to cumulative if needed: cum_weights = tuple(itertools.accumulate(rel_weights))
    • @param table :: two dimensional list or tuple of weighted value pairs. [(1, "a"), (10, "b"), (100, "c")...]
      • The table can be constructed as tuple(zip(cum_weights, population)) weights always come first.
    • @param k :: number of samples to be collected. Returns a list of size k if k > 1, otherwise returns a single value - not a list of one.
  • Pyewacket.shuffle(array: list) -> None
    • Shuffles a list in place.
    • @param array :: must be a mutable list.
    • Approximately 20 times faster than random.shuffle().
    • Implements Knuth B Shuffle Algorithm. Knuth B is twice as fast as Knuth A or Fisher-Yates for every test case. This is likely due to the combination of walking backward and rotating backward into the back side of the list. With this combination it can never modify the data it still needs to walk through. Fresh snow all the way home, aka very low probability for cache misses.
  • Pyewacket.sample(population: List, k: int) -> list
    • @param population :: list or tuple.
    • @param k :: number of unique samples to get.
    • @return :: size k list of unique random samples.
    • Performance gains range (5x to 20x) depending on len(population) and the ratio of k to len(population). Higher performance gains are seen as k approaches pop size.

Hardware & Software Seeding

  • seed(seed: int=0) -> None
    • Hardware seeding is enabled by default. This function is used to turn toggle software seeding and set or reset the engine seed. This affects all random functions in the module.
    • @param seed :: any non-zero positive integer less than 2**63 enables software seeding.
    • Calling seed() or seed(0) will turn off software seeding and re-enable hardware seeding.
    • While you can toggle software seeding on and off and re-seed the engine at will without error, this function is not intended to be used inside a tight loop. General rule: seed once, or better yet, not at all. Typically, software seeding is for debugging a product, hardware seeding is used for product release. Please don't use software seeding for the release version of a game!
