RandDist 0.0.4

A random number generator with custom probability distribution

RandDist

python random generator with custom probability distribution

This minimal package generates a list of int or float numbers within a specific range and steps with custom probability distribution.

How to use

install

pip install randdist

include

import randdist

generate

numbers_list, sample_number = randdist.randint(0, 10, formula = lambda x:x**2)

Methods

• randint: Generates integer numbers
• randfloat: Generates float numbers

Parameters

• min_value: start
• max_value: stop
• step: bin step size default = 1
• formula: lambda function for distribution curve default = lambda x:x
• seeds: # of generated numbers default = 1000

Outputs

• list: a list of shuffled generated numbers
• sample: picks one from the list

Demo

• min_value = -3
• max_value = 3
• step = 0.5
• formula = lambda x:12-(x**2)
• seeds = 1000

# generate int numbers
random_list_int, sample_int = randdist.randint(min_value, max_value, step, formula, seeds)

# generate float numbers
random_list_float, sample_float = randdist.randfloat(min_value, max_value+step, step, formula, seeds)

Test Distribution

with 10K generated numbers

# pick samples from 10K generated list of numbers
generated_list = []
for i in range(10000):
    _, sample_int = randdist.randint(-3, 3, 0.5, lambda x:12-(x**2))
    generated_list.append(sample_int)
