True or false output based on a probability
Just use PyProbs library. It is very easy to use.
>>> from PyProbs import Probability as pr
>>>
>>> # You can pass float (i.e. 0.5, 0.157), int (i.e. 1, 0) or str (i.e. '50%', '3/11')
>>> pr.Prob(50/100)
False
>>> pr.Prob(50/100, num=5)
[False, False, False, True, False]
import random
def decision(probability):
return random.random() < probability
Given a function rand
that returns a number between 0 and 1, you can define decision
like this:
bool decision(float probability)
{
return rand()<probability;
}
Assuming that rand() returns a value in the range [0.0, 1.0)
(so can output a 0.0, will never output a 1.0).
