Choose list variable given probability of each variable

Question

I\'ve been trying to code a program that uses the softmax activation function in the middle.

Right now, I have a list of probabilities like this:

P[0         


        

Answer 1

import random

probs = [0.1, 0.25, 0.6, 0.05]
r = random.random()
index = 0
while(r >= 0 and index < len(probs)):
  r -= probs[index]
  index += 1
print index - 1
