Generate random number between 0.1 and 1.0. Python

Question

I\'m trying to generate a random number between 0.1 and 1.0. We can\'t use rand.randint because it returns integers. We have also tried random.uniform(0.1

Answer 1

With the information you've given (including comments thus far), I still fail to see how the university is going to test your program such that it will make a difference if 1.0 appears or not. (I mean, if you're required to generate random floats, how can they require that any particular value appears?)

OK, so putting the craziness of your requirements aside:

The fact that the lower bound for your random floats is higher than 0 gives you a disturbingly elegant way to use random.random, which guarantees return values in the interval [0.0, 1.0): Simply keep calling random.random, throwing away any values less than 0.1, except 0.0. If you actually get 0.0, return 1.0 instead.

So something like

from random import random

def myRandom():
    while True:
        r = random()
        if r >= 0.1:
            return r
        if r == 0.0:
            return 1.0
