Question

I want to generate random integers between 0-9 (inclusive on both ends), but I want to make sure it doesn’t often generate the same number consecutively. I plan to use the randint function from the random module. But I’m not sure if it will be handy. How often does random.randint generate the same number?

Answer 1

Why not wrap randint?

class MyRand(object):
    def __init__(self):
        self.last = None

    def __call__(self):
        r = random.randint(0, 9)
        while r == self.last:
            r = random.randint(0, 9)
        self.last = r
        return r

randint = MyRand()
x = randint()
y = randint()
...
