No-Repeat Random

class NoRepeats(object):
    def __init__(self, index):
        self.lastround = secrets.randbelow(10) + 1

    def select(self):
        i = secrets.randbelow(10) + 1
        while i == self.lastround:
             i = secrets.randbelow(10) + 1
        self.lastround = i

Bot picks randomly, but avoids picking the same number it did the previous round.
