世界杯买球算法

今年世界杯不太平，大家买球的输了不少吧，反正我一直在输，研究了下赔率和返还率，写了个算法，胜平负里面输入期中一个买入金额，输出其他两个金额。

返还率 = 预期收入 / 总投入

想算算威廉希尔和竞彩官方有没有稳赢的组合，结果没有。

    def __init__(self, winOdds, drawOdds, lossOdds):

        totalput = winput + drawput + lossput
        self.winper = winput / totalput
        self.drawper = drawput / totalput
        self.lossper = lossput / totalput

    def printf(self, win=None, draw=None, loss=None):

结果：
