Python - 彩票模拟器，模拟彩票的摇奖，并计算中奖概率，保本概率

---

1、代码

# 概率发生器
import random


# 配置
class Config:
    # 是否打印选配结果
    print_achievement = False
    # 测试轮次
    round_number = 100
    # 用户投注
    sale = 12

    # 玩法
    class PlayWay:
        # 开始数字
        start = 1
        # 结束数字
        end = 12
        # 玩法开出几个数字
        machine_choose = 5
        # 用户选择几个数字
        user_choose = 8
        # 最大赔率
        max_odds = 12.5
        # 平均赔率
        avg_odds = 12.5


# 生成随机票
def rg(q):
    u_list = []
    for i in range(q):
        ur = random.randint(Config.PlayWay.start, Config.PlayWay.end)
        if ur not in u_list:
            u_list.append(ur)
        else:
            while ur in u_list:
                ur = random.randint(Config.PlayWay.start, Config.PlayWay.end)
                if ur not in u_list:
                    u_list.append(ur)
                    break
    return u_list


if __name__ == '__main__':
    # 投赔率
    sale_odds_rate = Config.sale / Config.PlayWay.max_odds
    # 总注数
    count_sale = Config.round_number * Config.sale
    # 总成功次数
    count_success = 0
    for x in range(Config.round_number):
        if Config.print_achievement:
            print('-' * 15, 'round', x + 1, '-' * 15)
        m = rg(Config.PlayWay.machine_choose)
        if Config.print_achievement:
            print('machine', m)
        # 成功计次
        count = 0
        for j in range(Config.sale):
            u = rg(Config.PlayWay.user_choose)
            flag = False
            # 当玩法变化从少选到到复式时，包含方式相反
            if Config.PlayWay.machine_choose >= Config.PlayWay.user_choose:
                flag = set(u) <= set(m)
            else:
                flag = set(u) > set(m)
            if flag:
                if Config.print_achievement:
                    print('success', u)
                count += 1
            else:
                if Config.print_achievement:
                    print('fail', u)
        count_success += count
        if Config.print_achievement:
            print('success count', count)
    # 胜率
    print('success rate', format(count_success / count_sale * 100, '0.4f') + '%')
    # 保本率
    print('break even rate', format(count_success / count_sale * 100 * Config.PlayWay.max_odds, '0.4f') + '%')

2、运行结果

运行结果基本稳定在 4.5%-4.7% 左右

下面是运行12万注的结果

success rate 4.5083%
break even rate 56.3542%

3、玩法

可以根据不同的玩法设置不同的类型

如下是快乐彩12选5 任3的玩法配置

    # 玩法
    class PlayWay:
        # 开始数字
        start = 1
        # 结束数字
        end = 12
        # 玩法开出几个数字
        machine_choose = 5
        # 用户选择几个数字
        user_choose = 3
        # 最大赔率
        max_odds = 12.5
        # 平均赔率
        avg_odds = 12.5
