python用类写抽奖

生成0-1随机数
random.random()

统计抽奖个数
import random

dict = {}
dict["一等奖"] = 0
dict["二等奖"] = 0
dict["三等奖"] = 0
for i in range(1000):
    acs = float("%.2f" % random.random())
    if acs < 0.08:
        dict["一等奖"] += 1
    elif 0.08 <= acs <= 0.3:
        dict["二等奖"] += 1
    else:
        dict["三等奖"] += 1
for i, j in dict.items():
    print("%s需要%d个" % (i, j))

用类的方式写
import random
class fcttest:
    def __init__(self,time):
        self.op = 0
        self.dic = {}
        self.dic["一等奖"] = 0
        self.dic["二等奖"] = 0
        self.dic["三等奖"] = 0
        self.time=time
    def chou(self):
        for i in range(self.time):
            self.op=float("%.2f"%random.random())
            if self.op < 0.08:
                self.dic["一等奖"] += 1
            elif 0.08 <= self.op <= 0.3:
                self.dic["二等奖"] += 1
            else:
                self.dic["三等奖"] += 1
    def __del__(self):
        for i, j in self.dic.items():
            print("%s  %d  " % (i, j))
ssr=int(input("输入抽奖次数"))
cj=fcttest(ssr)
cj.chou()

优化
rewardDict{
"一等奖":(0,0.08),
"二等奖":(0.08,0.3),
"三等奖":(0.3,1)
}
