python 实现红包随机生成算法的简单实例

实例如下：

    </pre><pre name="code" class="python">#! /usr/bin/python
    # -*- coding: utf-8 -*-

    import random
    class CDispatch:

     def __init__(self,sum,count):
      self.sum = sum
      self.count=count
      #print 'init here sum =',sum,',count =',count
     def __del__(self):
      pass
      #print 'run del the class'
     def getListInfo(self):
      listInfo=[]
      sumMoney = self.sum*100

      for num in range(0,self.count):
       if(num == self.count -1):
        listInfo.append(float('%0.2f'%sumMoney)/100)
        break
       bigRand=sumMoney+1+num-self.count
       #print 'sumMoney=',sumMoney,'num=',num,'self.count=',self.count,'big=',bigRand
       try:
        a = random.randint(1,int(bigRand))
       except:
        for i in range(0,num):
         print 'listInfo[%d]'%i,'=',listInfo[i]
        if num >0:
         print 'sumMoney=',sumMoney,'num=',num,'listInfo[num-1]=',listInfo[num-1],'self.count=',self.count,'big=',bigRand
       #print 'a=',a
        break
       sumMoney -=a
       listInfo.append(float(a)/100)

      return listInfo

    for i in range(0,100000):

     dispatch = CDispatch(1.05,5)
     listGet = dispatch.getListInfo()
     print listGet

     del dispatch
