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
