排球比赛规则

代码如下：

 1 from random import random
 2 def printIntro():
 3     print("这个程序模拟A,B两个选手的比赛：\n")
 4     print("这个程序的实现需要知道A，B两个选手的能力值，该值为0-1之间的小数：\n")
 5 def getInputs():
 6     probA = eval(input("请输入A的能力值："))
 7     probB = eval(input("请输入B的能力值："))
 8     n=int(input("请输入比赛场次："))
 9     return probA,probB,n
10 def printSummary(winsA,winsB):
11     print("预计A会赢得{}场比赛".format(winsA))
12     print("预计B会赢得{}场比赛".format(winsB))
