预测球赛比赛成绩 

一、选手比赛预测
 1 from random import random
 2 def printIntro():
 3     print("这个程序模拟两个选手A和B的某种竞技比赛")
 4     print("程序运行需要A和B的能力值（以0到1之间的小数表示）")
 5 def getInputs():
 6     a = eval(input("请输入选手A的能力值(0-1): "))
 7     b = eval(input("请输入选手B的能力值(0-1): "))
 8     n = eval(input("模拟比赛的场次: "))
 9     return a, b, n
10 def simNGames(n, probA, probB):
11     winsA, winsB = 0, 0
12     for i in range(n):
13         scoreA, scoreB = simOneGame(probA, probB)
14         if scoreA > scoreB:
15             winsA += 1
16         else:
17             winsB += 1
