## 用python进行体育竞技分析 ##

**话不多说，直接上代码！**

from random import random
    
    def printInfotro():
        print("这个程序模拟两个选手A和B的某种竞技比赛")
        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)")
    
    def getInputs():
        a = eval(input("请输入选手A的能力值（0-1）："))
        b = eval(input("请输入选手B的能力值（0-1）："))
        n = eval(input("模拟比赛的场次："))
        return a,b,n
    
    def printSummary(winsA,winsB):
        n = winsA+winsB
        print("竞技分析开始，共模拟{}场比赛".format(n))
        print("选手A获胜{}场比赛，占比{:0.1%}".format(winsA,winsA/n))
        print("选手B获胜{}场比赛，占比{:0.1%}".format(winsB,winsB/n))
    
    def simNGames(n,probA,probB):
        winsA,winsB = 0,0
        for i in range(n):
            scoreA,scoreB = simOneGame(probA,probB)
            if scoreA>scoreB:
                winsA += 1
            else:
                winsB += 1
        return winsA,winsB
    
    def simOneGame(probA,probB):
        scoreA,scoreB = 0,0
        serving = 'A'
        while not gameOver(scoreA,scoreB):
            if serving == "A":
                if random() < probA:
                    scoreA+=1
                else:
                    serving="B"
            else:
                if random() < probB:
                    scoreB+=1
                else:
                    serving="A"
        return scoreA,scoreB
    
    def gameOver(a,b):
        return a==15 or b==15
    
    def main():
        printInfotro()
        probA,probB,n=getInputs()
        winsA,winsB=simNGames(n,probA,probB)
        printSummary(winsA,winsB)
    
    main()

**运行结果如下：**
