羽毛球模拟比赛

1. 21 分制,3局2胜为佳 
2. 每球得分制 
3. 每回合中,取胜的一方加 1 分 
4. 当双方均为 20 分时,领先对方 2 分的一方赢得该局比赛 
5. 当双方均为 29 分时,先取得 30 分的一方赢得该局比赛 
6. 一局比赛的获胜方在下一局率先发球

代码如下:

from random import random
print("学号尾数17")
def printIntro():
    
    print("这个程序模拟两个选手A和B的羽毛球竞技比赛")
    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 simNGames(n, probA, probB):
    winsA, winsB = 0, 0
    scoreA_ls=[]
    scoreB_ls=[]
    for i in range(n):
        scoreA, scoreB = simOneGame(probA, probB)
        scoreA_ls.append(scoreA)
        scoreB_ls.append(scoreB)
        if scoreA > scoreB:
            winsA += 1
        else:
            winsB += 1
    return winsA, winsB,scoreA_ls,scoreB_ls
def gameOver(a,b):
    if(a>=20 or b>=20):
        if(abs(a-b)==2 and a<=29 and b<=29):
            return True
        else:
            return a==30 or b==30
    else:
        return False
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 printSummary(winsA, winsB,scoreA_ls,scoreB_ls):
    n = winsA + winsB
    print("竞技分析开始,共模拟{}场比赛".format(n))
    print("A选手各场次得分比分:")
    print(scoreA_ls)
    print("B选手各场次得分比分:")
    print(scoreB_ls)
    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 main():
    printIntro()
    probA, probB, n= getInputs()
    winsA, winsB,scoreA_ls,scoreB_ls = simNGames(n, probA, probB)
    printSummary(winsA, winsB,scoreA_ls,scoreB_ls)
    
main()

运行结果如下:
