一:羽毛球比赛设计

from random import random
def printIntro():
    print("27号程序模拟选手A,B,C,D进行左右边羽毛球比赛(27)")
    print("27号程序运行需要A,B,C,D的能力值(0-1)")
def getInputs():
    z=eval(input("请输入左场次选手的能力值(0-1):"))
    y=eval(input("请输入右场次选手的能力值(0-1):"))
    n=eval(input("模拟比赛的场次:"))
    return z,y,n
def simNGames(n,probZ,probY):
    winsZ,winsY=0,0
    for i in range(n):
        scoreZ,scoreY=simOneGame(probZ,probY)
        if scoreZ>scoreY:
            winsZ+=1
        else:
            winsY+=1
    return winsZ,winsY

    else:
        return False

    scoreZ,scoreY=0,0
    serving="Z"

                scoreZ+=1
            else:
                serving="Y"
        else:
            if random()<probY:
                scoreY+=1
            else:
                serving="Z"
    return scoreZ,scoreY
def printSummary(winsZ,winsY):
    n=winsZ+winsY
    print("竞技分析开始，共模拟()场比赛".format(n))
    print("选手C,D获胜{}场比赛,占比{：0.1%}".format(winsZ,winsZ/n))
    print("选手A,B获胜{}场比赛，占比{：0.1%}".format(winsY,winsY/n))
def main():
    printIntro()
    probZ,probY,n=getInputs()
    winsZ,winsY=simNGames(n,probZ,probY)
    printSummary(winsZ,winsY)
main()

二：足球比赛设计

from random import random
def printIntro():
    print("27号程序模拟选手A,B进行足球比赛(27)")
    print("27号程序运行需要A,B的能力值(0-1)")
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
    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(scoreA,scoreB):
    return scoreA==15 or scoreB==15
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))

三：晋级模拟

from random import random

    return winsA,winsB
def simOneGame(probA,probB):
    scoreA,scoreB=0,0
    serving="A"

    return scoreA,scoreB
def gameOver(scoreA,scoreB):
    return (scoreA >= 11 and abs(scoreA-scoreB)>=2) or (scoreB >= 11 and abs(scoreA-scoreB)>=2)
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))
