预测球队比赛成绩

1、模拟体育竞技分析之羽毛球

代码为：

from random import random
def printIntro():
    print("该程序的制作者为学号2018310143118的同学")
    print("这个程序模拟两个选手A和B的羽毛球比赛")
    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("请输入模拟比赛的局数: "))
    return a, b, n
def simNGames(n, probA, probB):
    WinsA, WinsB = 0, 0
    winsA, winsB = 0, 0
    for i in range(1,n+1):
        scoreA, scoreB = simOneGame(probA, probB)
        if scoreA > scoreB:
            winsA += 1
        else:
            winsB += 1
        if i%3==0:
            if winsA>winsB:
                WinsA+=1
                print("第{}场胜利的为A".format(int(i/3)))
            else:
                WinsB+=1
                print("第{}场胜利的为B".format(int(i/3)))
            winsA,winsB=0,0
    return WinsA, WinsB

def gameOver(a,b):
    if a==30 or b==30:
        return True
    if a>19 and b>19:
        if abs(a-b)==2:
            return True
    if a<=19 or b<=19:
        if a==21 or b==21:
            return True
    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:
                scoreB +=1
                serving="B"
        else:
            if random() < probB:
                scoreB += 1
            else:
                scoreA += 1
                serving="A"
        return scoreA, scoreB
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 main():
    printIntro()
    probA, probB, n = getInputs()
    WinsA, WinsB = simNGames(n, probA, probB)
    printSummary(WinsA, WinsB)
main()

运行程序结果为（每三局为一场）：

运用 pyinstaller 打包该程序为可执行文件：

首先安装 pyinstaller 库：

pip install pyinstaller

调出命令行窗口：

输入代码文件的路径：

打包成功：

可在dist目录看到该文件：

 运行后为：

 2、模拟体育竞技分析之篮球

假设谁先得30分为胜利

代码为：

from random import random
def printIntro():
    print("该程序的制作者为学号2018310143118的同学")
    print("这个程序模拟两个队A和B的篮球比赛")
    print("程序运行需要队A和队B的能力值（以0到1之间的小数表示）")
def getInputs():
    a = eval(input("请输入队A的能力值(0-1): "))
    b = eval(input("请输入队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 gameOver(a,b):
    return a==30 or b==30
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):
    n = winsA + winsB
    print("竞技分析开始，共模拟{}场比赛".format(n))
    print("队A获胜{}场比赛，占比{:0.1%}".format(winsA, winsA/n))
    print("队B获胜{}场比赛，占比{:0.1%}".format(winsB, winsB/n))
def main():
    printIntro()
    probA, probB, n = getInputs()
    winsA, winsB = simNGames(n, probA, probB)
    printSummary(winsA, winsB)
main()
