关于预测比赛结果
作者:互联网
今天给各位介绍如何用Python编写一段预测比赛结果的代码
以排球比赛为例
首先介绍一下排球比赛的规则
前四场采用25分制,每场比赛只有到某支队伍先取得25分并且比对手至少高三分才算获得本局胜利;
正式比赛采用五局三胜制,最后的决赛局只采用15分制,当其中一队先得满8分以后,双方交换场地,按原位置继续进行比赛
决胜局的优胜条件为先取得15分及15分以上且比对手得分高2分以上的队伍获胜
我设计了如下程序
# -*- coding: utf-8 -*- """ Created on Wed May 15 15:43:44 2019 @author: h2446 """ from random import random def printIntro(): print("这个程序模拟两支排球队A和B的排球比赛") 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("请输入队伍A的能力值(0~1):")) b=eval(input("请输入队伍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): if (a>25 and abs(a-b)>=2 )or(b>25 and abs(a-b)>=2): 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: serving="B" else: if random()<probB: scoreB +=1 else: serving="A" return scoreA,scoreB def final(probA,probB): winsA,winsB=simNGames1(4,probA,probB) printSummary(winsA,winsB) if not winsA==3 or winsB==3: if winsA==winsB==2: winsA1,winsB1=simOneGame1(probA,probB) finalprintSummary(winsA,winsB) else: finalprintSummary(winsA,winsB) def simNGames1(n,probA,probB): winsA,winsB=0,0 for i in range(n): scoreA,scoreB=simOneGame2(probA,probB) if winsA==3 or winsB==3: break if scoreA>scoreB: winsA+=1 else: winsB+=1 return winsA,winsB def simOneGame2(probA,probB): scoreA,scoreB=0,0 serving="A" while not GG(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 simOneGame1(probA,probB): scoreA,scoreB=0,0 serving="A" while not finalGameOver(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 GG(a,b): return a==3 or b==3 def finalGameOver(a,b): if (a==8 or b==8): if a>b: print("A队获得8分,双方交换场地") else: print("B队获得8分,双方交换场地") if (a>15 and abs(a-b)>=2 )or(b>15 and abs(a-b)>=2): return True else: return False def finalprintSummary(winsA,winsB): n=winsA+winsB if n>=4: print("进行最终决赛") if winsA>winsB: print("最终决赛由A获胜") else: print("最终决赛由B获胜") else: if winsA>winsB: print("最终决赛由A获胜") else: print("最终决赛由B获胜") 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) final(probA,probB) main()
运行结果为
以上的便是今天的学习
