如何完善最后乒乓球比赛的代码

为了完善乒乓球比赛的代码，可以从以下几个方面入手：

### 1. 处理 11 分平分时的获胜判断
在实际乒乓球比赛中，当双方都达到 11 分时，必须有一方领先 2 分才能赢得该局。因此，需要在模拟每一局的逻辑中加入这一判断条件。

#### 修改后的 `RunSet` 方法：

def RunSet(self):
    while self.score1 < 11 and self.score2 < 11:
        if self.RunScore():
            self.score1 += 1
        else:
            self.score2 += 1
    
    # 处理 11 分平分的情况
    while abs(self.score1 - self.score2) < 2 and max(self.score1, self.score2) >= 11:
        if self.RunScore():
            self.score1 += 1
        else:
            self.score2 += 1
    
    if self.score1 > self.score2:
        self.setWinner = self.player1
    else:
        self.setWinner = self.player2

### 2. 改进球员能力的建模
当前球员的能力仅用一个数值表示，这过于简化了现实情况。可以考虑引入多个维度来表示球员的能力，例如发球能力、接球能力、防守能力和进攻能力等。

#### 新的 `Player` 类：

class Player:
    def __init__(self, name, nationality, serving_ability, receiving_ability, defense_ability, offense_ability):
        self.name = name
        self.nationality = nationality
        self.serving_ability = serving_ability
        self.receiving_ability = receiving_ability
        self.defense_ability = defense_ability
        self.offense_ability = offense_ability

    def show_info(self):
        print(f"Name: {self.name}, Nationality: {self.nationality}")
        print(f"Serving Ability: {self.serving_ability}, Receiving Ability: {self.receiving_ability}")
        print(f"Defense Ability: {self.defense_ability}, Offense Ability: {self.offense_ability}")

#### 修改 `RunScore` 方法以考虑多维度能力：

import random

def RunScore(self):
    # 计算综合能力值
    ability_diff = (self.player1.serving_ability + self.player1.offense_ability) - (self.player2.receiving_ability + self.player2.defense_ability)
    
    # 转换为概率
    p = (ability_diff / 200) * 2 + 0.5
    
    # 随机生成一个 [0, 1) 之间的数
    r = random.random()
    
    return r < p

### 3. 程序结构优化与重构
为了提高代码的可维护性和可扩展性，可以进行以下优化：

#### 解耦逻辑和显示
将逻辑部分和显示部分分离，使代码更加清晰和易于维护。

##### 逻辑部分：

class Match:
    def __init__(self, player1, player2):
        self.player1 = player1
        self.player2 = player2
        self.setScore1 = 0
        self.setScore2 = 0
        self.matchWinner = None
        self.allSets = []

    def RunMatch(self):
        for _ in range(5):
            new_set = Set(self.player1, self.player2, len(self.allSets) + 1)
            new_set.RunSet()
            self.allSets.append(new_set)
            
            if new_set.setWinner == self.player1:
                self.setScore1 += 1
            else:
                self.setScore2 += 1
            
            if self.setScore1 == 3 or self.setScore2 == 3:
                self.matchWinner = self.player1 if self.setScore1 > self.setScore2 else self.player2
                break

    def show_result(self):
        print(f"{self.player1.name} vs {self.player2.name} {self.setScore1}:{self.setScore2}")
        if self.matchWinner:
            print(f"{self.matchWinner.name} wins the match")
        
        for set_ in self.allSets:
            set_.show_result()

##### 显示部分：

class Set:
    def __init__(self, player1, player2, set_number):
        self.player1 = player1
        self.player2 = player2
        self.setNumber = set_number
        self.score1 = 0
        self.score2 = 0
        self.setWinner = None
        self.allScores = []

    def RunSet(self):
        while self.score1 < 11 and self.score2 < 11:
            if self.RunScore():
                self.score1 += 1
            else:
                self.score2 += 1
        
        while abs(self.score1 - self.score2) < 2 and max(self.score1, self.score2) >= 11:
            if self.RunScore():
                self.score1 += 1
            else:
                self.score2 += 1
        
        if self.score1 > self.score2:
            self.setWinner = self.player1
        else:
            self.setWinner = self.player2
        
        self.allScores.append((self.score1, self.score2))

    def RunScore(self):
        ability_diff = (self.player1.serving_ability + self.player1.offense_ability) - (self.player2.receiving_ability + self.player2.defense_ability)
        p = (ability_diff / 200) * 2 + 0.5
        r = random.random()
        return r < p

    def show_result(self):
        print(f"{self.player1.name} vs {self.player2.name} - 第 {self.setNumber} 局比赛开始")
        for score in self.allScores:
            print(f"{score[0]}:{score[1]}")
        print(f"{self.setWinner.name} 获胜")

通过以上改进，代码不仅更加符合实际比赛规则，而且更具可读性和可维护性。
