用python编写程序，模拟两个人进行猜拳比赛。具体要求如下：假设有A、B两名选手比赛采取，获得A选手和B选手各自出石头、剪刀、布的概率，分别为0.4、0.3、0.3;0.3、0.4、0.3。每局共出五次拳，赢三胜者获得本局胜利。问进行N局比赛，A和B各自获胜以及平局的场次和比例。并将程序封装。

好的，我可以帮你解决这个问题。以下是程序的实现：

import random

class Game:
    def __init__(self, a_probability, b_probability):
        self.a_probability = a_probability
        self.b_probability = b_probability
    
    def play(self):
        a_win = 0
        b_win = 0
        draw = 0
        for _ in range(5):
            a_choice = self.get_choice(self.a_probability)
            b_choice = self.get_choice(self.b_probability)
            if a_choice == b_choice:
                draw += 1
            elif (a_choice == 'rock' and b_choice == 'scissors') or \
                 (a_choice == 'scissors' and b_choice == 'paper') or \
                 (a_choice == 'paper' and b_choice == 'rock'):
                a_win += 1
            else:
                b_win += 1
        if a_win > b_win:
            return 'A'
        elif a_win < b_win:
            return 'B'
        else:
            return 'draw'
    
    def get_choice(self, probability):
        rand = random.random()
        if rand < probability[0]:
            return 'rock'
        elif rand < probability[0] + probability[1]:
            return 'scissors'
        else:
            return 'paper'

class Match:
    def __init__(self, a_probability, b_probability, n):
        self.a_probability = a_probability
        self.b_probability = b_probability
        self.n = n
    
    def play(self):
        a_win = 0
        b_win = 0
        draw = 0
        for _ in range(self.n):
            game = Game(self.a_probability, self.b_probability)
            result = game.play()
            if result == 'A':
                a_win += 1
            elif result == 'B':
                b_win += 1
            else:
                draw += 1
        a_ratio = a_win / self.n
        b_ratio = b_win / self.n
        draw_ratio = draw / self.n
        return a_win, b_win, draw, a_ratio, b_ratio, draw_ratio

上面的代码封装了两个类，`Game` 和 `Match`。`Game` 类用于表示一个五局比赛，`Match` 类用于表示进行多少局的比赛。在 `Game` 类中，`play()` 方法用于进行一局比赛，返回获胜者。`get_choice()` 方法用于根据给定的概率返回出拳的结果。在 `Match` 类中，`play()` 方法用于进行多局比赛，返回各种比赛结果的次数和比例。

下面是使用封装好的程序进行模拟的示例：

a_probability = [0.4, 0.3, 0.3]
b_probability = [0.3, 0.4, 0.3]
n = 1000

match = Match(a_probability, b_probability, n)
a_win, b_win, draw, a_ratio, b_ratio, draw_ratio = match.play()

print(f"A wins: {a_win} ({a_ratio:.2%})")
print(f"B wins: {b_win} ({b_ratio:.2%})")
print(f"Draws: {draw} ({draw_ratio:.2%})")

运行结果可能如下所示：

A wins: 416 (41.60%)
B wins: 467 (46.70%)
Draws: 117 (11.70%)

注意事项：在使用封装好的程序时，需要将 `a_probability` 和 `b_probability` 参数传入 `Match` 类的构造函数中。`a_probability` 和 `b_probability` 参数均为列表，分别表示 A 和 B 选手出石头、剪刀、布的概率。`n` 参数表示进行多少局比赛。
