、重写醉汉行走问题。使用Point类，每一步可以看作是利用随机参数创建的一个Point对象。Point类可能需要适当修改。

好的，让我来回答你的问题。对于重写醉汉行走问题，我可以提供以下代码：

import random

class Point:
    def __init__(self, x=0, y=0):
        self.x = x
        self.y = y

    def __str__(self):
        return f"({self.x}, {self.y})"

    def move(self, dx, dy):
        return Point(self.x + dx, self.y + dy)

class Drunk:
    def __init__(self, name):
        self.name = name

    def walk(self):
        steps = [(0, 1), (0, -1), (1, 0), (-1, 0)]
        return random.choice(steps)

class Field:
    def __init__(self):
        self.drunks = {}

    def add_drunk(self, drunk, location):
        self.drunks[drunk] = location

    def move_drunk(self, drunk):
        dx, dy = drunk.walk()
        current_location = self.drunks[drunk]
        new_location = current_location.move(dx, dy)
        self.drunks[drunk] = new_location

    def get_location(self, drunk):
        return self.drunks[drunk]

def walk(field, drunk, num_steps):
    start = field.get_location(drunk)
    for i in range(num_steps):
        field.move_drunk(drunk)
    return start.distance(field.get_location(drunk))

def simulate_walk(num_steps):
    drunk = Drunk('Jack')
    origin = Point(0, 0)
    field = Field()
    field.add_drunk(drunk, origin)
    for i in range(num_steps):
        walk(field, drunk, 1)
    return field.get_location(drunk)

def simulate_walks(num_steps, num_trials):
    for i in range(num_trials):
        end_location = simulate_walk(num_steps)
        print(end_location)

simulate_walks(10, 5)

这个代码使用了Point类来表示醉汉的位置，同时使用了Drunk类来表示醉汉的行走方式。Field类则用来管理醉汉的位置和移动。simulate_walk和simulate_walks函数用来模拟醉汉的行走，并输出最终的位置。
