python写简单农场小游戏

好的，下面是一个简单的农场小游戏示例：

import random

class Crop:
    def __init__(self, growth_rate, water_need, light_need):
        self._growth = 0
        self._days_growing = 0

    game.play()

在上面的代码中，我们定义了三个类：Crop、Wheat和Potato。Crop是一个基类，而Wheat和Potato是Crop的子类。我们还定义了一个Farm类和一个Game类。

Game类是我们的游戏主类。它包含一个Farm对象和游戏的主要循环。在每个循环中，玩家可以选择四种不同的操作：生长作物、收获小麦、收获土豆和结束一天。每个操作都会影响玩家的水和光等级，并且可能会触发随机事件，例如暴风雨或热浪。

Farm类包含一组作物。它有一个grow_crops方法，用于生长所有作物，并且有一个report_crops方法，用于打印每个作物的状态。它还有一个harvest_crop方法，用于收获特定类型的作物。

Crop类是作物的基类。它有一些属性，例如_growth和_days_growing，用于追踪作物的成长过程。它还有一些方法，例如needs、report和grow，这些方法用于管理作物的需求和状态。Wheat和Potato类是Crop的子类，它们分别代表小麦和土豆作物。它们覆盖了一些Crop的方法，并定义了自己的特定需求和状态。
