对于分析出来的特征和行为用属性和方法进行表达

好的,以下是一个示例代码,用于表达分析出来的特征和行为:
```python
from abc import ABC, abstractmethod
# 抽象类 Traffic
class Traffic(ABC):
def __init__(self, speed, capacity):
self.speed = speed # 速度
self.capacity = capacity # 载人/货能力
@abstractmethod
def run(self):
pass
# 实体类 Car
class Car(Traffic):
def __init__(self, speed, capacity, length, width, height):
super().__init__(speed, capacity)
self.length = length # 车长
self.width = width # 车宽
self.height = height # 车高
def start(self):
print("Car starts.")
def accelerate(self):
print("Car accelerates.")
def brake(self):
print("Car brakes.")
def run(self):
print("Car runs on the road.")
# 实体类 Ship
class Ship(Traffic):
def __init__(self, speed, capacity, draft, length, width):
super().__init__(speed, capacity)
self.draft = draft # 吃水深度
self.length = length # 船长
self.width = width # 船宽
def sail(self):
print("Ship sails on the sea.")
def dock(self):
print("Ship docks at the port.")
def run(self):
print("Ship runs on the sea.")
# 实体类 Airplane
class Airplane(Traffic):
def __init__(self, speed, capacity, wingspan, altitude):
super().__init__(speed, capacity)
self.wingspan = wingspan # 翼展
self.altitude = altitude # 飞行高度
def take_off(self):
print("Airplane takes off.")
def land(self):
print("Airplane lands.")
def cruise(self):
print("Airplane cruises in the air.")
def run(self):
print("Airplane runs in the sky.")
```
在上面的代码中,抽象类Traffic中定义了两个属性speed和capacity,以及一个抽象方法run。实体类Car、Ship、Airplane继承了Traffic类,并在自身中增加了特有的属性和方法,同时实现了抽象方法run。
