How to change the class of son's function which inherited from father class?

To change the class of a son's function that is inherited from a father class, you can create a new class that inherits from the father class and override the son's function in the new class with the desired behavior. Alternatively, you can also directly modify the son's function in the son class to change its behavior, but this may not be recommended if you want to maintain the integrity of the original father class.

please give a example about how to implement son class and father class by python
Sure, here is an example of implementing a subclass and superclass (father class) relationship in Python:
class Father:
def __init__(self, name):
self.name = name
class Son(Father):
def __init__(self, name, age):
Father.__init__(self, name)
self.age = age
father = Father("John")
son = Son("David", 20)
print(father.name)
print(son.name)
print(son.age)
In this example, Father is the superclass and Son is the subclass. The Son class inherits from the Father class using the syntax "class Son(Father):", indicating that the Son class is a subclass of the Father class.
The init function of the Son class includes both the "name" parameter from the Father class as well as a new "age" parameter specific to the Son class. It calls the init function of the Father class and passes the "name" parameter using the syntax "Father.__init__(self, name)".
When creating instances of the Father and Son classes, we can see that the Son instance has both the name attribute inherited from the Father class and the age attribute specific to the Son class.
Modify the Bat class to implement Flyable too.
To modify the Bat class to implement the Flyable interface, we can simply add the necessary methods to the class definition, as shown below:
```
public class Bat extends Animal implements Flyable {
@Override
public boolean canEat() {
// implementation for canEat method
return true;
}
@Override
public void takeOff() {
// implementation for take off
System.out.println("Bat is taking off by flying.");
}
@Override
public void land() {
// implementation for landing
System.out.println("Bat is landing by flying.");
}
}
```
In this modified implementation, the Bat class now extends the Animal class and implements the Flyable interface. It provides its own implementation of the canEat() method inherited from the Animal class, as well as the takeOff() and land() methods defined in the Flyable interface.
