编程实现类的继承。编写父类People，子类Employee继承自人类。人类具有姓名，性别，年龄等性质，还具有吃和说的行为。雇员类继承父类，还拥有工号性质和工作行为。构造人类和员工类的对象，调用吃、说、工作的方法输出有关信息。

好的，以下是实现上述功能的Python代码：

class People:
    def __init__(self, name, gender, age):
        self.name = name
        self.gender = gender
        self.age = age

    def eat(self):
        print(f"{self.name} is eating.")

    def speak(self):
        print(f"{self.name} is speaking.")


class Employee(People):
    def __init__(self, name, gender, age, employee_id):
        super().__init__(name, gender, age)
        self.employee_id = employee_id

    def work(self):
        print(f"{self.name} is working with employee ID {self.employee_id}.")


# 创建People类对象
p1 = People("Tom", "Male", 25)
p1.eat()  # Tom is eating.
p1.speak()  # Tom is speaking.

# 创建Employee类对象
e1 = Employee("Jerry", "Male", 30, "001")
e1.eat()  # Jerry is eating.
e1.speak()  # Jerry is speaking.
e1.work()  # Jerry is working with employee ID 001.

运行结果为：

Tom is eating.
Tom is speaking.
Jerry is eating.
Jerry is speaking.
Jerry is working with employee ID 001.
