Python中创建员工类Employee,属性有姓名name、能力值ability、年龄age(能力值100-年龄)，方法有doWork(),该方法执行一次，该员工的能力值减5，创建str()方法，打印该员工的信息

可以回答这个问题。以下是Python代码：

class Employee:
    def __init__(self, name, ability, age):
        self.name = name
        self.ability = ability
        self.age = age

    def doWork(self):
        self.ability -= 5

    def __str__(self):
        return f"Name: {self.name}, Ability: {self.ability}, Age: {self.age}"

employee1 = Employee("John", 90, 30)
employee1.doWork()
print(employee1)

输出结果为：

Name: John, Ability: 85, Age: 30
