python定义员工类，每个员工包含姓名和薪资属性，统计员工总人数与总薪资。 创建员工对象，输出员工的信息，输出员工总人数和总薪资，并计算2位员工的薪资的和

好的，我来给您写一个 Python 的员工类示例代码：

class Employee:
    total_employees = 0
    total_salary = 0

    def __init__(self, name, salary):
        self.name = name
        self.salary = salary
        Employee.total_employees += 1
        Employee.total_salary += salary

    def __str__(self):
        return f"Name: {self.name}, Salary: {self.salary}"

# 创建员工对象
emp1 = Employee("Tom", 5000)
emp2 = Employee("Jerry", 6000)

# 输出员工信息
print(emp1)
print(emp2)

# 输出员工总人数和总薪资
print("Total employees:", Employee.total_employees)
print("Total salary:", Employee.total_salary)

# 计算2位员工的薪资的和
sum_salary = emp1.salary + emp2.salary
print("Sum of 2 employees' salary:", sum_salary)

输出结果如下：

Name: Tom, Salary: 5000
Name: Jerry, Salary: 6000
Total employees: 2
Total salary: 11000
Sum of 2 employees' salary: 11000

以上就是一个简单的员工类示例，您可以根据自己的需要进行修改和扩展。
