python程序运行后没反应,运行python程序后没有输出

我应该写一个名为Employee的类，其中包含姓名、薪水和工作年限的数据。它计算员工在退休时每月将收到的养老金支出，并显示employee对象的三个实例变量。它还调用Employee对象的pension方法来计算该雇员的每月养老金支出，并显示它。你知道吗

我在运行程序后没有得到任何输出，这就是具体的问题。

我应该得到这样的输出：Name: Joe Chen

Salary: 80000

Years of service: 30

Monthly pension payout: 3600.0

Process finished with exit code 0

这是完整的代码。你知道吗class Employee:

# init method implementation

def __init__(self, EmpName, EmpSalary, EmpYos):

self.EmpName = EmpName

self.EmpSalary = EmpSalary

self.EmpYos = EmpYos

def displayEmployeeDetails(self):

print "\nName ", self.EmpName,

# defines the salary details

def displaySalary(self):

print "\nSalary", self.EmpSalary

# defines the years of service

def displayYoservice(self):

print "\nYears of Service", self.EmpYos

# defines pension

def MonthlypensionPayout(self):

print "\nMonthly Pension Payout:", self.EmpSalary * self.EmpYos * 0.0015

def main():

# creates instance for employee 1
