怎样输出呢？给我写不会了，不知道怎么调用输出最后结果

Question

#定义一个Calculator类
class Calculator:
    def __init__(self):
        self.num1 = 0
        self.num2 = 1
    #类方法加add
    def add(num1,num2):
        x= num1+num2
        print('%d+%d='%(num1,num2),x)
    #类方法减minus
    def minus(num1,num2):
        x= num1-num2
        print('%d-%d='%(num1,num2),x)
    #类方法乘mulitiple
    def mulitiple(num1,num2):
        x= num1*num2
        print('%d*%d='%(num1,num2),x)
    #类方法除divide
    def divide(num1,num2):
        x= num1/num2
        print('%d/%d='%(num1,num2),x)
number1=input("请输入第一个操作数：")
number2=input("请输入第二个操作数：")
if number1.isdigit() and number2.isdigit():
    q=Calculator()
    q.num1=int(number1)
    q.num2=int(number2)
    open=input("请输入您需要的操作+-*/：")
        缺输出条件
else:
    print('操作数输入有误，必须输入整数！')
