a simple calculator

[Solstice]

I have tried something:

import time
run= True

def myfunc():
    a=input("first")
    b=input("second")
    c=int(a)+int(b)
    print(c)
 
class myClass:
    def __init__(self):
        print(myfunc())
        time.sleep(3)
        end=input("end?(Y/N)")
        if end=="Y":
            run= False

while run== True:
    myClass()

but it didn't really worked out
