I’m trying to make this code go back to the top of the program instead of ending at the printed string after the first if statement.

num_1 = (input("Please enter a whole number: "))
num_2 = (input("Please enter a second whole number: "))
if num_1.find (".") != -1 or num_2.find(".")!= -1:
   print("sorry enter a whole number"):
else:
  print("numbers are whole perform the calculation")
  num_1 = int(num_1)
  num_2 = int(num_2)

  print(f"{num_1} + {num_2} = {num_1 + num_2} ")

I have tried everything I can think of, but I’m new to this so any help would be appreciated.
