Running a program that ends in a yes/no response. I need the "yes" response to trigger the program to ask the same questions as when the program started....

 

Example:

def multiply (a,b):
 return a*b

a = float(input("What is the price of each tablet?"))
b = float(input("How many tablets are you purchasing?"))
SalesTax = .10
Shipping = 15
Subtotal = (a*b)
print(f"Your Subtotal is:",(a*b))
print(f"Sales Tax:" (SalesTax))
print (f"Shipping:" (Shipping))
response = input(f"Anything Else? (Y/N)")
if response == "Y":
 -this is where I'm stuck-
if response == "N":
   print ("Have a nice day!")
     break
