Est-il possible de faire une boucle de script python et de recommencer

est-il possible de rendre un programme revenir à son état d'origine après sa course. Par exemple, j'ai fait un script de calculatrice ci-dessous. Est-il possible de commencer à démarrer après la sortie d'une réponse au lieu de l'utilisateur ayant à quitter le script et de la réexécuter. Code:

class bcolors:
    Red = '\033[91m'
    Green = '\033[92m'
    Blue = '\033[94m'
    Cyan = '\033[96m'
    White = '\033[97m'
    Yellow = '\033[93m'
    Magenta = '\033[95m'
    Grey = '\033[90m'
    Black = '\033[90m'
    Default = '\033[99m'
#code for addition
def addition(x, y):
        return x + y
#code for subtraction
def subtraction(x, y):
        return x - y
#code for multiplication
def multiplication(x, y):
        return x * y
#code for division
def division(x, y):
        return x / y

print(bcolors.Blue + "Hey and welcome to my first python program")
print("This is a calculater I made in my spare time!")
print(bcolors.Magenta + "Simply type in your question here and you will get answer.")
print(bcolors.Red + "This program is made by and credited to Mohammad Al Nesef")
print(bcolors.Yellow + "1.addition")
print(bcolors.Yellow + "2.subtraction")
print(bcolors.Yellow + "3.multiplication")
print(bcolors.Yellow +"4.division")
choice = input(bcolors.Green + "Enter choice(1/2/3/4: ")
num1 = input(bcolors.Blue + "Enter first number: ")
num2 = (input(bcolors.Magenta + "Enter second number: "))
if choice == '1':
        print(float(num1), "+", float(num2), "=",  addition(num1,num2))

elif choice == "2":
        print(float(num1), "-", float(num2), "=", subtraction(num1,num2))

elif choice == "3":
        print(float(num1), "*", float(num2), "=", multiplication(num1,num2))

elif choice == "4":
        print(float(num1), "/", float(num2), "=", division(num1,num2))

else:
        print("Invalid Input")
