How Can I Make The Program To Rerun Itself In Python?

I am a beginner in programming right now and i know very less basic. I tried to create a calculator in python and it worked but i cant get it to rerun itself i have tried things on

Solution 1:

Loop over that code and break when you want to stop repeating:

whileTrue: # Will start repeating here
    num1 = input("Enter your 1st number: ")
    num2 = input("Enter your 2nd number: ")
    choose_ope = input("Choose your operator: ")
    if choose_ope == '+':
        print(float(num1) + float(num2))
    elif choose_ope == '-':
        print(float(num1) - float(num2))
    elif choose_ope == '*':
        print(float(num1) * float(num2))
    elif choose_ope == '/':
        print(float(num1) / float(num2))

    go_again = input("Do you want to go again ? : Y/N\n")
    if go_again != 'Y':
        print("OK!! Exiting")
        break# break to leave the loop# It will loop automatically back to the top otherwise

Solution 2:

We can do this by writing this in a function and make it as recursive function like below.

defcalculator():
    num1 = input("Enter your 1st number: ")
    num2 = input("Enter your 2nd number: ")
    choose_ope = input("Choose your operator: ")
    if choose_ope == '+':
        print(float(num1) + float(num2))
    elif choose_ope == '-':
        print(float(num1) - float(num2))
    elif choose_ope == '*':
        print(float(num1) * float(num2))
    elif choose_ope == '/':
        print(float(num1) / float(num2))

    go_again = input("Do you want to go again ? : Y/N\n")
    if go_again == 'Y':
        calculator()
    else:
        print("OK!!")

calculator()

Solution 3:

You can use a while loop that will run the code again until the input is different from Y:

go_again = 'Y'while go_again == 'Y':
    num1 = input("Enter your 1st number: ")
    num2 = input("Enter your 2nd number: ")
    choose_ope = input("Choose your operator: ")
    if choose_ope == '+':
        print(float(num1) + float(num2))
    elif choose_ope == '-':
        print(float(num1) - float(num2))
    elif choose_ope == '*':
        print(float(num1) * float(num2))
    elif choose_ope == '/':
        print(float(num1) / float(num2))

   go_again = input("Do you want to go again ? : Y/N\n")
   if go_again == 'Y':
       print("while loop will run again")
   else:
       print("program will exit")
