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 some site but everything was way too complex for me to understand.

```
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':
    //i want the program to rerun itself here
else:
    print("OK!!")

```

If the user inputs Y i want the calculator to start again.
Detailed answers would be appreciated. Thank You
