In python. Please add this to the calculator and provide screenshot of the output with examples for M P and Rn. Users now should be able to use the = operator or enter to do calculations.

Program should be able to handle incorrect inputs (like other characters or symbols). If a user enters incorrect input, the program resumes from the last correct input. No exceptions should occur.

Users should be able to use the M character to save the last input or result. Users can save as many numbers as they want. Users can list the saved numbers by using the P character. User can retrieve and continue with any number they want from the list by using Rn where n is any number from the list larger than 0 (e.g. R1 will retrieve the first save element, R2 second, ) Entering invalid number should print: Result does not exist at location. List exists as long as the program runs. Everytime program is restarted the list is empty. Store list in memory.

Please provide screenshot of the output with examples. For example 10 + 20 = 30 and then when user press M it saves the result or when you press P it lists the saved numbers or Rn to retrieve R1 will retrieve the first save element R2 second...
