"""The previous script becomes very boring for the user as he has to keep on typing just numbers and of wants to interact using
simple english language he is unable to do so. Also the program terminates after one execution and if the user wants to keep on
performing operations it becomes difficult.
I have tried making a more simple and interactive calculator which allows the user to input any statement for performing the tasks. """
