Using Python write a script to work like a calculator.

Using Python write a script to work like a calculator. As an example check the UNIX basic calculator “bc” or the Windows calculator “calc”. The interface should be as simple as taking the user input and some validation on the input to receive only numbers (int() data type and float() ) data type and if the user inputs a str() data type it should be converted to either int() or float() for support for both data calculations. 

Please write at least the following functions to accept as many inputs are the user enters in the command line and perform the following calculations: While the number of arguments could be different on each run, please use the proper data structure and looping through the list and perform the appropriate calculations such as (Addition, Subtraction, Multiplication, Division, Module, or remainder, Power of function ( x to the power of y withx and y could be any values) square root of a given number.
