Write a python implementation of a single threaded calculator server that understands a very simple request as a single string in the form of: operator first value second_value. Where operator can be (4-1-1*,or I) (for example when the server receives: - 5 3 it should calculate 5-3 and return 2). It is the calculator server's responsibility to understand request, perform the proper mathematical operation and send the result to the requester For your server program, use Port 5050 on local host (IP 127.0.0.1)
