Python Server
The server-side is a machine on which all the operations are executed as requested by the client-side, we will perform addition, subtraction, multiplication, and division operation on the server. To do so the server received input from a client and performs the basic operation by itself. when the result is ready Python server then sends the output to the client machine.

Simple Calculator in Python Socket Programming
In this article, we are going to know how to make a simple calculator in Python socket programming.
Prerequisite: Socket Programming in Python.
First, we will understand the basics of Python socket programming. Socket programming is used to set up a communication channel between two nodes on a network. It provides Inter connected communication (IPC). The network can be a logical, local network and physical network to connect external network. In this example, we will write local socket programming code in Python.
